It is smaller from what I recall. I have medium/large - wear size 9-10 gloves - and mine came with the small grip frame. I had to get the medium size frame to make it feel better for me. At around $50 and a long search, then wait for the grip to arrive, I decided to trade it off. I had no problems whatsoever with the gun though. Soft shooter.What was the grip's size comparable to? Was it big as a Glock 21/30? I have an M&P 45 M2.0 Compact that is roughly the same size as a Glock 45/19X, but the grip, with the small backstrap installed, is just a touch bigger than an M&P 9 with the medium backstrap.
