I am disappointed with my RIA. I recently bought a 22 TCM Micro Mag 9mm. The grips screws are not normal size and the grips are not replaceable. I bought a set of VZ Grips that are made for the Para P14. I was told they would fit but they don't even come close. I have tried for a week to get a hold of Armscor. But no luck.
I advise you to save a tad bit more money and get a Springfield, Colt, Ruger, Taurus, STI, Kimber, Smith & Wesson, etc.
Rock Island Armory is not a bad gun. But I've just not had the experience I was hoping for with mine. As the saying goes. You get what you pay for.
If guns kill people, mine are defective.
