The recoil was only bad with the M4 style stock with it's thin edged butt plate.I agree with MistWolf except for the recoil. I really never noticed it
Switch to MagPul mags and try commercial pressure ammo (not milsurp) or reloads loaded to commercial pressure until the rifle is broken in and the gas system has a chance to seal itself. You didn't say what kind of malfunction you're having, but I'll bet it's short stroking. The M&P-10 is tuned to run on commercial pressure ammoI bought a new m&p 10 ln November the camo hunting model. Piece of junk. Its been back to factory 2 times . It jams constantly. S&W says it doesn't jam for them. They won't replace it. No more S&W guns for me.
