Colt M1991-A1 commander vs. 1911

[Smiddy]

Simply put what are the differences between the two?
Will parts such as grips, triggers, sights, slide release, safety, etc.. Be interchangeable?
What is the best website for parts and accessories besides midway and brownells?

Thanks

About 3/4 to 1 inch..........

 

4" commanders have cone barrels and a different recoil rod. That's about all I can think of that's different in my Kimbers.

Most 1911 parts are going to need some fitting. As far as what parts are similar in the Commander and Govt. Model it will depend on if they are a series 70 or a series 80, some sights are a different  styles or cuts (basic models have a GI.Style Rear and a Post front while others have Novack Cuts for the Rear and dovetailed Front's) as stated in one of the posts above check out that site or this one 1911addicts.com   they both have a wealth of info.

The frame of the government (5"), commander (4.25"), and champion (4") are the same.  Those guns have a full size frame.  It's the compact size frames that are smaller.  Like others have stated, some parts require fitting, but many do not.  Grips are interchangeable between the full size frame units

Most parts for a 1911 will fit the 1991 series of guns. Many will require minor fitting for the best performance and safety. Remember that Colt commanders have a 4.25in barrel, and a standard 1911 will have a 5in barrel. other than that they are essentially the same. All 1991 versions are series 80 style with a few extera parts in the trigger system for a firing pin block that the older guns don't have.

 

The 1991 was the base model and the first ones were parkerized rather than blue or some other finish. They also all had stake on front sights with a wide tenon. This make front sight replacement a bit more difficult.

 

I really like commander length guns to me they have a bit better balance.
