does a compensator fit any 1911 or specific models only?

[1858rem]

i have seen a few compensators for 1911's, im not really interester in the compensator itself, but how it attaches to the pistol.... i have a 5" RIA 1911 and there is absolutely no room to screw anything onto the end of the barrel, so does that mean its only for commander 4" 1911's with a 5" thredded barrel only? i am confused

As I understand it, typically a compensator will also come with a longer guide rod which acts as your attachment point.

EDIT: Which just goes to show that, on fancy-pants competition guns, I have no idea what the heck I'm talking about!

Here's an old thread that talks about it, http://www.thehighroad.org/archive/index.php/t-127036.html

Any good comp will screw onto the barrel. They do not attach using the guide rod.

Here is a good link to the different types of comps: http://www.gansguns.com/

For a 5" gun, most likely you will need to have the front of the slide milled back a little. Barrel threaded. You will also need to have the slide milled to put a reverse plug installed. From experience I would suggest a cone compensator.

Do a Net search -- there are/were companies makeing a 1 ps. barrel with the comp already attached --- simple drop in unit.


EDIT --- these were NOT "cone type" but used a brl. bushing.

You get what you pay for. Nothing is drop in on a 1911, especially a barrel.

Well, there are also the barrel-bushing comps.

They are not very effective but if what you are after is Kewl Factor, they are cheap.

i was just bogggled as to how they even fit since my 1911 has no room for......anything.... at the end of the barrel


noone makes a 6" for a 45 auto 1911 do they(not custom)

There is a 6" 1911A1 .45, it's called a Citidel, same as a RIA. Made by Armscor. If i remember right they run about $700.to $800.

Here's a challenge

I've seen plenty of compensators appearing on guns, but few actual measurements of their effectiveness.

I challenge anyone to put up measurements of the effectiveness of a given compensator on a .45 pistol.

My GUESS is the gas pressure at the muzzle and the size of the bore both mean that a comp is probably going to be an expensive ornament.

any takers?

Good thing you didn't say youl'd bet money on it !!! LOL

In the mid-1980s , Gunsmith/Top Competitor Bill Wilson and John Shaw were the first people to start useing "compensators" in IPSC and Bowling Pin matches.

In the USPSA monthly pub. ---- there has been more then one test to compare the effects of brl. weights/ports/comps ---- one I remember , was a test where they used a Ransom Rest to hold the gun and mounted a pen on it to record the amt. of muzzle rise.

Another very early test was to put [ X ] amount of tape over the comp/ports --- if it blew off four wraps of tape , it was a better comp then one that only blew off two etc.

Here is a photo of my old Jim Clark Sr. built Pin-Master;


This is a Gen II ---- better then the Gen.1 at reduceing recoil and muzzle rise.

I used 200 gr. handloads in IPSC and the Power Factor was 175 at the time --- for 2nd Chance Bowling Pin matches , I used 185gr. JHPs at about 1000fps to knock the pins off the table.

If you used 230gr. bullets , you would see more amount of of muzzle rise then the 185/155 gr. at higher fps ----- the more gas you have , the better the ports/comps work.

The early comps worked so well , they made the Match Directors start a seperate class for them and that is why , still to this day, we have a Open/Unlimited class and a Stock or Production class.

BTW --- EVERYONE that has shot my Pin-Master after shooting the same ammo in my stock Gold Cup said there was less muzzle rise and the recoil felt "softer" to them.

A well designed "Comp" is NOT a gimmick ---- look at modern battle rifles , tanks , etc. -- they ALL have some kind of "comp" on them.
