A few years ago I got rid of all handgun’s not using 9mm or 357/38. It makes life much simpler.
I am kind of thinking on a Walther PPQ M2 5” long slide. I wish the Kel-Tec Sub 2000 took their magazine or anything in a long gun took their magazine.
I try to stick to a few cartridges. Makes life simpler. For other people, they want one of everything, but I am like you. I want it simple. I think all mine are .45 ACP or 9mm, not counting .22 LR. And the price on it is reasonable. I would hate to pay the premium on .380, 10mm, or .45 Glock or some such.
