This frame compensator is compatible with the current production (Gen 3) MAC DS 4.25 and MAC DS Comp 4.25. Gen 3 MAC pistols have windows cut in the slide serrations and they have a full length frame, if your pistol does not have these features you have a Gen 1/2.
The Underworld Arms Cerberus Compensator for the Military Armament Corp MAC 9 DS 1911, is a compact triple port frame mounted compensator with superb efficiency and performance. The Cerberus uses concave gas diverters at the front wall of the expansion chamber to route gas into the two upward angled side ports and the top port. By using this concave diverter the gas retains more of its energy as it is redirected and more gas is trapped and redirected into the ports. The side ports are angled up at 68 degrees which creates a 44 degree arc of gas venting.
This 50 state legal compensator is made for unthreaded barrels and is anodized black. This compensator has a standard lower rail, for a thumb ledge lower rail please see our other listing.
Adding a compensator to a pistol reduces muzzle flip and recoil energy, as a result recoil spring tuning may be required and we offer a spring set for this purpose.
Compatible holsters are available HERE
This compensator increases the dimensions of the firearm so it requires a dedicated holster like the ones we make, or a universal holster such as the MSP Tier 1, and the blackhawk omnivore light bearing.
