I have a couple 8 round mags for my colt commander. and Im not talking about the ones that stick out the bottom. im talking flush bottom, 8 round mags. I only carry 7 +1 so that I can unchamber and pop that +1 in the mag if I ever wanted to, like when I get home and dont want a locked and loaded 1911 on my hip while Im around my 3 sons. I have never had an issue with it at the range even with 8 +1 in it. Im sure if I left it in my car for a year or two with 8 rounds in it the spring would compress and I would have a problem. I know Colt made the mag 7 rounds and left that space at the bottom for a reason, so the spring would last. has anyone had any issues with 8 round mags fully loaded.
