Well heck. I guess since this is a new thread, I can come up with a new list. Here are 6 Ruger revolvers that I, personally, cannot live without, in no particular order:
1. Ruger Blackhawk 45 Colt/45 ACP Lipsey's Flattop Convertible - 5.5" barrel. One of my all time favorite revolvers.
2. Ruger Birdshead 45 Colt (Don't have one yet, and my life is the lesser for it. One day I'll have one, and together with the Blackhawk I will have the baddest-a$$ old school CCW rig ever.).
3. Ruger GP100 - 4 inch barrel. Don't get me started on how much I love my GP100. I'll go on for days.
4. Ruger GP100 - 6 inch barrel (Don't have one yet, but need it badly for my glove box.)
5. Ruger SP101 (Don't have one yet, and my life is the lesser for it).
6. Ruger Blackhawk Flattop 44 Special. (Alas, another one that I need to own.)
