My vote would be 22/45 (MKIII). I like the aftermarket for them. The suppressors look awesome on them. The controls and grip angle mimic a 1911. You can get them with rails standard and put a red-dot on them so you don't have to concern yourself with raised sights. The only downer is getting the bushing for the magazine disconnect, stupidest thing they did, luckily it's a 5-10 dollar fix and you're off to the races.
