Never used a Wilson Combat but I'd say the Wilson's are a cut above. Mine work with anything you put in them and they're much better feeling than the ACT. They look and feel more like a Colt mag. They can't be disassembled is the only drawback I can see. I would imagine the Wilson's have a better finish also but for the price they're top notch in function and reliability.
The floor plate is drilled if you wish to put bumpers on them. Personally I can't stand bumpers.
