I have two Ronins in the Commander length, (9 and .45), they DO HAVE aluminum frames (and ramped barrels). Both shoot nice, but both shoot about 3" high at 50 ft. No matter, until I can get new front sights, I can adjust my aim point. They seem to shoot remarkably soft for alloy framed receivers.

You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
