SilencerCo Spectre 9

SilencerCo Spectre 9 Details

The SilencerCo Spectre 9 is a full-auto rated, all-titanium 9mm suppressor built for pistols, subguns, and PCCs. It weighs 3.9 oz and measures 4.76" long with a 1.37" outer diameter — compact enough to run in most suppressor-ready holsters and light enough that you'll barely notice it on the gun. Constructed entirely from Grade 5 and Grade 9 titanium, the Spectre 9 is also compatible with subsonic .300 BLK. It uses the SilencerCo Alpha accessory platform and ships with the Spectre 9 Piston Housing Assembly and tools included.

• 3.9 oz total weight; compact enough for all-day carry setups and running in suppressor-ready holsters

• Full-auto rated; one of very few 9mm suppressors verified to run on a full-auto Glock platform
• Compatible with 9mm and subsonic .300 BLK (see caliber note below)

Mounting System Overview

The Spectre 9 uses the SilencerCo Alpha accessory platform. The Alpha direct thread mount threads directly onto your barrel and uses the included Spectre Tool for tightening — the mount also features internal wrench flats to address barrel spin-off during removal. The Alpha ASR mount provides quick-attach/detach via a secondary locking collar and requires a compatible ASR muzzle device. The Alpha piston mount enables use on threaded pistol barrels; pistons are sold separately in various thread patterns. The 3-Lug mount is a push-and-twist fast-attach option designed for 9mm pistol applications. Use only 9mm 3-Lug muzzle devices with the 9mm 3-Lug mount.
