Here's another suggestion but first, here's one reason for a "one gun" thread: you only carry one gun. For those of you who carry more than one gun, just go to another thread. This won't interest you. Anyway, it's always a good topic.
I didn't think of this first. I don't think I have ever thought of anything first. One writer who seemed to know what he was talking about and actually had a reason to have a gun thought he had found the perfect handgun--for his circumstances. His pick was a S&W Model 66 with a 2 1/2-inch barrel. He lived in Florida. It didn't rust and was powerful enough for anything in Florida and it could be loaded with a variety of rounds without changing the sights. Sounded pretty good to me.
I had at some point a S&W Model 65LS, which I thought was even better. It had a three-inch barrel, under-lugged even, and of course fixed sights. I've usually preferred fixed sights. I also owned a Model 10 with a three-inch underlugged barrel, too, but I only mention that as a matter of interest. Well, anyhow, although I thought the gun was a delight to shoot and was a perfect size, it really wasn't the easiest thing to holster for concealed carry purposes. Still, it had a lot to recommend it. And just like Webley-Fosberys, they don't make them anymore.
