CZ52 pistil slide cracked

7's · Mar 9, 2013

Is it possible to weld this? Anyone tried or know what kind of steel it is? Any info would be greatly appreciated as I have 2 with cracked slides and the cracks are both at the ejection port to the bottom of the slide. I have not yet been able to find any slides or parts guns to be able to replace the slides.

Not uncommon. A proper repair will equal or exceed the value of the pistol. Not worth it. Hot ammo and pieces of spent brass getting jammed inside the chamber can cause it. Other times it's plain-old metal fatigue. Cut your losses by selling what parts you can.

If possible I could do the welding myself, just wondering if the metal is of a grade that takes to welding. I'd rather not just give up but I do have 2 others that are in good firing order

Problem is the risk. So far it's a cracked slide. Next time could be a kaboom with injury to you.

id just sell it for parts.

Well, I guess maybe I will strip them down for parts and sell off what I do not need then. Any ideas what would make them crack there?

All 52 failures I have seen are slides, idk why but that's the weak points.

Some surplus tok ammo I have heard is loaded hot. Not sure what surplus it was though.

The metallurgy is pretty poor on those CZs.

Used to be you could find CZ-52 parts on GB and such. Not now. :sad20:

Fact is you'd prob'ly get a lot more for the parts you have than you paid for the pistol. It may be time to let it go.

Well the good part of this is that I have 2 good shooters and 2 with the cracked slide issue and it is pretty thin where they are broke and judging by what I can see from the break it looks pretty cheap in they way of grade of the steel so I will probably strip them both for parts keeping one as my parts and sell the parts from the other on GB

I bought them both with cracked slides for next to nothing so I have no idea but have fed my other 2 everything and so far no problems, but the Tok I had was a picky eater

Slide is about $60

Look around APEX had them at $25 at one time. Hot ammo does it. Maybe not today but for sure tomorrow.

DO NOT attempt to weld it back together... Unless you have equipment to fully anneal it, data on how it should be heat treated, a heat treating oven and hardness testing equipment. I'm betting you don't. It would cost you FAR less to buy a few more of them.

I'll do some looking and see what if any I can find

I only have the welder but have a few friends that are machinests that do have all of that but its really not worth the time at this point

Um...no.

Um...yes.

The cracks are most likely due to to using very hot ammo. I cant remember what country had it, but there was one eastern block contry that produced very hot ammo for a full auto MG.

That's another internet myth. It's usually Czech ammo that's cited as being higher pressure. It is not. Accurate Arms tested a bunch, and found none to be markedly higher in pressure.
