I've been on the fence about picking up a RO for a while now. I decided that I want to step it up to a TRP. Kind of a happy medium between the RO and the Professional. I can't narrow it down to which TRP model to get. I am thinking the Operator, but is there anything to think about? Does a rail with a light attached have ANY negatives like those seen with .40 Glocks and a light? I am sorry for asking this here, but I am hoping someone like Quack or bac can post some info and pictures to help me out. This will be a one stop gun for me, so I can't just buy one of each and decide which works out later like some of you big $$$ guys. Budget is 2k for the gun and any tweaking or modifying it needs to be 100% solid and accurate. I dunno if the TRP comes dialed in, or if it needs to be tweaked. I handled a RO and decided I'd just prefer a TRP. Maybe I will get a RO down the line, but I just want to step my game up this time.
