Sure you can. You can use that can on any gun you want. You can have multiple hosts for one can. Heck, you can shoot that can on other peoples guns.Any of you Mk3 guys know whether a Mk2 barrel will install onto a 22/45 grip-frame? I'd like my Mk2 integrally suppressed barrel to have the 1911 grip-angle and a push-button mag release. My suppressor paperwork includes the serial number of the gun, which is the barrel, so I just can't thread a 22/45 and swap the suppressor.
