PCR slide curved area
« on: October 27, 2021, 06:19:25 PM »
I had my PCR and P01 apart the other day. Why does the PCR slide have the piece of metal that's curled-up (or down when assembled) right in front of the Firing Pin Block Plunger? At first I thought it was a defect but after looking at Sootch's PCR video, his had the same thing. What is that for and why doesn't the P-01 have it? Thx.

Well it's obviously machined in not actually curled so there's that. While I think the slides are interchangeable between the two models they do have some differences such as the rear sight and the loaded chamber indicator on the PCR. The frame assembly on both guns should be the same with the real difference being the rail on the P-01 so who knows.
Maybe send a pic of both slides to CZ-USA and see if they have a reason for the difference.

OK so to add to this I do not have a way to post pics but I looked at My 2009 made PCR and it has a curved section machined into the slide just as yours does while My 2-2021 made PCR's do not and are machined straight. The earlier gun also has a different style firing pin block plunger than the new guns. What this tells me is there are just some rolling changes/revisions in the design. The frames and internals therein appear the same and the slides interchange and function just fine between the old and new guns as well. As to why they did it that would still be a question for CZ themselves but it appears to me they cheapened the firing pin block plunger design which as with all things starts with the bean counters.

OK. Thanks. Just wondering. I knew it was intentionally machined that way after I saw pics of other PCRs but at first, I did press down on it to see if it was solid or not. :D The next time I have them both field stripped, I'll look at the firing pin block plunger. 

Probably has nothing to do with the Loaded Chamber Indicator being your 2021 PCRs are machined flat in that area. I wonder if that has anything to do with the fact that I can't remove the slide (PCR or P01 -can't remember) when the hammer is fully cocked. Thx

EDIT.. The P-01 slide will not remove if hammer is cocked. So maybe that has nothing to do with it either.

I only mention the lci and the rear sight since that's the only 2 things different between the slides on the PCR/P-01. I just looked over a P-01 in the case at the local lgs/range and from the underside there's no visible difference in that it's machined the same as my new PCR's being machined the same. I'd just be curious to know when this change was implemented.
What's the difference in age in your PCR vs the P-01?

2016 PCR
2020 P01

I got them exactly 4 years apart on Halloween... not planned that way.. Strange  :)

Well that narrows it down to a design revision in that time period. Interesting.
