I have a plain jane parked RIA in 38 super, and have never had a problem of any kind, it is a little ammo picky as far as accuracy, but will eat anything. I also have a kimber target in 45, and it has gone back to the factory twice for cosmetic defects and jamming ( tight extractor/loose ejector), my colt, only once for what was an overly tight extractor causing jams. The colt is the prettiest, the Kimber is the most accurate, but the RIA makes the most trips to the range, and is definitely the best buy of the three.
The RIA have the "bull barrell" that is of uniform thichness, and not reduced in the middle like older colts, doesn't have the trigger or drop safety, and has no MIM parts. It is about the closest thing available that is true to the original 1911A1 design, and that is readily available new, and accepts just about all mil-spec parts. The only downside are the standard sights, and lack of an actual stainless model, but for the price, who cares, You can buy a RIA, have new sights staked and pressed in, put in a couple high speed low drag parts, buy some extra mags, and ammo, all for the base price of a high volume MFG's copy and their "improvements" on the original design.
