I have some "go to" guns that are seemingly perfect... thinking modern common handguns (Glocks, Sigs, XDs, M&Ps, etc.) and long guns (AKs, ARs, FALs, pump shottys, etc.)
Then I have a tier of guns that are less than ideal, but still great guns that I'd rely upon. (SKS, SxS shotguns, 2nd tier handguns, rifles in handgun calibers, handguns in rifle calibers, etc.)
Then I have a tier of guns that are effective, will work, but would not be my top choices despite the fact that they'd get the job done. Thinking C&R guns, lever and bolt guns, etc.
