There is alot of personal advice for 1911's and every modern maker right now really has some quality hardware for the price. It really comes down to preference when buying one for under $1200.
I'd say get the Ruger SR1911 and enjoy the shit out of it. Chances are you'll buy a "higher quality" one down the road, while "higher quality" really doesn't make shit difference in a gun you're gonna run hard, in my opinion.
The full size and commander will really have no difference in feel other than felt recoil, so the size is really up too you. CCW, of course you'll want the commander for it size foot print, but yet again a bobtailed frame would be an awesome choice there too. Most custom places will cut the frame into a bobtail version for under $250 bucks, if you really wanted it done.
No matter what you pick out, make sure to spend the extra on good magazines. Wilson's ETM 500's are the best magazines on the market right now in regards to springs and followers. I order 3 a month on payday!
Enjoy!
