My 40 will do a 200 at 1025. Empties land six feet away. Increasing Longshot powder carefully, it is running 1115 with same bullet. Empties land six away. Primer pockets remain snug. I tried a geelock number 20 some years ago. Not easy to attain 1200 fps AND KEEP PRIMER POCKETS SNUG. I did not try AA9 though. My neighbor has one so I’ll try in his. And I could not stand that idiotic grip angle or the grip size. I wear xxl gloves by the way. I shot the block with the same bullet as I’m shooting now. Shot a couple thousand rounds from it with good reliability. I’m over a thousand rounds from an M & P 5” with complete reliability, a grip angle that is compatible with fifty years of 1911 shooting and a thumb safety.
