Just broke through a 1000 today and took her apart for the first cleaning since the original take down. This gun continues to impress. I am routinely capable of creating 1 hole groups at 10/15 yds. Experienced 1 ammo related malfunction, most likely due to not enough powder in my reloads.
About 800 rounds have been with the small backstrap and I decided to give the medium a shot to see which one may be better. I also stippled the medium backstrap and the improvement is substantial. I experienced some slight shifting of the pistol in my hand when shooting for prolonged periods, but now with the stippling, it sits still.
I also observed that if you have an M&P FS, the P09 magazines will fit and feed rounds. Although you will lose the last round hold open feature due to follower geometry.
Also tried out my new bladetech holster. The retention on this thing is no joke. Fits the pistol perfectly fine and the tech-lok attachment is secure.
All in all a fine pistol, which is completely underrated for it's price. More people need to be made aware of their value, so we can get some more aftermarket support.
