CZ 75 - Observations...

I have been wanting a CZ 75 for some time, but couldn't decide on satin stainless or polished stainless. Then, I saw a glossy blued CZ and that was it, I had to have one. So, I found a nice one and bought it.

First impression - what a beautiful gun! Gorgeous finish. Lighter than I expected. Nice balance and feels nice in my hand.

Second impression - man, this thing has a lot of parts and looks difficult to fully disassemble. Very nicely made; smooth, tight slide to frame fit.

Third impression - trigger is ok for a DA/SA - not as good as the one on my Tanfoglio Stock.

Oh, one more thing. When I took the gun apart simply to clean it and reassembled it, I thought I lost a part. It seemed to me that I remembered a cap or something covering the hammer pin hole. I spent an hour looking for this elusive part that must have fallen between the cracks on my sofa! Oh, crap, now I'm going to have to order this little thingamajig that covers that hole on the frame! So, I get online looking for the name of the thingamajig I thought I lost and after seeing another picture of a CZ75, realized that this is just how they are made. I know I'm a CZ novice, but I had never noticed this before. Just wondering if I'm the only one who thinks this hole is a little odd?
 
A helpful tool for dis-assembly and re-assembly is an exploded parts view. CZ offers these and they are available on the web.

Most likely you have a CZ75B, which is different from the CZ75.

This makes it a lot easier to do the job and know if you have missed a part or not. Good assembly practices also help.

No I don't think that hole is odd. If we're talking about the same hole. I've been seeing it for years so I think nothing of it.

Do you have a picture of the hole you're speaking of, or the name of the pin?

When I was able to find a close-up picture of the CZ 75, it became apparent to me that the "hole" is supposed to be there. It just seems like an odd way to retain a pin or keeping it from backing out. Especially since you can't remove the pin without completely stripping the rest of the frame (except trigger). I
 
The older CZs used a firing pin stop, a plate that fit in a machined slot at the rear of the slide. A hole in the middle of the firing pin stop retained the firing pin by letting only the end protrude.

The newer CZs (those with a B, which denotes firing pin BLOCK) use a firing retention roll pin through the slide at the rear. That retention roll pin rides on top of the firing pin, in an indented area. The end of the indentation keep the pin from going to far foward when it's hit by the hammer, and retain the spin within the slide when its not being slammed. You have to remove the retention roll pin to remove the firing pin. The newest models, I'm told, have a solid roll pin rather than the original roll pin, later upgraded to have doubled (one inside another) roll pins.

If you're used to seeinga firing pin stop plate, you'd be wondering where it was, and should also be wondering WHAT was holding the firing pin in the slide. (Grin.)

If you haven't done so already, check out the CZ Forum, here: http://www.czfirearms.us/index.php You'll find all sorts of help with stripping and tuning... and have also access to some REAL authorities and experts.
 
Walt, the "hole" I'm referring to is where the hammer pin retaining peg is located. Thanks for referring me to the CZ forum, that's where I figured out what this thing was called. I've just never seen any other gun use this method of retaining the hammer pin....and, why just for the hammer pin? Just a curious design feature to me that doesn't show up on some of the clones I'm familiar with. Like I said, I'm new to the CZ's. I suppose I expected it to be more like my Tanfoglio Stock 10mm, but it's not.
 
I seem to remember CZ having breakage issues with the solid (or single roll?) FP retainer pin so they switched to a double nested roll pin design. Excessive dry firing would break the solid one.

You're right, it looks like a small hole in the slide.
 
I looked at a used 75 this past weekend, matte stainless lower, wonderful blued slide.

If I hadn't just bought a p-09 two weeks ago she'd come home with me.
 
that mirrored my first impression, I was like "man, I will never take this apart". I finally got around to it about two weeks ago(followed along with a couple good yoututbe vids), easier than I thought, but still not easy. the only real pain for me was getting the trigger spring back in. I have had my lever action for over a year now, that thing I will truly NEVER take apart.
 
If you haven't already, you should visit the CZ Custom and Cajun Gun Works sites. CGW has a nice kit (Ultra-Lite S/D) that lightens up the trigger and gets you an improved firing pin and roll pin.

CZ enthusiasts are picky about nomenclature. That was almost certainly a 75B and not a 75. The "B" indicates a firing pin block mechanism, and the original CZs didn't have that feature. No 75s ( pre-75Bs) were ever made in stainless, as far as I know. (You might find something like that made by Tanfoglio, howver.)

That color and steel combination is a really unusual mix. I've never seen or heard of a stainless lower that didn't have a matching stainless upper; ditto a high-gloss blue slide that didn't have a matching frame. . Are you sure it's stainless? I wonder if it was possibly a satin nickel frame -- which is a bit more common? (I have an 85 Combat in satin nickel. It's my favorite CZ finish.) You will see some nickel frames and various types of black slides.

There are also a few silver polycoat frames floating around. That was more common in Europe, I think.

My first pistol was a Ruger MK III Target. After that any other pistol is easy to fieldstrip in comparison. My second pistol was a CZ-75B and after taking it apart the first time I thought "wow, that was easy" :D
