ASP .45

Quietest & Lightest 45 Pistol Silencer on the Market

*Silencers must ship to an FFL/SOT; we can help you find one in your area. There will be a 10% restocking fee for refunded orders.


The ASP is 1.5″ in diameter by 7″ long and as such, is one of the smallest .45 pistol silencers offered. Weighing a scant 5 ounces, everything but the insert is aluminum to keep weight to an absolute minimum. The finish is tumbled and matte anodized.

This silencer will provide excellent performance on the HK USP Tactical and MK23 SOCOM, on standard-length 1911 variants, some Sigs, the occasional carbine, and even Beretta 92Fs. The ASP is intended to cycle on .45 ACP pistols using full-powered ammunition and 230-grain bullets. We recommend the brass-cased CCI Blazer ammo as a budget-conscious, full-powered round. The can will continue to perform well using weaker rounds and calibers, but the firearm will not cycle in most cases due to a lack of sufficient recoil being generated by the round.

The insert system allows you to mount the ASP .45 on, and effectively suppress a staggering array of pistols. All of the inserts are made to shoulder on the muzzle except for the ATAS 1⁄2 X 28 and ATAS 5/8 X 24, which are made to use the shoulder on the barrel.

Each silencer comes with one insert and an insert wrench.

The ASP .45 is intended to be used only as a “wet” silencer on pistols; an ablative is required to achieve the best performance. While we provide a bottle of wire-pulling gel with the ASP .45, other ablatives may be used if so desired. On rifles, the silencer can be used dry if desired. On a 5.3″ Glock 21, using 230gr brass case Blazer .45 ACP, the ASP will average 125dB.
