The BLACKSIDE 45 is a handgun suppressor designed from the ground up to be the shortest, lightest weight, and highest efficiency suppressor in the most compact package possible. Highest performance is achieved with only a minimal amount of artificial environment (such as light oil). Although not as efficient dry, it is acceptable when artificial environment media is unavailable. The mount features positive front stop threading to reduce thread wear and provide proper alignment on 1911 and other pistols. The BLACKSIDE may be ordered with your choice of recoil booster thread pitch (L.I.D.) or on special order, the unboosted variant for the 1911 may be requested for the lightest and shortest possible package.

Constructed of high tensile strength aluminum alloys heat treated to Gemtech specifications, this unit does not utilize any bore obstructing "wipes" or mesh. The advanced frequency shifting baffle design creates outstanding performance. With complete suppression of the muzzle flash signature, this device is an exceptionally effective tool for tactical users.

The BLACKSIDE-45 is currently available threaded either M16x1-LH for the HK USP Tactical, M16x1-RH for the MK23/SOCOM, and 0.578-28 for the Glock 21, 1911, and other barrels. The recoil boosted (L.I.D.) version is currently available threaded 0.578-28 and M16x1-LH for the USP Tactical, and M16x1-RH for the Mk23 SOCOM.

** NOTE: Although the Sig P220 Combat TB model with factory threaded barrel is threaded 0.578-28, it has shorter barrel threads than a standard 1911(0.375" vs. 0.450" OAL). We offer a specific mount for the Sig P220 Combat to prevent the suppressor from being threaded on too far which will cause it to hit the guide rod during cycling and prevent the gun from properly cycling.. Be sure to specify if you are using a Sig P220 Combat when ordering.
