Any alloy 1911 I have is always used with the classic Wilson Combat 47 magazine. The polymer follower won't peck away at the feed ramp like a metal follower can. And they are legendary for their reliability. I prefer the 7 round version. They seat more uniformly than the eight rounder and the stronger spring ups the reliability. The loss of one round? Everyone is so capacity oriented these days. One generally runs out of time before ammo. If the problem is not solved within the time span of the first 2-3 shots, more bullets typically don't save the day. I know, I know, never enough ammo for a gunfight. I get it. But a realistic evaluation of my low risk lifestyle means eight rounds total of .45 is probably enough, with another mag for a reload, and more importantly I am personally VERY confident in this platform and my proficiency/comfort with it. And confidence can't be over rated.
