I have a beat-up first edition of Bill Jordan's book on gunfighting, "No Second Place Winner" boxed up somewhere where I can't easily retrieve it, so I'm going to have to paraphrase. He advocated for a then non-existant gun for concealed carry; a snub-nose revolver chambered for .22 WMR. I was surprised when I first read that, but the man was knowledgeable in ways I never will be. I started out with a Glock model 27, which is being converted to a model 26. Being 61, the thought of a .22-caliber-something sounds appealing. As a previous poster wrote, growing old is not for sissies...
