Kirk1701mv shows a modification of a GM7.5 M1911A1 model gun, a collaboration between Mule and Tanio Koba. He explains that the primary change involves removing the detonator from the barrel to convert the firearm from a firing model to a dummy cartridge specification. This adjustment allows the user to utilize dummy rounds, which are heavier and provide a more realistic weight and appearance to the model gun while it is on display or being handled manually.
Kirk1701mv got his hands on a discontinued Western Arms Colt Combat Commander Custom GBB Pistol which the he acquired second-hand. There is a bit of a mid-video identity crisis as he debates whether the piece was manufactured by Western Arms or MGC, eventually settling on it being a Western Arms customization of an MGC base. He points out specific features like the rubber grips and the Bo-Mar sights to support his theory, though he politely invites viewers to correct him in the comments if he’s just talking to himself.
