Just to clarify it doesn't have to be a weapon you own or owned, just fired.
Anyway, here is my list (not in any particular order):
1. M-16 (all sorts of them)
2. AK-47 (a couple of models)
3. Uzi
4. Glock 28, Glock 26, Glock 17, Glock 19
5. Shotgun (double & single barrel with & without pump action)
6. M-14
7. SIG-Sauer SSG2000
Actually there were a few more, if I'll remember them I'll add them later.
