Yes, I've also heard gankstas call a shotgun "Da Gauge" and a pistol a "Gat".
I kinda prefer 40's slang.. like ROSCOE and HEATER or the Old West HOG LEG lol.
A pistol is a Glock. Anything that makes bullets come out of the front is a Glock. I had one guy tell me he wanted to buy a Glock and point to a rack of shotguns.
Considering the current administration, I think we will soon see the F-22 Glock, the KC-45 Glock, the M4 Glock carbine, and, of course, the USS Glock.
