Colt Z40/CZ 40B/CZ40P Magazines

Hello All, I have been looking at Colt Z40, CZ 40B and CZ 40P pistols.  I've read a lot of the threads about these pistols but still have a few questions.  1. Do they all use single stack magazines?  2. Are the magazines interchangeable?  3. Does any aftermarket company make these magazines? 4. In several of the threads it talks about using a 75B magazine (they just stick down), my 75B magazine is a double stack I don't see how it will fit, can somebody elaborate on this?  Thanks in advance!

The CZ 40 uses double stack magazines. I use standard CZ 75 .40 cal mags in mine.

eastman, Thank You for the response, I was trying to verify that.  When I contacted CZ they told me I could use the ten round (11103) $39 or the twelve round (11111) $43.

I'm still a little confused, I have been able to swap mags between my Shadow 2 and my 75B, both are 9mm, the Shadow 2 mags are dual marked .40/9mm the 75Bs are not. Do you think I will be able to use the Shadow 2 mags in the Z40?  What about the 75B mags that are not dual marked?

Again, Thank you!

The only difference between a CZ-40/Z-40 mag and the standard CZ-75B  .40 Mag is the base plate.  If you could ever find some 40B base plates you'd be home free.  The regular .40 mags work fine, but just don't look right in the grip.  (Compare the base plates and you'll see the obvious differences.)  I had one of the 40B, and it's one of the few guns I regret trading away.  (I've since gotten comfortable with .40 S&W, but wasn't back then.)

Some years back when the .40 versions of the CZ was first introduced the CZ .40 mags (I had one back then) and the CZ 9mm mags all fit in either gun properly,  but the .40 mags wouldn't HOLD/RETAIN the 9mm rounds properly -- I think the gap of the feed lips was too wide.  I don't know if that is still the case; CZ has had a lot of years with newer .40 models.

(I've had a number of .40 guns with 9mm conversion barrels, and the only problems I ever had with any of them when shooting a 9mm round in a .40 gun using a .40 magazine and a 9mm conversion barrel was with some hollow point rounds: some of them would bite into the feed ramp because the 9mm rounds (in a .40 mag) hit the feed ramp differently.  I got 9mm mags for those guns.)

Walt, thanks for the information and insight!
