Looking at a used SA GI 1911 45 on a local hunting forum. Seller claims the gun was bought in 2006 but only has 300 rounds through it. I'm looking to get a good 1911 for under 700 until I can add a better quality one to my collection. Is $550 a good price for this and what can anyone tell me about this model? I couldn't find very much material or reviews on it. Thanks!
