Hello, I have a 9mm Smith and Wesson model 915 pistol. I've had it for a couple of years now. It is in great condition (90-95% bluing) with a few blemishes from normal wear and tear. It came with, what appears to be, 1 factory hi capacity magazine and the Smith and Wesson "box". It also seems to like just Remington ammo, which concerns me. I am just trying to find out how much it would be worth because I have been thinking about selling it and using the money from it to buy a Ruger Mark III. Any input would be great, Thank You!
