Quick Overview

Gemtech Blackside .40S&W Direct Thread Suppressor

* Required Fields

Gemtech -


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. Extensive testing has demonstrated that a recoil booster is not necessary for many host firearms, including the 1911, Smith & Wesson M&P45, and the majority of the difficult to cycle full-sized HK USP Tactical. At extra cost the Blackside can be ordered with a recoil booster (L.I.D.) or one can be retrofitted later. The upgrade charge of $210 is the difference between the boosted and non-boosted version.

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. Extra pistons to allow a change of threading may be ordered separately for $135.


The Blackside suppressor in .40 caliber is currently available for a number of handguns designed for the .40 S&W cartridge. Specifications are similar to the .45 caliber version. However, by default, all the BLACKSIDE-40 suppressors incorporate an integral L.I.D. (recoil booster), while the .45 caliber BLACKSIDE-45 does not. The Blackside-40 suppressor is threaded 9/16-24 (2A). On special order it can be supplied threaded M14.5x1-LH for the HK USP Tactical in .40 caliber. Extra pistons to allow a change of threading may be ordered separately for $135.
