1911 full profile compensator

staind460
i have found a 1911 gov length full profile comp, barrel and bushing that i am considering installing on my springfield armory mil spec (not GI) 1911. the catch is the barrel that comes with the comp is a 5.0" throated barrel with a polished feedramp from a colt combat elite.

will this fit on my pistole even though mine does NOT have a throated barrel?


also does anyone have experience with full profile comps? are they affective, to heavy etc.

    Hello I would like to be of some help but one of the terms you use has me confussed. The throat of a barrel is the section just in front of the chamber. As a 45 ACP head spaces on the front of chamber I have never heard of a "THROATED"? 45 acp barrel.As far as a comp weight is a plus and neg.The weight holds the gun down but also makes it harder to hold up.Some Comps work very well and others just make more noise. What brand do you have?If this is the type that takes the place of the barrel bushing then it should work on your gun but If it is the type that threads onto the barrel then the only way to tell is to install in your gun . quote:"PRAISE THE HARDBALL GUN"

    It's not clear in your post, if the barrel is "Ramped", i.e. integral ramp that is manufactured as part of the barrel. These "Ramped" barrels require that a mortice be machined in the receiver of the pistol for them to function.

    If the barrel your inquiring about, isn't "Ramped" my 2 cents is that it will fit and function OK on the SA.

    thanks for the quick info guys.

    the add for the barrel said it is throated so i am not sure if the add is incorrect or what. as far as the ramping it will not work in my piece since there is no mortice cut into my frame

    to be quite honest . . . i know it sounds week but i am going for the look of the two .45's from the new punisher movie. but at the same time i am looking for legitimate accuracy and function out of my normal old 45

    THe "throating" of the barrel is to allow for longer OAL of the cartridges to keep down pressure. My 40S&W 1911 will take a 1.26" COL., rather than the standard 1.13".

    HELLO Richbug I DON'T know anything about a S&W 40 however a 45ACP headspaces on the mouth of the case and If you load more than about .020 of an inch longer than factory some bullet designs will not fit inside of the MAG.So we would not want to throat the barrel. quote:"Praise the hardball gun"

    There is definitely some confusion of terminology going on here.
    "Throating" a barrel usually means to enlarge the throat area of a barrel...this is the little lip leading up to the chamber. Generally, the beveled area is widened a little and polished up for better feeding.

    A ramped barrel has a large ramp built into the barrel as opposed to the thin lip on a standard 1911 barrel. This is generally done to have stronger, fully supported chamber, especially for the higher pressure cartridges like .38 super and .40 S&W. It requires a chunk of the frame be milled out.

    "free boring" a barrel means to machine out the area ahead of the chamber slightly such that the rifling starts further down the barrel. This is NOT just reaming out the chamber to a longer length! The idea is to allow seating bullets out longer. If you bullets are seated out long enough that they engage the rifling, you can get serious pressure spikes when the primer goes off. Sometimes, people need to do this so their long-loaded bullets will even chamber. So, you enlarge the free bore area (distance bullet travels before engaging the rifling) to relieve pressure.

    I'd worry more if it's a Bull Barrel or one of those bushings. If it's a Bull Barrel just have a reverse guide rod plug installed then fit it to the slide and go. Or if it's a bushing then slap it in and go. I imagine it's the ramped bull barrel that's throwing him off in the wording. I could be wrong.
