i want to purchase my first semi-auto handgun. i have a taurus 85ss, so i want both a more substantial round, and either a medium framed or full-sized weapon. i think i would like to keep it to a 9mm or .40. a .45 might be an option later. i am also interested in a stainless weapon. so, to recap: 9mm or .40, stainless, medium to full sized, and the kicker......the price should be no more than $600. options?
