US Patent 10969188 Pistol slide-mounted suppressor

A firearm suppressor configured for coupling to a firearm with its stock barrel bushing removed. The firearm suppressor includes a barrel bushing feature, a recess, and a release. The barrel bushing feature duplicates the barrel bushing of the firearm, which constrains the movement of the barrel of the firearm. The recess is positioned below the barrel bushing and is configured to receive and retain a cap of a recoil spring plug of the firearm. The firearm suppressor is coupled to the firearm when the cap of the recoil plug of the firearm is retained in the recess. The release is configured to press against the recoil spring plug of the firearm. Actuating the release pushes the recoil spring plug of the firearm away from the firearm suppressor, such that the firearm suppressor is removable from the firearm in the same manner as the original barrel bushing.
