Picked up my MR920 and put a DPP on it. Took it to the range and ran it on timed draw and rapid fire drills and they are very, very similar in performance. Maybe just a whiff of an edge to the MR920 but within noise of my testing. For illustration: 10 rounds each. 2” paster. Yes, I know. Not my best shooting and had a flier on both. Frankly a little disappointed in the MR920 and again impressed on what a competent gun the Glock is.
