Jaybe, I don't have much experience with Red Dots, especially on handguns! I did buy a Bushnell for my AR-15, and if it works good for it, I'm thinking of trying one on my RSRH .44 magnum!
I got the Bushnell at Midway.com for about 80.00! It looks good so far, if it holds up on the AR, I'll try one on my hunting handgun! (although I think the .44 RSRH will be harder on the scope than the AR is!)
