Since nobody mentioned it, I will. Of course it's not new.
I have an old High Standard R-100 Sentinel. Probably not as smooth as a S&W, but not bad at all. The fact that it's a nearly 60 year old revolver and mine has the requisite number of scratches, it's a fine shooter. Might also look at the Double 9. Same action, just looks like a western style revolver.
The Sentinel series looks more like a police style. Whatever. Probably a $200 gun that I don't worry about! Assuming, of course, I can find ammo for it. So far, so good.
