Also wanted to add more opinions based on what experience I do have, which I'm not claiming is extensive. You already said DA/SA isn't a concern, and I wanted to talk to that specifically.
I shoot IDPA & IPSC matches and run the Sig P220 which, in spite of my time with the trigger, still probably has upward of 8 lbs, maybe even still 10, on the DA. Never notice it in the least little bit, and that's just under the life-or-death situation of an IDPA or IPSC match.
So, I've been struggling and researching and renting and shooting for about 3 months now, looking for a CCW gun. Being a P220 owner and a 1911 owner, I'd already decided on .45 ACP. I don't care about any arguments over stopping power and knockdown this or muzzle energy that or whatever...don't care. I like the cartridge, it's MY cartridge, and I got that choice out of the way right up front.
Struggled with a CCO format 1911 in steel...wanted the weight but didn't want to spend a ridiculous amount of money for a finely tuned 1911 (which to me, is inherently a dumb idea for CCW). The Sig 1911 Compact (all stainless) would be my choice--my opinion is that is the upper limit of what you should pay for a 1911 for 'combat'. I've had a GI 1911 that rattles and creaks for over 40 years, and in 40 years it has NEVER malf'd in any way with any ammo it's seen. Don't need no fancy shirts, I just need the ones thats clean.
I found an M&P .45 Compact and shot it. Bought it the next day. Eight big rounds of the 45 comin' at 'cha and in a small, controllable lightweight package. So far (300 rounds only, understand) I think it's going to be a great carry. Try one. You're hearing this from a guy who had a major issue with plastic frame and no hammer, and a MAJOR beef with 'lightweight' anything--would NEVER have considered buying a polymer handheld device. I shoot tighters groups with it than I do with my P220 Elite Stainless (at 10 yards, mind you), I'm embarassed to say. That's just the facts.
Yes, it has a Fisher-Price feel and a trigger that must be made by the same folks that make the ones for Nerf, but again, I firmly believe that after a few more hours with it, I won't be hesitating on those controlled doubles. For me, I believe it's the perfect carry. It's impressed the hell out of me and I had no problem buying a P220 Carry Elite Stainless and cutting it up to make it into a stainless P220 Compact. Glad I didn't.
I know you didn't ask for another option, but hey you got one anyway! As always, try before you buy.
