All depends on what you want to do.

For some people "camp gun" is more of a fun gun for plunking or targets of opportunity.

For some it's protection from two and/or four-legged beasts.

Since most of my "camping" is on property I own, my son & I usually have an arsenal. On my hip and at bedside is usually is a 4" Model 66-7 stoked with handloads of Remington 158 SJHP. Feral hogs & two-legged predators are my only concerns.
