This compensator from REVO-GEAR is intended for use on the S&W 929 revolver. If is a compensator that really works much better that the device that comes with the gun. It is a bolt on part and can be easily removed.
This comp also fits on the S&W 627-4 chambered in 38 Super.

The comp woks very well. Very noticeable reduction in recoil over the factory single port conp.
Fit & Finnish are what is to be expected from RSC.....PERFECT IN EVERY WAY. I'm running them both 1st on a S&W 929 9MM & A V-COMP 38/357. The comps will preform better with lite bullets going fast to very fast. Also powders that produce a lot of gas volume will make comp work more efficiently. Try to stick with thick plated bullets or Jacketed without exposed bases to eliminate the lead fouling that WILL accumulate on the compensator. You'll be surprised how fast it builds up & is a bear to get off. I've gone as far as coating all the compensators before shooting and after shooting with raw lanalyn.. It helps a lot but doesn't eliminate it. 2nd. On The v comp. Stick to hot lite 38spl & 357 you can really feel the comp working. It's Great that RSC is making a great product for 2 amazing revolvers.
