I'd probably have to go with a Springfield Pro.
What is your favorite, currently produced, civilian production Colt .45 Automatic?
OK, so the only Colt I have is the 1991 model. Other than changing the grips, I won't change a thing on it and will just keep on shooting with it.
Mine is the Wiley Clapp Commander, Just got one, I really look good with it.
My only carry 1911 is an XS Commander, early version of the XSE. My 70 series GC is in way to nice shape to carry and my 1918 was converted to a bullseye gun back in the 60's or so. I'd like a Combat Elite but I'm not paying what they want for a nice one.
My COLT 1911 is the only one I held on to.
As I switched my fighting sidearms to....traditional. DA/SA &(de-cocker)
Satisfaction in knowing that I voted for a winner, albiet its tied for 1st place.
Usually my preference , is off the beaten path.★★★★★GOLD CUP NATIONAL MATCH.
Had to vote other, I'm a serious supporter of Rock Island Armory. IMHO, the best bang for the buck in the 1911 platform industry.
I have owned a few 1911s over the years from Sprinfield Mil Spec to Kimber to various Colts. Of those, I think my favorite was the Colt Series 70 Government model 5". It was the prettiest and smoothest of them all to me.
My favorite is the 70's but I carry a Rock Island because it is a solid reliable 1911a1 and If it is ever had to be held I know it won't get lost like a friend of mine has.
Right now I have both of the S&W Series 'E' models, the 5" and the Scadium frame 4". I had a Colt MkIV 80, SA "Loaded", Para SlimDawg and a SIG P220 Elite.
If the question includes "price is no object" or "price range is $XXXX" that's a different story. I guess you didn't limit your question to 1911s either.
It may seem sacrilegious, but the current Colts do nothing for me. I do not like the way the roll marks look. And most have plastic main spring housings and triggers... And, the majority of the models have no front strap texturing...
My favorite 1911s are usually other brands
COLT G.C Trophy s.s.
2nd favorite COLT is the only other I have.
It's a 1943 Remington Rand in 90 + % condition.
My Colt Series 70 Accurized by the gunsmith at Fort Bragg who tunes and Accurized the 1911's for The Army Pistol Team. Smooth as silk.
SA Mil Spec for my favorite. I harvested a Pheasant with mine at 50 yards using a Crimson Trace laser grip setup.
I am going with my best Gold Cup National Match:
The Colt Series 70 reproduction. It's not really a Series 70 (which is fine with me) because it doesn't have that goofy collett bushing and flared barrel, but it doesn't have the Series 80 firing pin block. It's really just a plain old pre-1970 Government Model.
