Differences Between a 1911 and a 1991 ?

[Caneman]

A Colt .45 ACP is the next gun to get on my firearms bucket list... what is the difference between a 1911 and a 1991?

For those wondering what the difference is between these pistols, the fact is there really is none. Back in 1991 Colt decided to market an economy version of their basic Series 80 Government Model. The polished blue was changed to an all-matte parkerized (later matte blue) finish, checkered rubber grip panels were used, and the serial number sequence was a resumption of the ones originally given to US military M1911A1 pistols. The resulting pistol was cleverly named "M1991A1", after the year of introduction. Mechanically however they are the same as any other Colt Series 80, 1911-type pistol. Around 2001 or so Colt upgraded these pistols with polished slide and frame flats, nicer-looking slide rollmarks, stainless barrels, and wood grips (blued models only). The newer ones are commonly called "New Rollmark (NRM)" pistols by Colt enthusiasts, to differentiate them from the "Old Rollmark (ORM)" 1991 pistols. The earlier guns are easily identified by having "COLT M1991A1" in large block letters across the left face of the slide. The NRM Colts will have three smaller lines of text saying "COLT'S-GOVERNMENT MODEL-.45 AUTOMATIC CALIBER", along with Colt's rampant horse logo.

My buddy Joe has an ORM version of the Officer's model (3 1/2") and I'd post the picture of the target if I still had it, but at 20 feet I put five rounds in the same hole. The sixth round was barely off by about a half inch. I should really start keeping pictures of my targets. I'm beginning to get a lot better with the 1911. It could have been the ammo too. I used this PMC 230gr FMJ stuff the range had. NIB factory ammo. Usually I run Winchester 230gr FMJ.

If the 1911 is your choice, you don't necessarily have to get a Colt either. There are many alternative which offer more options at a better cost. Kimber, Springfield, Taurus, Rock Island Armory, ATI, the STI Spartan 9, Smith & Wesson, Citadel. I've owned a Rock Island and currently own a Springfield. Both are great 1911s.

About 80 years,

Sorry, I just had to say it.

There is no difference, as shown in hoggers quote. I think it was just a marketing ploy by Colt. I have Rock Island, Taurus, and Citadel 1911's and they are all very good alternatives to Colt at a fraction of the price.
