I'm gonna be careful wishing for particular firearms. I've always wanted a Ruger Alaskan. I made the comment one day that if someone built an Alaskan in 500, I'd buy it. Damn you S&W, I'm still saving up.
Dang it. If you only wanted the 4" model I could help you out. :-)
My firearm wish list right now is mainly that I wish I had my own range to shoot my firearms on. I got spoiled going to my friend's house in Slaughterville any time I wanted and using his range. He sold the property a couple months back and I'm having serious seller's remorse. ;-)
