My brother has a Rock Island. He bought it mil-spec, and added some parts like the full length guide rod, beavertail and things to it. He just was talking about it the other day, he has about 10k rounds through it and it has held up very well for him. It was always reliable. He realizes its no Kimber, Smith, Springfield, Etc, but for the $350 he paid new for it a few years back hes very pleased with it.
