I like to add a pistol, shotgun, or rifle (.22) that I don’t have in my collection, which really isn’t all that big. The last pistol I purchased for instance, was a S&W 422. I never knew it existed until one showed up in the used case at my gun club. I looked it up that evening and bought it the next day. It looked like a S&W Mdl 41 at first sight, and then it wasn’t. It has turned out to be a very accurate pistol. And it was made on my wife’s birthday in 1996. She was made in 1946 .
Some of them have required a little work, cleaning, etc., but that is always a learning experience.
