A guy I work with is selling a ruger 44 mag pistol. It has scope rings on it but no scope. He isnt sure what he wants for it so I thought I would ask you all what a good price would be ? It is in excelent shape. $400-$500 ?

The price sounds like it's in the ballpark, but make sure you like the trigger pull. The Rugers are solidly built guns, and will last a long time, but the trigger pull really turned me off when I compared it to a standard S&W 629 in 44mag.

All rugera are more strongly built than ANY smith. Design fact-like it or not smith fans. if you can get it for right price-jump on it.

I'm assuming you're talking Revolver?

of course rebel

That does not sound bad for a Ruger that hasn't been abused!
I got a 2 month old RSRH, with rings cheap scope, shoulder holster and a box of Cor-Bons for 400.00!
I had a friend run a check on it just to be sure that it wasn't hot at that price!
I also looked it up by serial number on Rugers web site, that is how I found it was only 2 months old!
