Simple, you don't. The calibre is too large for the round to be chambered, for using whatever Glock that is I recommend you use 9 x 19mm otherwise your going to have to stretch your gun, whatever kind of Glock that is, I'm sure it's a 23 which means it uses 40 s&w, otherwise it could be G40, but the barrel is too short, it could either be a 17 or 19. Which means your aspose to use 9mm indefinitly.
