Wayne, the Beretta pictured is the .22LR I bought 25+ years ago. I bought 2 more 5 or 6 years ago at an auction; 1 each of the .22 & .25 cal. NIB. I bought them for the gun make/model/design vs. the caliber. You cannot beat the palm sized .45 cal. design in such an easy carry, familiar design. The best EDC defensive gun is "the one that you shoot, WILL carry & have on you." Four-five fast shots, still leaving you 3 in reserve absolutely will get someone's attention. One of these (her choice) will be one of the 3 that will go with my daughter in a month when she moves 1000+ miles away.
Billy, I'd like to offer my non-expert assistance as you ease back into hunting & shooting. I have my Blue Ridge farm woods and 1000 yard (+) range as a good place to pursue your quest. My back/spine has retired me & I've added those 2 pursuits as part of my own retirement plan. Certainly the gun, knife museum & shows you list are on my own list as well.
What a retirement plan!!!
