I have one of these with a slim grip set-up. You could throw an arched housing in there and bang away.

Nice!!! Yeah, I love shooting 1911's so I hope noone thinks that I dont. I have fun with really anything that goes bang. But I do prefer a Glock 19 for carry everyday cause I feel I can shoot it better, and I feel that is what you need in high stress. I would like to experiment more though.
Commander size 1911 w\arched mainspring may just be a future everyday carry. I have always felt that once I can master the 1911 I will never carry anything else. I have a Kimber Desert Warrior for those that dont know, and I have about 5000 rounds through it, but that is all I have through a 1911 style gun really. And to me, and I have said something about this on here before, that a 1911 is for experts. There is alot more to do when you pull it during a situation. But you get the performance that is almost double any gun. Trigger, sights, accuracy, if you master it and carry it, it is like the ultimate defender. Kinda like a samurai to a machete. Both will get the job done but one does it with Grace.
Update:
Also I wanted to add one more thing, Mr. Bane a spur hammer and no front cocking serrations is way cooler than the more modern Commander style and the "tactical" front serrations. IMO. Retro is the way go.
