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 compatable with subsonic .300 BLK. It uses the SilencerCo Alpha accessory platform and ships
with the Spectre 9 Piston Housing Assembly and tools included.

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 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.
