I'm in the market for my first 1911. This will be my second gun purchase, I have a Ruger GP100. I am trying to decide between the Rock Island Armory 1911.... this one specifically.....Rock Island Armory 1911-A1 Tactical .45 ACP 5 Inch Barrel Parker or the "lower-end" springfield armory 1911........ Model 1911-A1 .45 GI 5 Inch Barrel Stainless Steel Finish Milita I have spoken with the owner of the store I go to, and I can get the RIA for 449.99. So what do you guys think ? 449 for the RIA tactical or 519.99 for the stainless springfield A1-GI ???
