My most recent purchase was a nice Smith & Wesson 629 in 44 mag. I've been eyeballing them for years, and knew I just had to have one. I'd originally wanted a 4-inch, but I found a good deal on a beautiful 6-inch half-lug, and so far, I'm very pleased with it. Its one heck of a shooter, and I like it a lot better than the huge Ruger Redhawk that it replaced. Even for my big hands, it was a bit too much gun, and I never did get around to scoping it.
I don't buy new guns nearly as often anymore. I feel like my collection is nearly complete, so instead of just buying things on a whim because they seem neat or interesting at the time, I'm trying to hold out for those bucket list guns I've been wanting for years.
