No disrespect intended toward the OP, but we've had a gazillion (okay, maybe only a couple hundred) threads on the topic of 1911s with barrels under four inches in length, since, oh, about the inception of this forum ...
That said, I've owned two Springfield Armory Loaded Lightweight Micro-Compacts for almost then years now. Fit and finish superb, wonderfully built and beautiful little pieces. Both are totally reliable and one is more accurate than a couple of my full-size 1911s.
Not as fun to shoot with lighter weight (165 - 185 grain) +P, must be kept clean and well-lubricated, will shoot any 230-grain JHPs (including the Golden Sabers with those long fat noses) all day long.
However -- the shorties WILL clearly display the results of limp-wristing. I suspect this is the cause of a lot of the aspersions cast toward the 3-incher's reputation for reliability.
