For me it was revolvers to begin with. That was about 40 years ago. I had several S&Ws and Colt revolvers. (It's been so long ago that I can't even remember the models.)
Then I was on an Auto Pistol kick for several years. I bought a Springfield 1911A1 and had it for awhile then sold it. Then I bought more revolvers. I was into the cowboy action thing until I realized that unless I reloaded I just couldn't afford it.
Then I was all about CC guns. I bought a S&W642 and had it for awhile then sold it and bought a Ruger LCP. And now, I wish I would have kept the 642.
So now, I'm very ammo sensitive. I sold my Ruger Super Redhawk and kept my Ruger Blackhawk .357 simply because I hated lugging around that heavy monster. But, now I miss it.
So, I just bought a S&W 28-2 and love it. I'm still buying autos but I think I'm going to weed down my considerable collection to just a few that I absolutely can't live without.
You'd probably be surprised to know that one of "those" guns is my old, trusty Ruger P89.
