When transporting your firearm, keep your threads crisp and protected with a thread protector.Careful not to cross-thread, simply twist the thread protector on the end of your barrel to prevent dust and debris from clogging your threads when no silencer is in use..578" x 28 is compatible with most us-made 45acp.
