I've always owned revolver handguns and don't know anything at all about auto's but a friend of mine has a Ruger P90 45cal that is new in the box that he said he would sell me for $350. I've never owned an auto in fear of it jamming but always told myself if i ever bought one i'd go ahead and spend the money and get a Berreta or a Glock. Is the Ruger P90 a good operating auto handgun and is that a good price? Thank You!
