I hope the following is not correct info regarding the CZ 75 Kadet II Conversion kits. Are there any issues with "peening" when using these units? I'd love to have one, but after reading that, I'm a little hesitant. I've never heard this before. It seems that another batch of the Kadet II Conversion kits must have been imported recently based on the number showing up for sale on GB.

What peening are you talking about?? Links to any articles or threads? I know you can get barrel peening with the SIG P226/P229/P220 conversion kits if you don't use a snap cap when dry firing or using a magazine configured to hold the slide open after last round has been fired.

Grumpy1: I own 2 of the Sig units. How do you get slide peening by using the hold open mags??

I just read the same information re: peening and the CZ Kadet. (We must have read the same source.) After an exhaustive google session, I'm convinced the peening only occurs if the operator repeatedly dry fires the pistol. All other reviews of the Kadet are glowing. I own a dedicated CZ 75 Kadet and I absolutely love it - more so than my beloved Ruger MK II and my Colt Woodsman.

When shooting any rim fire semi-auto handgun that has a hammer, I always place a soft foam ear plug between the hammer and slide and snap away. The foam plug absorbs all the energy, and won't even dent a plastic snap cap. I do this with my Kadet kit ( on my CZ 75BD ) and my Sig P226/22 and P229/22 pistols.

You can get barrel peening if the slide does not stay open after the last round is fired and you drop the hammer on an empty chamber. Now on occasion this will not be a problem but still IMO not a great idea to do a lot of dry firing. You can see it starting in the picture below of the barrel of my P226 conversion kit that I bet has had less than 30 dry fires before I switched to a magazine that keeps the slide open after last round fired.

As far as I know, cz kadet is safe to dry fire. Ymmv.



My lc9-22 it likes the hot ammo, what can I say

Yep, I'm pretty much in agreement with your posts as I too have never heard anything negative about the Kadet II Conversion units or, more specifically, about the peening until the other day. Someone had a like new one for sale online and made mention of the Kadet kit being known for peening or something along those lines. I'm not exactly sure of the wording used by that individual so I do not want to misrepresent anything. As far as I'm concerned, it's time to grab a Kadet conversion kit while they are still available!

Oh, o.k. I understand now. I thought you were saying that you get peening by USING the slide hold open mags. Sorry for the confusion and I agree with you. That is why I DO use the slide hold open mags on my P series Sig .22's.

That was me who posted those comments and its based on a friend who asked me for detailed pics and feeler gauge measurements. He was a shooter on Team Sig so I'll take him at his word he knows his way around CZ stuff as that was his sponsor before Sig.

I've never heard of it before him asking me so please don't take it as gospel...unless it really is an issue of course. I'm obsessive about not dry-firing my 22's and even bought a spare barrel on a Beretta 89GS because the previous owner was not. Its not bad but they're not making more so grabbing a spare barrel made sense.

Don't dry fire any rimfires without snap caps or other similar protection. It's a good idea to uses snap caps for ANY dry firing.

I do think that, as gun owner, we often "borrow trouble." If you get a peened rimfire mark, so what? Avoid it if possible. The original purpose of the rimfire is cheap practice. The intent of dry firing is cheaper practice. So dry fire the center fire unit with snap cap. And worry about something important, like cancer.

I've got a Kadet with 50k rounds through it. No peening. Bullseye match gun.
