I have one of the Rock Island Armoury 1911 tactical models, I have only put about 400 rounds through it, haven't had one jam with wad cutters or hollow points. It is good for what it is, a cheap pistol. Appears to be reliable. I read they were not made for wad cutters or hollow points, backside of barrel was supposedly cut flat and they would not feed properly. I took it apart to fix the issue and mine already had metal removed, I bought it used so I don't know if the previous owner worked on it, or if it came from the factory this way.
