This. Purchased from DCM (CMP now) in 1962 for $25.00. Ithica slide on a Colt frame (U.S. Government rebuild). It now resides in my gun safe with 8 other 1911's.
I like several, the S&W, 645, that I own, the S&W, M&P, that I will own, and the S&W, 1911, that I too, will own ..... I also like the Springfield XD.
Of course, the Original, Colt .45 .....
I know I'm supposed to have some uber-exotic mega-expensive Night Elf Mohawk Tactical Cup Operator Ranger Model Terminator Special but by far my best shooting and favorite is the big ol' fat G21.
I'm going to be in the minority but I will say it anyway. My favorite .45 is undoubtedly the Jericho 941. Its a heavy metal frame weapon made in Israel and shoots like a dream. I would not want to use it for daily carry due to the weight but its a tack driver.
