Went to the new Cabelas here in Denver yesterday with my 12 year old son and step-dad. My son and I were looking at 22 pistols. He really liked the S&W M&P until he held the Sig 1911-22. Then we saw the ATI slightly used for $100 less than the Sig. Comparing the 2, it looks like GSG makes both. They are exactly the same other than the name on the side. Grandpa stepped in and bought it for my son. There was one happy kid at Cabelas last night! Does anyone have any experience with the ATI?
