No. They don't accept S&W mags.
They will take the new 17-19 round (9mm) mags you can get from the CZ Custom shop, and nearly any "clone" mag made for a small frame -- from Tanfoglio, Witness, David, IMI, Magnum Research, etc. In a few cases, the "clone" mags may not lock back the slide, but that's rare.
CZs come in two basic design sizes: 1) the standard CZ (for the 75B, the 40B, SP-01, and the compacts: P-01, PCR, etc.) and 2) the larger 97B and 75 Tactical Sport frames, which use much larger mags.
Tanfoglio/Witnesses originally came in the same small frame, and Tanfoglio expanded to build a larger frame version for .45s and 10mm. Now the Witnesses are available new only in the larger frame.
Mags for the larger frame guns won't work in the smaller-framed guns, like the standard CZs, and vice versa. Mags for the CZ 75 Tactical Sport won't work in the standard CZ, so be careful when shopping on line.
Be careful if ordering a stainless CZ, too, as there has been three types of stainless available: matte (my favorite), medium gloss, and high gloss. The high gloss models are very, very shiney.
