Altering the Slide Launch on a CZ-52

This standard Czech-made pistol is a favourite of many – in a unusual approach. It fires a strong submachine gun (7.62 x 25) — and brings good luck in an “ugly” approach. Like it or hate it – and many individuals adore it!

However – it has a couple of flaws. A serious shortcoming is the decoupling mechanism (brief model – do not belief your decoupling!). A second shortcoming is the weak firing pin. Lastly, a 3rd weak point is the dearth of a thumb-activated slide launch.

As soon as your slide is locked to the rear, the one technique to launch it ahead is to stretch it again once more by hand…after inserting {a magazine}. There isn’t a thumb tab to press to launch the slide like extra trendy autoload pistols.

This weak point is straightforward to repair – there are a number of aftermarket slide launch mechanisms which might be simple to put in. This is how you can do it.

Earlier than you start — take away the journal and examine the chamber once more to ensure the gun is protected. Then take away the only U-clamp that holds the handles in place.

I discover it virtually unattainable to take away the U-clamp with out scratching the wooden on the deal with. You may’t transfer the clamp by hand – it’s important to insert a screwdriver to pry it off. Each time you do that you simply lose a bit of little bit of wooden. So… do not do it too usually!

After eradicating the clamp, the handles ought to launch. You’ll have to “get them to work” by inserting a pry device (skinny screwdriver) between the deal with and the body. Do that close to the again of the deal with.

The handles might not come straight up — there’s a bit of undercut within the entrance…it’s important to carry from behind first. you need to.

Then I deleted the slide. Use the identical steps you’ll use when cleansing the gun.

As soon as you’ve got accomplished this, be aware the place of the slide launch spring; the spring ought to be on the prime of the discharge tab.

This is the difficult half – there is a single pin that holds the slide launch in place. Flip the body on its facet (slide down loosely) and use a punch to take away the pin. I needed to give mine a couple of arduous whacks to get it going. Upon getting pushed the pin throughout, LEAVE THE PIN PUNCH IN PLACE!!!! That is necessary as a result of the take-down launch is held in place with the identical pin. Because the punch is now holding the discharge in place, the discharge of your launch might come out of the body should you take away the punch!

Take away the slide launch. Pull it off the punch and angle it out of the body.

If in case you have a substitute prolonged slide launch, examine it to your previous slide launch – be aware the prolonged thumb tab. This prolonged tab makes it simple to manually launch the locked rear slide.

Twist the brand new slide launch into place and place the outlet over the punch. Actually, mine felt actually gritty after doing this. I took it off and cleaned the body and again of the discharge. I lubricated and changed each elements. It labored significantly better, however nonetheless felt a bit grainy. I believe I might have polished the again of the brand new slide launch to make it smoother.

Make sure to place the slide launch spring in order that it’s on prime of the slide launch finish!

Put the pin again in — ensure you let it slowly exchange the punch pin in order that the removing launch stays in place. After manually pushing the pin about midway, the punch pin fell out and I hit the slide launch pin again into place.
Exchange pin. Word the big thumb lock on the brand new slide launch!

Time to place issues again collectively. We’ll begin with the handles.

Word that there’s a small angle minimize out on the entrance of the deal with. This prevents you from urgent the handles straight down into place. You have to first slide them ahead after which press the again of the deal with.

As soon as your grips are snapped in place, slide the U-clamp again into its notch. Word that the U-Clamp can go the “proper” or the “incorrect” path. Word the angle on the clamp to pick out the “appropriate approach”.

As soon as the handles are again on, exchange the carriage – and also you’re accomplished!

Although you now have a thumb tab on the slide launch, needless to say you might have to press it actually arduous to get it to work.
