Pretty much anything from Ruger.
I love their revolvers, from the old Six series, to single actions, to the LCR. And I have/will have representations from almost each one of those product lines.
I bet my life on an LCP as my backup gun nearly every day.
I want one of their 1911's, a 77/357, an American, etc... etc...
Pretty much anything they make, I would buy. I have a major crush on them.
