Thanks for the wealth of information. I got to hold a SA TRP this weekend! (didn't get to shot it) Man that is one really nice piece of machinery! I told the shop owner that I was interested in collecting but wanted something I could shot every now and then. Like the advice that I received here, he said TRP was probably the way to go. I did ask him about the SW 1911, he stated its nice if you want a preloaded 1911, because SW loads them with after-market sites and lasers. Most collectors tend to want to load them their-selves.
Where I haven't ruled out the SW, I think for my 1st 1911, it will be the TRP. I hear nothing but good reviews. SW has, in my opinion, the polymer market cornered with the M&P so much so, that it has the potential, if it hasn't already, to beat out Glock. Springfield's TRP appears to be a top ranked 1911.
I'll keep you posted!
