Why? For something more higher end? NH, LB, EB?
Except for my first 1911 (Kimber) which I will always keep. I have replaced all my DWs, Colts, etc
The only ones I have now are all commander or CCO size. I have a couple from Wilson, Guncrafter, Nighthawk, Ed Brown and Les Baer and I plan to get an Alchemy custom carry.
I do have other pistols such as a Wilson EDC X9 which really isn't a 1911, I also have one Rock Island because no one else makes a 1911 in 22tcm and a Coonan which is 1911ish, because you know....357 magnum!! Everything else is for a purpose such as CZ Shadow 2, Sig P210 target things like that.
Don't know if I'll ever buy another DW or some of the others as I don't like the starship trooper look of a lot of the offerings these days.
