Gun ČZ vz. 50/70 caliber 7.65 mm Br.

Applicants for a gun license with her to meet and probably for some time will meet the test of practical shooting, and principles of treatment arms. It's about a gun, which is often enough on the shelves to purchase at a very affordable price, giving rise to the suspicion, if at all about the gun. In short: the arms market is "low-end", often posmívaný and certainly unappreciated. I'll try to give you my experience from many years of using this pistol.

It's simple, quick, reliable and accurate gun with a dynamic conclusion, on which they are placed open sights - neregulovatelná fly, gazing laterally adjustable displacement in the dovetail groove. The gun is nastřelena so that at a distance of 50 m the impact of the missiles has agreed to deliberate the point, at a distance of 25 m is the impact site of the projectile 10-12 cm above it.

Reliability is determined by simplicity (gun disassembled for cleaning consists of 4 parts including the tray), the accuracy again by going on a gun with a fixed principal, the missile alert system of the trigger DA, which allows you to carry the gun locked with a live round in the chamber and running the drum a tap. Even though it is a gun safe, since the initiation of rounds the firing pin (e.g. the fall of the weapons) prevents úderníková fuse. The blocking its movement, until it is triggered by released. The first shot is meant to detonate by simply chamber the shutter button, with, however, is its resistance significantly higher (around 5 kN) and running longer. More shots are fired in the stretched cock, a very short amount of running of the shutter button when resistance min. 2 of the cn. Single-row magazine holds 8 rounds of ammunition.

Even if it is a pistol designed for the hub, which is currently considered for personal defense for a little powerful, nothing prevents its use for this purpose. Long decades were the guns of this caliber used by the police to this and other states as a business. This "fifty" and its successor "they've done" reliably serve the members of the SNB and later the Police of the CZECH republic since the beginning of the 50. years up to 90. years of the last century. Replaced in the service of the gun ČZ vz. 27 of the same caliber, used from the first republic. This very successful weapon was considerably more complex, had a fixed barrel and because the used system of DA, was her missile alert lower.

How to choose

The original design of the "fifties" he was after twenty years of "improved" and so was born "they've done". Most recognizable difference from the original "fifty" is a more angular plastic handle, wing manual fuse was shortened, was changed the bolt forming the axis of the striking hammer, and in some specimens also the shape of the tap. But it should be said that this "improvement" wasn't the gun, to the benefit of, on the contrary.

If I can recommend, in the event the purchase prefer the original (rounded) pattern 50 and of these pistols then those that are brynýrovány rather hnědočerveně. The guns that were originally in the arsenal of the SNB, but they were prior to the sale of remanufactured, with new nabrynýrovány, so this "telltale sign" it is often not possible to enjoy. In this case, select a gun class 50 - 52, if available. Wear not need to to worry because despite his “age“ do they have guns from the time of their service odstříleno a minimum.

In most cases today they buy these guns just "střílené", which would, however, candidates need not matter. Their durability is unexpectedly high - certainly higher than they would have according to their prices had expected. Oddly enough the highest durability showing mainly - 20.000 shots at them basically no effect. Worse is it with the rest of the.

What to watch out for when choosing a gun ČZ vz. 50/70

External appearance: we check the traces of wear e.g. wiped brynýr - especially at the edges, sights, etc., any traces of craters on my sights and other unwanted signs of excessive wear.

Remove the tray and insert one bullet. Entries must charge to stick at the same angle, what they have themselves, the charge must not be "stiff" shot up. In the opposite case are the entries spread out and stack refuse, he would be the cause of defects - jam-administered rounds of ammunition. Try to (stick, pencil, or similar tool) whether the feeder tray moves freely and whether the spring of the feeder has the necessary strength.

Try zaklektáním with the conclusion to the party, what is the clearance in the grooves - moderate, but not excessive. Several times, draw the conclusion, whether it goes smoothly. Draw the drums tap and the gentle slow pressure to try running the trigger - length, resistance and whether nezadrhuje - no jumps, stairs, and whether it has a slump after "the shot". Avoid while the impact of the hammer on the firing pin - thumb it last! Repeat the test several times.

