These are Mec-Gar CZ 75B 17 round magazines. They are also compatible IN THE SAR K2P 9mm, SAR B6, SAR B6P, SAR CM9 GEN 2, Sar Mega 2000, Sarsimaz Kilinc 2000 Mega, pre 2005 Bul LTD Cheerkee, Bul Cherokee-g, Magnum Research Desert Eagle Pistol, Tristar P-120, L-120, S-120, T-120, Canik 55 L-120 and Shark-FC pistols. This magazine if for the full sized pistol. It will extend past the grip in the B6P Compact. Some customers tell me that it is a little hard to lock them into the magwell in the EAA SAR K2P 9mm and EAA B6P. If you find that is the case just give them a little tap on the base to insure they are inserted all the way. After a while they seem to become easier to lock in and they work fine. You can also remove just a little bit off the top of the magazine base plate to give a little more insertion clearance if you find insertion too difficult. That isn't normally necessary but some find it helps. The Mec-Gar CZ 75B 19 round magazines have a little more clearance between the grip and the base plate so those magazines seem to lock in easier (haven't heard of anybody having a problem with the CZ 75B 19 round magazines).
THE MAGAZINE DOESN'T FIT THE SARSILMAZ SAR 9.
The magazines aren't compatible in the CZ 75 Pre-B. They also don't work in the CZ Custom SP-01 pistols with the magwell, the magazines tube is too short.
The CZ 75 PRE-B MAGAZINES HAVE A SQUARE CUT NOTCH IN THE REAR OF THE MAGAZINE TUBE BEHIND THE FOLLOWER. THE CZ 75B MAGAZINES HAVE A MORE U SHAPED CUTOUT. CZ 75 PRE-B MAGAZINES WILL FIT AND FUNCTION FINE IN THE CZ 75B. THE CZ 75B MAGAZINES ARE A LITTLE WIDER AND WON'T FIT PROPERLY IN THE CZ 75 PRE-B. THE CZ 75B MAGAZINES ARE A LITTLE WIDER AND THEY WILL BE TOO LARGE TO INSERT INTO THE MAGAZINE WELL (TOO TIGHT OF A FIT).
