Mag dealer at local gun show told me EAA Witness Compact mags are identical. That's a cheap alternative, if it works.
Can anyone confirm that? I'm also looking for a PCR so I can't confirm (sooo hard to locate. The local CZ-specialists are all sold out. Maybe I'll just wait til October when the new PCR ships).
I am using hi-cap EAA Witness (full-size) mags for my CZ-75B, no problems with them.
