corsair, you said,
"Would Springfield's TRP, Kimber's Custom line or one of Wilson's products measure up? "
IMO, expecting a factory pistol, even a Wilson, to measure up to a pistol hand made by Marine professional gunsmiths is unrealistic. These RTE guys know what they are doing.
Regarding the MEU(SOC) 1911, from what I've read, they only have one performance requirement....go bang! everytime, without fail. They don't have to look nice, don't have to have a fancy finish(they are parkerized), don't have 1" accuracy requirments, etc. All you have to do is look at
www.1911forum.com and you'll see an occasional story about a Wilson, TRP, Kimber, etc failing somehow. But they all sure look nice and shoot tight groups. MEU(SOC) 1911s go Bang!
Pat Rogers, Gunsite instructor and Force Recon Marine, told a story on another board about his personal MEU(SOC) 1911, and it had 82,000 documented rounds through it. Also at a 5 week CQB school he taught, 21 Force Recon Marines put 15-20K rounds apiece through their MEU(SOC) 1911s, and they had 2 broken extractors(easy fix). I personally wouldn't expect a factory gun to do as well as these custom guns do. That doesn't mean the factory guns aren't nice, after all, how many of us are going to shoot as much as a Force Recon Marine? Very few of us. At the same course, 4 other Marines had M9s, and they went through seven M9 pistols, 6 lost to broken locking lugs, one with a broken safety. Beretta's (at least the one's in the military inventory) are not very durable apparently. I've learned alot just reading Mr Rogers' posts, I can't imagine how much I'd learn taking a class from him.
It's probably apparent that I find the idea of a pistol made like these IBA MEU(SOC) 1911s very appealing. It's supposed to be an improved version of the Marine issue piece, much like the Chandler Sniper Rifle is an improved issued M40 Sniper Rifle.
