As I'm sure some of you know (and for those that don't) I recently purchased this Sig 1911 Long story short: I'm looking for some reliable magazines without breaking the bank. The information I've gathered so far is almost dizzying with all sorts of opinions, truths, and BS. With this particular gun the factory mags it shipped with run great (non-marked 8 rounders, look like CMC) but when I purchased some 7 round Colt hybrid magazines it began to choke. One magazine's follower jumps the slide stop and makes the mag not drop free on top of not locking the slide back. The other will sometimes give me a failure to return to battery. It's happened once at the range and a few times when hand cycling the slide. Any suggestions or ideas?
