Pistols that can accept a red dot and be carried?

Looking for something around G19 size (can be a bit smaller or larger) that can accommodate a Trijion RMR on the slide with irons. I don't care if it is gtg from the factory, or the RMR can be attached with aftermarket slides or milling, what matters is that the red dot also allows for the use of irons after install. In other words, I don't want it to attach using the rear dovetail style mounts. The idea is to put it in the training and carry rotation. "Why not just get a G19" I hear you say. Well I might, I just want to know what my options are.I'm open to all suggestions, and if anyone has a list of pistols that can accept red dots from the factory and aren't 6in slide monsters that would be very helpful.Edit: since there seems to be some confusion, let me be clear: I know you can mount an rmr on a g19 about 10 different ways, and I may do that. I am asking for possible alternatives, factory or otherwise. via /r/CCW http://ift.tt/2mrVHQy
