I just got one from Midway a couple months ago. That was pre Covid/political hysteria. Actually, what I got was a 17rd MecGar CZ75B mag with the blue follower and plastic base plate. I have the Sar K2P and I believe mags are interchangeable between the K2P and the B6P. I have the 17 and 19 Rd CZ mags for my Sar. They both function fine and lock the slide back, but the CZ mags require just a hair extra force to lock in.
