Sir, RIAs have a level of quality all out of proportion to their price. Granted, I modified mine to a large degree but, not because it needed it, because I wanted them and I can't keep my hands off of things. As a justification, some of the Mods are because I'm Left-Handed. In close to 14,500 rounds my Rock has been dead reliable for over 14,000 of them. I actually chose it over a brand-new SA Milspec loaded, for only $100.00 more( The SA) because the Rock was tighter, smoother and had a better slide to frame fit. I had the money to buy either gun.
As for the rumors of out of spec parts, frames, etc, that hasn't been my experience with RIAs. This is evidenced by the aftermarket parts I've fitted to it.
It's also every bit as accurate as higher-priced 1911s, mine, from the beginning, would shoot under 2-1/2" at 25 yards from a rest. Most Base-Model 1911s from the other manufacturers will not do this.
All in all, I think RIAs represent the best value out there.
