1911 compensators

[ms6852]

Is a gunsmith requried to install this compensator and will it fit the 1911 Sprinfgield G.I. with a 4" barrel? I also have a fullsize and was curious as to how they work. So this particular one on CDNN.

If the gun already has a bushing, then a gunsmith isn't required, but it's a waste of money.

For comps to be effective, they need to have restriction at the front. IE; a hole just large enough to allow the bullet to pass thru. This creates a build-up of gas pressure as the bullet "seals" the exit, thereby forcing the gas to escape out the ports. This would dampen muzzle rise.

Those compensator bushings allow all kinds of blow-by as the bullet exits, thwarting any attempt at muzzle rise control.

Thanks for the quick response. I kinda thought anything that cheap would not be that good. Just hoping.

I have tried a few different designs and any improvment i think i felt was probably just in my head.

Like many accessories for guns, it could be seen as useless but its your money. I have a few and on some 1911's it add's to the style IMO....

who really needs 3 flashlights, a green laser, a red laser, strobe, scope with a 45* canted red dot, glass breaker on the tip blah blah blah. Its what you want to do with it.

Some years back I had one of the comps you are looking at. I put it on a comander, It did work but not nearly as well as a barrel mounted one. I think it lasted about 200 rounds and the lip sheared off and it was junk. I would say buy a barrel, one that you can attach a comp to and you will be happy, Or go to magna port, and check them out I will say that I am very happy with the work they did on my 586. I will be sending my 642 to them soom.

Can you/is it worth it, to both magna port and put a compensator on? Or would the gas escaping from the port pretty much render the compensator ineffective?

Comps work best with a hot load. They need a certain amount of gas to function correctly. While I've never known someone who both ported and comped a gun, I don't think it would be workable.

I'd check with Chuck at Shooters Connection, or on the Brian Enos forums. You'll get the right answer, fast.

It's very workable. It's also very loud.

Friend did the "Hybra-Port" (much bigger holes than Magna-Port) in addition to a compensator on his .38 Super. He ran hot loads and it worked great. He had to add more powder to make up for the velocity loss, however.

Well I would say that you do not need hot loads to have it work, In my 586 I run handloads of 38spl. that are light and it still works. the gas that is let out is after the bullet passes the holes , There was no diffrence in speed using a crony using a revolver with or without magnaporting.It pushes the gas up and then the barrel is pushed down.Some autos may have a problem with cycling as the gas is vented off. I shot steel plate many years with 38's and never had a problem. As to putting both on a barrel, I see no reason to do it as you have one allready there. a comp adds lenth to the barrel, so for ccw that may be a problem.
Magnaport told me that there is no more noise. I don't believe that, but I may be wrong, I can't measure the noise. There is alot of flash that comes out the top holes and may be a problem in a SD enviroment. Night blindness.
Shooting lead threw the gun will lead to a build up around the holes. But if you shot jacked bullets there will be no problem.
I love the magna port and would highly recomend it to all.
