9mm CZ-75A and CZ-75B magazine difference

Hi,

Older round trigger guard CZ-75As will not accept the newer CZ-75B magazines. If you need to buy older magazine from CZ-USA, order Part #1114.

The former measured out to .785" compared to the latter .802" width.

Ask me how I know.

My understanding is that it is possible to slightly modify the frame of a pre-B CZ-75 to accept B magazines (which to my knowledge are the only ones being commonly sold today by CZ or Mec-gar).

For my edification, what the devil is a CZ-75A? On a CZ-75B, the "B" denotes a firing-pin block, not part of some A-B-C-D sequence. (And "D" denotes a decocker.)

Are we just referring to the original CZ-75?

Technically, there is no such thing as a CZ-75A. There is the CZ-75 (which went through many iterations and changes, with a good bit of overlap in terms of production years) and the CZ-75B, which has the firing pin block, and later variants.

Pre-B CZ-75s may have round or square trigger guards, slim or later "full" slides, variations in the slide serrations and grip designs, and varying hammer designs (spur vs ring), depending on when they were made (again, with a good bit of overlap).

Also, because the evolution was incremental, there are supposedly some later pre-B CZ-75s that apparently will accept the current CZ-75B magazines.

Round trigger guard,
No firing pin block
Can be carried in the cocked and lock mode like the 1911 (safety does not decock)
Accepts only the narrower magazine.

That's the answer I was looking for. World order is restored.

(By the way, I dunno if everyone gets the MiG-21 reference, but I've always been on it.)

Oh, that did take me a long minute to understand.

The NATO designation for the Soviet MiG 21 supersonic fighter is "Fishbed".

Local car dealer had one on display for catching the eye of the passerby, seeing as the business is named Jet Chevrolet.

Just to expand on that a little without derailing the thread, NATO designations for fighters all began with an "F" (such as Fresco, Farmer, Fishbed, Flogger, Fitter, Frogfoot, Fencer, Foxbat, Fulcrum, Flanker), while bomber designations, began with a "B" (such as Beagle, Bear, Badger, Blinder, Backfire, Blackjack).

This was a new take on the system used to label Japanese aircraft in WW2. Back then, fighters had male nicknames (such as Claude, Nate, Oscar, Zeke, Tony, Jack, Frank, George), while bombers had female nicknames (such as Val, Kate, Betty, Judy, Jill, Dinah, Nell, Emily).

I know a lotta mostly worthless stuff.

Can confirm the frame can be modified. I used to have a transitional model 85. Just invovled filing out the top of the magazine well a bit and then it worked fine.

B versions can also be carried cocked and locked unless its specifically a decocker model
