Let me start by saying i do have a S&W MP9... but considering buying a neighbor's SA1911-A1. The pistol is in great shape... 1 mag... parkerized finish... standard blue plastic case... no frills, no mods or no upgrades, just plain SA1911-A1. Manufactured around 1992. 1 owner... What is the value of this gun? I'm thinking about buying it, just wondering what to offer...
