View Full Version : CZ 75 mag interchangeability?

Do B mags fit and function in pre B's?

Generally, nope, but there are exceptions. The mag change and the firing pin safety didn't happen at the same time, so there are some very late pre-B's that take the B mags. Beyond that, pre-B magwells can be altered to take B mags fairly easily. Conversion info is pretty easy to find on the net. Haven't done it yet myself, but it looks like I'm eventually going to get to it. I 'thought' I was going to get by with MecGar 16rd mags that purportedly worked in pre-B's, but they don't work in mine. I have one working mag and ten new mags that don't fit anything, so it's probably time to correct that situation.

the flat base mecgars work in my 1984 pre-B, do not work in my 78 short rail though.

MEC-GAR flatbase work well in both my late 80's pre-B's.
Snug fit.