Remove the conclusion. The barrel should not have traces of corrosion and at the edges of fields should not be remnants of the carboniferous. The gun should be clean - even in different hard-to-reach places such as the edge of the cartridge chamber can be checked with a toothpick. Check for wear grooves on the conclusion and on the body of the gun - this is however not a very informative finding.

Most evident wear is the conclusion at a point just behind the opening for the fuse firing pin where it hits the top edge of the striking tap after it is in reverse motion conclusion after the shot finally, the cock stretched to the limit and its own dynamics is then returned back. On the ledges, milled to a conclusion arises roztlučené place, which may interfere with and after a time also interferes with the hole for the pin the firing pin and to limit its momentum. This is a substantial defect, because on the smooth mobility of this insurance depends not only the smooth progress of the execution and thus also the accuracy of shooting, but also the drop safety of the pistol.
Conclusion hold the muzzle down and rod, pencil, pen, or other suitable object push down the pin the firing pin in. The firing pin, yet hidden in the bed for the bottom of the casing shall own weight come out. Its tip must be solid and round. After the release of the fuse must be the firing pin again to hide. The spring of the fuse must be sufficiently strong (the force required to compress the fuse box a big). The fuse must move freely, without binding. Push the back part of the extractors in the breech. Is kyvně seated on the pin, on the left hand side must be the conclusion of the eject warning cross, the front has to lean out nail extractors.

Try the side clearance of the striking hammer, and both a stretched and running. May be only slight, especially important is the will to pressure from the left. Its existence could indicate neopravitelnou failure and thus destroyed the gun - t. zv. a "cracked eye". Failure is detectable until complete rozborkou pistol, to which it is entitled to a gunsmith. When you use will cause this fault at the earliest occasional selhače soon, very soon but the gun stops shooting completely. It is so about everything, what you in the shop they tested.

Other acts are already rather for "advanced", but not a lot of them: unscrew the connecting screw pažbiček and remove it. Check the visual condition and the tightening of the nut axis of the striking hammer on the right side - just vision. Attracted to the body of the gun cover plate of the mechanism, there shouldn't even be a minimum gap. The nuts must be in a position in which it is secured by a hex recess in the right pažbičce. Do not tighten it more, it could cause deflection of the right cover plate of the mechanism and the deficiencies of weapons..

Gun ČZ vz. 50/70 - part II. - defects and their removal

The most common cause of defects during the shooting is jammed - nepodaný charge. The defect is clearly caused by excessively gaped inlets of the tray. This is a result of long-term wearing of the full number of rounds in the trays. Unfortunately this is tainted by the majority of the trays that are on the market. It is well identifiable "willingness" of the top of the hub is "stiff" - described in part I.
Removal (if not maybe a replacement tray for flawless) lies in prevention - i.e. in that it does not use its full capacity. I loaded 6 rounds in the magazine and one in the chamber provides sufficient firepower capacity.

Before each loading tray to the arms need a bushing of a charged stack push on a solid object to each other so that the top charge was with edges cable glands parallel.

With the by the hub is closely related nedovření conclusion - the jam hub was not so strong to completely avoid the charge, yet sufficient, to energy returning conclusion wasn't enough to perfect the charge. Lever cut-off lever remains compressed and the shot is not possible. Usually it is sufficient to finish off the conclusion to the correct position of the stroke of the palm - crude force.

