I'm looking for a compact rifle that will fit in my back pack when hiking around. I will be crossing freeways and walking thru a couple of small towns so I don't want it to be noticable. I would also like it to shoot pistol rounds 357, 44 or what ever, but not .22 rounds. Its not one for SHTF but one for protection after we stop to camp. Its a 5 day casual hike nothing to serious. Can anyone recommend a rifle for this.
