I got a Colt 1991A1 in the early 90s. At about 100 rounds the plunger tube came unstaked....this was my first 1911 platform and really p me off.....I thought this-"so much for Colt quality"...
That malfunction had nothing to do with how much knowledge anyone has about the platform.
That said, I have had some pro work done on it and have since aquired a Springfield mil-spec...still the easiest centerfire pistol to shoot well.
