CZ 27 AND CZ 24 MFG DATES? CAN ANYONE HELP

[mbliss57]

I bought what I believe is an early CZ 27, although it is not marked CZ27. I have an FNH factory CZ27 and it looks just like it except for the grips and markings.  It has a 4 digit serial number in 6652.
 The factory markings on top of the slide are correct as is the proof stamp on left side of frame.  Year of Mfg is 1930 if the marking next the the CZ with a V on top in a circle.. rollmark on the left slide toward rear. Serrations in slide are not vertical like my other CZ27 though. The slant toward muzzle at the top.  I can send pics if anyone interested. It appears to be a fairly early CZ27. I would like input/verification if possible. The gun was not very expensive so I am not concerned about value..I bought it because I liked it. It adds to my 2 other CZ .32ACPs and 9mm.

It sounds like you have a CZ 24. Externally, they look very similar to the CZ 27 but the slide serrations are slanted. The internals are different as well.
Also, the year stamp is a Czech Army acceptance stamp, not necessarily the year it was made.

Nice post GWVT. Learn something everyday.

Don't we all, brother!

Thanks for the info.. I thought it was a CZ 24 after I studied it/pics  a bit. But I tried to chamber a .380 ACP round  and it didn't fit. The barrel is chambered in .32 cal. That's why I thought it must be a very early CZ27.  The mag for the CZ 27 and 24 are identical. I will tear it all down and take pics.

I have a CZ 24 that came with two CZ 27 magazines (marked P. MOD. 27) that work fine for it. I've read that that's not uncommon. I'm not aware of any CZ 24 being chambered in .32. Photos would help.

[mbliss57]

I broke down the pistol. It is a .32ACP. Both barrels interchange with the other CZ27 I have. I have pics on photobucket.
Here is link.
password is cz2427

I didn't see where to enter a password but if the barrels are interchangeable it must be a CZ27. The CZ 24's barrel is completely different as shown in the photo.

[mbliss57]

I will make it public  for a few days until I have time to post them inside the thread..  That password thing is iffy.
 Or were you able to see pics?

And.. after I got both guns out and watched a CZ 24 and CZ 27 disassembly video I was convinced it was indeed an early
CZ 27.  I have both .32 and 380 ACP ammo. The .380 will not fit into the chambers.





 







Generations of .765mm CZs



There are subtle differences in the barrel thicknesses and the takedown lever widths. The barrels do interchange.
The newer CZ 27  take down lever will fit into the older but not the other way around. Machining/tolerance differences I assume.
Now that we have established it is in fact an early CZ27...With that S/N does anyone have an approximate date of manufacture? plus or minus a year maybe?  6652.

Thanks for the help.   BTW I am a regular on the S&W Forum. Same user name. If you have any questions concerning them I may be able to help.

Interesting. It seems like more research into the early CZ 27 is in order. Clearly all the parts match. I know with CZ 24 that the older ones had wood grips while the later ones had Bakelite grips.
After a quick search, apparently there were CZ 27s made with angled serrations - it sounds like you have a relatively rare pistol.

As for the date - that is probably a factory date stamp. I don't see the military acceptance stamp that would precede it. I know about the CZ24 somewhat - I don't know much about the 27 and it looks like they did stamp the year on these at the factory.
You could start here for s/n info:

I guess I'll need to change my rule-of-thumb for telling the difference between CZ 27 and CZ 24. The CZ 24 has five slanted serrations. The CZ 27 has four serrations, which are usually vertical but may rarely be slanted.

I have a very early CZ 27 s/n 6652  and I just bought a CZ 24 on Gun Broker  s/N 127146. Can someone help identify the years of manufacture?

The CZ 27 is posted in another thread..

Any help would be appreciated.  Also any help finding where I can find them myself would be more appreciated so I don't have to ask !!

The 'CSP' marking indicates use by Czechoslovak gov't Postal System.

[mbliss57]

The Postal Service... That would explain it's very good condition.
Here are the CZ 24 and CZ 27 side by side. It's very hard to tell the difference except for the # of slide serrations when looking at them externally. Internally the 9mm short with the barrel twist makes them very different.
I am still looking for any help with dating these... And thank you all for your help.  Also I could use help locating a correct grip screw for the CZ24.

My understanding is that the "J 'lion'  37" on the 24 is the acceptance mark from the Czech army and the '37 indicates the year accepted.
I have one with the same stamp but s/n starting with 177 with Bakelite grips and I am guessing it was made in '36 or '37 since they were really cranking them out around then and were unlikely to have sat around for long but I may be wrong. The s/n's went up to the high 190's afaik.

Your earlier s/n and the wood grips would indicate that it was made somewhat earlier than when it was stamped accepted but I don't know if there is a reference for the years to s/n. There may be info as to when they switched to Bakelite grips but I don't have that at hand.

I don't know about the screw but you can check numrich and buymilsurp. I know I got springs for the 24 from the latter
