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 Basilisk Compensator for the Military Armament Corp MAC 9 DS 1911, is a frame mounted compensator with two large expansion chambers that redirect the gas flow into two large top ports and four angled side ports which dramatically reduces muzzle flip and felt recoil.
This 50 state legal compensator is made for unthreaded barrels and is anodized black. This compensator has an ambi thumb ledge lower with horizontal serrations that match the horizontal serrations on the slide release and thumb safety, which creates a cohesive aesthetic.
We designed our thumb ledge lower around the X300, other brands of lights have longer mounts and will sit farther forward.
Adding a compensator to a pistol reduces muzzle flip and recoil energy, as a result recoil spring tuning will 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.
