I am thinking about buying one of these for my Colt 1991 A1 Government model.
Anybody have one of these? Are they worth the time and money? or just a gimmick.
 
Keep in mind that part of the felt recoil in a 1911 style gun is slide mass, by adding that to the slide you are adding to the slide mass.

Also for a compensator to give the most reduction in recoil by redirecting the cartridge gas the bore of the compensator needs to be within a couple of thousands at most of the bullet diameter.

The thing you have pictured has a bore large enough for the barrel to pass through, that's not good.

michael t nailed it.
 
The idea has been around for decades and many have been made and sold.
But, for the most part, they don't do much for this caliber.
Good technique of grip would do more, for free.
Compensators work best with light bullets and high velocities.
.45 ACP has neither, unfortunately.

The above statement is true, however do not rule out compensators on the 45 ACP.

For a compensator to work it must be fixed to the barrel or part of the barrel, there's several ways to accomplish this, those that are will work well with a 45.

When fixed to the barrel or part of the barrel all the gas is forced through the compensator and bled out the ports after it strikes the baffle plates.

The item in the picture allows a great deal of the recoil reducing gas to bleed back around the barrel into the slide as the barrel passes through the device.

I've built a lot of compensated raceguns, they all work well no matter what caliber if the compensator is designed right and fixed to or part of the barrel.
 
Years ago, one of the local uspsa competitors was bound and determined to get an open class .45 up to speed.
And he did, with a proper compensator and 155 grain bullets.
So, it's indeed possible to do.
But he eventually went with a .38 super, like most other open class shooters at the time.
 
When I was competing in the big Pin matches around the country most open division guns were 45 ACP, most shooters were making a 210 power factor or above, so there was a lot of gas vented out of those compensators.

It's true the higher PSI, the larger the volume of gas vented through a compensator, the more the recoil impulse is changed, fast light bullets give the most in PSI and volume.

I finished my Pin shooting career shooting a 40 S&W racegun making 210 power factor and that baby vented gas like a hot rod 38 super and that's what the recoil impulse felt like.
 
This device seems to function on a different principle from barrel compensators,
by adding mass to the slide more energy is absorbed on recoil so less is then transferred.Also by placing the weight at the muzzle,flip would also be decreased.Gas redirection is probably ineffective,it probably works but it may not be worth it.
