CZ-75 mags!

Figured I start carrying my pre-B CZ-75 9mm for awhile. Had some brand new MecGar 16rd mags , so I loaded a few and when I went to test them , I couldn't get them in the magwell! 2 went partially in , but would not come out! WTF?

Got out the calipers.

Side to side = .800"- OK , front to back = 1.254" - OK , diagonally , uh-oh! Orig mag = 1.360" , new mags = 1.385"

Seems the bend radius in the front corners of the new mags was a bit sharper. A radius gage confirmed this and some Black marker on the front corners was rubbed right off.

Seems like a bit of whittling with a small diameter round chain saw file is in order!

From what I remember standard current production CZ75-B mags will not fit any Pre B model, and finding Pre-B mags is a bitch and costly. One mag came with my import pre-b and that's the only mag it's going to have at the time I purchased it which was about 3 years ago well used spare mags were being sold for $45.00.

The Pre-B pistols also have the mag break in them which stops the mags from always dropping free as well and that will also affect trying to seat a new 75B mag.

Just a few swipes in the front corners with a round chainsaw file is showing promise. Gotta take the mag catch out.

I got 2 mags with my pistol , 1 has the last 3 digits of the ser.no. on it.

newer cz 75 mags will not fit the Pre b models with out extensive modification to the mag well

I got lucky. The newer Mec-Gar mags I bought fit my 1991 Pre-B I bought NIB five or so years ago. Many either have to get pre-B mags or slightly modify the magwell. If you do a search for it you can come up with he instructions.

Are you putting them in the right way? The bullet should be pointing toward the front of the gun.:p

Not extensive at all. Like I said earlier , just gotta put a smaller radius in the front corners. I'm using a 3/16" dia round file. Wrapped some 220~320 grit around the file for the finishing touch. Hardest part is taking out and replacing the mag catch.
