LW, it wasn't my decision, but of the Dept of the Army, when they went from the 1911 to the 1911A1. The Ordnance Section found it worked better with the AMSH for MOST soldiers. The short trigger allowed for better combat shooting by placing the first joint not the finger tip on the trigger.
Granted all of the short triggers, FMSHs, etc are now made for personal choice. The Military made the decisions it did based on the masses, not the individual.
Speaking as someone who has shot 1911s from 1913 dated models to the highest tech wizbangs, with AMSH, FMSH, short/medium/long triggers, 1.5lb trigger to Colts wonderful 8+ trigger pull; I can state one thing if you put the front sight on target bullet hits there. As for all the other crap shooters hang on 1911 style pistols, for the most part it is and turns a weapon into a toy.
A good 1911 needs good fixed sights-adjustables tend to break at the worst time, decent trigger-anything around 5lbs will yield comabt accuracy, no sharp edges, a tactical style thuimb safety-ambi if you are a lefty, and for better recoil management/help stop hammer bite a beavertail. Most barrels shoot better than the average shooter so the factory barrel is generally good enough; save the money practice more. All of those extended slide stop levers, mag wells, extended mag releases, carry comped OMs and Commanders, tungsten guide rods, FLGRs do nothing to improve the function of the 1911.
Must be that damn government training, and having studied under Chuck Taylor and at Gunsite. KISS and it works better. I have lived on the edge and personal 1911 has an AMSH S&A magwell; not for my blinding reloads or even to assist them---they just look good, besides most magazines have a pad on them these days.
