My opinion only for me. Might not suit you or anyone else. I have a long familiarity with 1911 pistols, from years of Bullseye competition, more years of banging away at club events and just plain fun banging away at innocent steel and paper targets. Arthritis in my hands makes the .45acp difficult and painful, so the 9mm it is. For every day carry, an aluminum compact frame and 4" barrel fits my needs. Springfield Armory offers their 1911 Compact that fills the bill. Fitted with Tritium night sights and a Crimson Trace grip laser, day or night, indoors or out aiming is well taken care of. Originally, the pistol came with ambidextrous safety which was replaced with a left side only. This so that the right sided safety cannot be wiped or brushed off while holstered. Slightly extended slide release fitted to allow easy thumb release. (small hands) Magazines for carry are Wilson Combat 8 rd flush base and two 9 rd as back up. So I wind up with a fairly light accurate pistol with a clean crisp 4 lb trigger (untouched from factory) easily concealed and reliable. Suits me just fine.