The failure of the hub can occur through the fault of the guns when it was illegally interfered with the weapons. Trying to "lighten the trigger" through the intervention of the trigger barbs - but otherwise - it comes down to mainly the slow and "sensitive" starting is a drum tap is released and hits the firing pin before it is his insurance arm of the sear sufficiently compressed and the hammer released. Then, if at all, is a matchstick "klepnuta" - is the energy of the firing pin is too small and is not sufficient to initiate ignition of the primer mixture. In a self-defense situation it is sufficient to use the DA "denting" the trigger. In that case, it is always released fuse firing pin and to the initiation of the hub will occur. Also when manually stretching and re-pressing the shutter button, most often the shot will occur.
The occurrence of this defect should always lead to a visit to the armorer and replacement of modified parts - the sear and the hammer.
The manufacturer guarantees the faultless function of the weapon, is maintained the resistance of the shutter in the mode of SA in the amount of 2 kN and greater. Generally many years of experience with terčovou the shooting of this weapon leads me to the claim that the reduction in the resistance of the trigger under the 1.7 kN may be the cause of defects during the shooting, taking the shooting accuracy has an effect negligible.

Often enough it happened that the first blow to the items "went up." When an automatic charge at the other shots to avoid. The difference was normally about 12-15 cm (on the target instead of "10" was a "6" on top). To eliminate this phenomenon enough to transfer the target point when the first shot of this distance below, but mainly worked to lubricate the bullets oválením after oily cloth or foam - commonly used in pistols Margolin 0,22 LR to ensure the automatic function of the weapon. The explanation of this phenomenon has never been paid attention to. I believe that there is accumulation of carbon on the front edge of the cartridge chamber and thus at a much slower return conclusion when manual stretching is not charge fully finished off in the chamber. When the shot then the shot is not immediately vtlačována in the bore, but a few hundredths of a millimeter flies freely and only then crash into the transition cone of the barrel. These nanosecond of freedom of movement of the projectile will be reflected increasing the angle of the stroke and thus the intervention on the target about the knowledge of the above.

Unauthorised modifications and interventions in the mechanism of the gun

However "poke in the gun" has always been prohibited, the high resistance of the trigger always seducing to attempt its reduction. It is true that with a new series of weapons, which has “nearly four pounds on the trigger“ is accurate shooting difficult available for sale. Weaken the drums a boost tap is a ridiculous idea, on the resistance of the shutter button has no effect. The most important component of the resistance of the shutter forms a spring force striker fuses. Push the fuse into the lower position (remember, how there has been inserted!), towards the rear vyklepněte the firing pin, then pull the fuse, in which is inserted a spring. Can tolerate shortened by 1.5, a maximum of 2 threads. I do not recommend replacing it weaker, might not reliably cover the firing pin. After deposing check the functionality of the fuse in a manner described in the previous section.
While you well inspect the degree of breaking-up of bars skirting - described in the I. part. If because it won't fuse to pull, carefully remove burrs extending into the fuse block "shaft" so that, in her fuse was running while tightly, but smoothly. It also in most cases remove the "scrubbing" of the trigger.

The emergence of the next wear and tear can reduce mild opilováním the upper part of the striking hammer so as to substantially swelled area, which devastates the machined rails in the end. Degree of pollen you find when you removed the conclusion and stretched tap: the resulting surface should be parallel with the path of the conclusion, and should extend slightly beyond.

In no case do not interfere with each other into the interlocking barbs of the sear and the striking hammer and it did not attempt to Polish, even sebejemnější. The surface hardened layer is extremely weak and, moreover, these cogs fit together in exactly the specified angle, which you certainly have not done that.

Also do not interfere with the spring of the sear, though it is sometimes tempting, because it is well accessible and its weakening actually reduce the trigger pull quite profusely. However, the risk that the gun stops shooting, it is just as hearty.

To further adjust the already is entitled to really a gunsmith (try checking). The only spring left and that will help in reducing the resistance of the trigger is a hairpin, which one end rises into the shot, trigger pulled with a breaker and the second returns the trigger forward. To get to her but can only gunsmith - the result is a pistol, the stripped down "to the ground" - only to dismantle the ejector, extractor and press the barrel.

The spring can be "inside the eye" slightly and evenly throughout the circuit to "draw" a round needle file in it - so about a tenth, but all three threads. Before restarting assembling can be polishing all the parts that are consecutive shifted, touching and below. The resulting effect is startling, the trigger pull is reduced from the original more than 3 kN on a pleasant, less than 2 kN. Reflections on when viewed from the side of the semicircular bead can be in certain lighting conditions uncomfortable. The rear portion of the fly is meant here of filing off, however, this adjustment will help indeed to those who, without her normally shoots on average min. the nines.

