A few of the things I am actively looking for and will buy if the opportunity presents itself.
The Kel Tec PMR-30 (a .22 Mag semi-auto with a flush fitting double stack 30 round magazine).
The FN 5.7 pistol.
Neither are brand new, but fairly new and different. Why do I want them ? Because I think they are cool. As I said before, I have umpteen S&W revolvers and more than a half dozen 1911s. They are somewhat boring to me.
I just ordered one of those 80% "Glock" frames to finish.
Why ? Just for the heck of it. I own a half dozen Glocks in 9mm. The 43, the 26, the 34, two 17s, and a 17L. I don't own a 19. So, rather than just going out and buying a 19, I figured I would make one. Because, why not ? I couldn't care less if it costs me more or less than just buying one. I want to do it.
I am definitely not one of these guys that views guns as tools. I don't need some specific reason or purpose to own a gun. I buy and shoot guns because it is fun. Part of the fun for me is trying new things. FWIW: I don't care about hunting or the defensive use of firearms. I might hunt. I might carry a CCW pistol. But those purposes are way, way down the list of why I might buy or own a gun.
