I teach both civilians & security officers shooting basics. The under 30 crowd has to have a 9MM semi-auto stocked with as many rounds as made. This applies to both guys & gals. I always suggest a revolver in .38 Special for casual shooters, but few listen. At work the .40 Glock has become the standard & is a great caliber. Had an inexperienced female S/O trying to qualify who powder burned her a$$ & put a round into the range floor last week. I frequently carry a .357 SP101 when in the woods or as back up in my truck. Used a .45 in the military & recently purchased a Remington. Both the .357 & .45 will stop most 2 & 4 legged critters with the right ammo.
