Abstract

A retainer for securing a silencer to a barrel of a handgun is disclosed. The retainer includes a counter-attachment on the barrel of the handgun for attaching the barrel to the retainer, and also includes a forward part for receiving the silencer. A bore extends through the retainer for receiving the counter-attachment, and the inner profile of the bore and the outer profile of the counter-attachment define at least one gas expansion chamber between the counter attachment and the bore when the counter-attachment is disposed in the bore. A lock on the retainer engages a collar on the counter-attachment, thereby releasably securing the counter-attachment in the bore.