I wish you much success - still the black and into the same hole!.

On the very first photo they are storage reservoirs for vz.70, by comparing the shoes (shoe), it is seen that they are significantly more angular than in the picture my pistol. In addition, they have one more inspection hole in addition - I was with only one bullet?

By the way, those holes were, of course, in the bins for both weapons, but for the "50" are in a row below the other, for "70" is the lowest of the low outside line. The one for vz. 70 has the boot of a square, for 50 was rounded.

Existed as a full foot or without shoes - by the way the pressure of the little finger on the boot will cause interference down/up, so for accurate shooting it is not so good.

Boot not storage reservoirs for vz.27, and vz.52 (there is even using a stack rozebíralo)..

Compared zásovníků:

Into the stack for vz. 70 can load nine rounds, but the tray then it is not inserted into the weapon, i.e. if there is no conclusion in the rear position. Therefore, probably not the last hole identical to the other..

Personally, this gun also known with "the boot" and when I saw the tray without it I thought it was an "accident" when it was plastic just offended. even in the book (MS small arms and machine guns) from the year 1971 is the gun taken with this tray (vz. 70 is not even mentioned) because of that issue it took some time (at least a year) hardly was a tray from 70ky. Another thing that for the presence of shoes indicates is a "strong inspiration" model of the Walther PP and the same "boot" is used, too.
The requirement that the weapon was "most similar to the PP" was even in 1948 in the award. And when it comes to the design of the fifties I think that they are signed by Jan and Jaroslav Kratochvílovi no p. Mouse (this at the same time he worked on ČZ448)
By the way, i mentioned the publication of this mentions(even much stronger than me) and I quote "the Design of the gun just followed up on known and proven German pistol Walther PP and was later put into production and into service with the designation vz.50. The requirement originated in the consequences of the problems with the gun vz. 38 and complex development of the vz. 52, MNO (which was the original by the client even if the payer was MV) just needed to resolve quickly and reliably the gun, later fifties introduced basically only in the police force (in the army it was just low).

Your contribution of 14.6.2005 "magazine for the CZ 50 has a smooth bottom of the stack and the body is provided with inspection openings in the tray for CZ 70 is the bottom of the plastic and serves as a rest for the little finger" he gave Karaco rise to discussion, which involved Drinking, Fantan, Tango and Bitaxe.
Using personal memories (Fantan) and professional literature (Bitaxe) we can come to agreement in the fact that the gun ČZ vz. 50 also had the bottom of the tray provided with a plastic rest for the little finger - as well as the ČZ vz.70, these restraints are varied in shape, for vz.70 was a square (on the very first fotu from Cichyho), for vz.50 were zaoblenějšího shape (on fotu from Fantana). There were also trays without the restraints of the little finger (see photo Piti), but they weren't too usual, and also in the book (MS small arms and machine guns) from the year 1971 is the gun taken with this tank..

Gentlemen, I'm confused. Which is the correct value of resistance of the trigger of the gun vz. 50? Min. 2 cn or "four pounds on the trigger"? If the first, where is the tensioner that pulls the two tons? How it is constructed, because it must be a fantastic faster achievement! Or in zbrojařině does not refer to the abbreviation kN kilonewton? So what?.

Of course this is a mistake, the resistance is in DA boot 50N in the SA startup 20N..

#OBI-VAN GOBI: I'm not sure if You will be able to someone answer Your question. Most of the debaters above here already goes (the author of the article has left us, unfortunately, forever), I would recommend to contact directly to the sites of gun owners as arms.kvalitne (50/70) or marksmanship (50/70), or try to ask around at the gunsmiths ....

answer maybe you will find something above (How to choose and What to watch out for when choosing a gun ČZ vz. 50/70), as he wrote a colleague Fantan 13 years ago.
