Yes, but high-quality, aftermarket mags should work fine. Chip McCormick, Wilson, ACT, Novak, etc. should work with any 1911. If they don't, the issue is probably the gun. I had a problem with the slide catch on my last commander. I swapped it out for a checkered one by Wilson and, though I couldn't see any difference at all between the two, the Wilson one really fixed it. FWIW, I had a good 10k rounds through my older SIG P220 before I had a problem and then learned they recommend the springs be changed out every 3k rounds. I used the old recoil spring to reinforce a collapsed vacuum line in the varioram of my 993. Worked like a charm too.
