I have a new M&P Pro in 40S&W and got the storm lake 9mm conversion. The accuracy of the storm lake barrel is great but my point of impact is 6 inches lower than the factory 40 barrel at 7 yards. Has anyone else had this issue? I know I can by adjustable sights but it seems odd.

Mine shot the same POA as the 40. Call Storm-Lake I had to call them with a problem with a compensator I was trying to use on it. They was great to talk with. Don

I just got a 40c and bought a 9mm conversion barrel for it but haven't had a chance to try it out yet. Have shot it in 40 and it shot POA.
You didn't say type of ammo you wer using. Did you try different kinds of ammo possible different grain bullets ?
Was the group you shot consistently in the same area, but just 6 inches low?
Did you get the 9mm barrel or the 9MMc barrel ? 9MMc is how mine is stamped from Storm Lake.
