I have to requalify with my duty weapon (M&P40) soon so I went to the local range to practice. First try I shot my usual 40 reload, 180 plated bullet (Renier) & 6 grains of Unique. At 25 yards ity looked like a huge shotgun pattern, some shots off the paper totally. Duty ammo, 180 GoldDots, did somewhat better but that is some real expensive practice ammo. Tried some reloads using 180 HAP bullets and 6 grains Unique. Not much better, some fliers off by feet not inches. Experienced alot of keyholeing.
Anyone else having a problem like this with the M&P40? I really like the pistol but I can't continue to carry it if I can't figues out the problem.
