Might as well ask a golfer if he could only carry 3 clubs in his bag, or better yet, ask a fisherman which three lures or a fly fisherman, wet or dry, which three flies, and store bought or handled made. So for your question, I’ll respond in kind, what job do you intend for that gun(s)? Self defense at home isn’t the same as concealed carry in public, is not the same as water birding , is not the same as pot hunting is not the same as dangerous game hunting. There are pistols that are acceptable for grizzly out to 100 yards and rifles, axe guns , in any caliber cut down on both ends. And we haven’t even begun on the bullets: FMJ, HP, soft points, round points armor piercing, tracer, lead-tin alloy. However, the most important element in gun selection is behind the gun not in front of the smokey end. The gun that fits my hand, cheek and shoulder may not fit you. If it isn’t comfortable you won’t do your best. Unless we are only talking about fun shooting on a sunny day, the details make the difference in bringing home dinner or not coming home at all. The last point I’ll make is about training and that concept includes so much more than just shot group. With a ten dollar club or a 1000 dollar club, my golf card are going to look the same because I haven’t picked one up since I shipped to the Northern Tier. When you are satisfied with your shot group, run 40 yards, stop and shoot; now turn off the lights and empty your piece at the target. Now face away, then turn, acquire and neutralize 3 targets. And by the way did you maneuver to clear the area behind your point of aim to avoid endangering others needlessly?
