My duty weapon, Smith & Wesson M&P40, shoots severely low. During qualifications, shooting 180 grain Speer GoldDots at 25 yards, this pistol shoots approx. 12 inches low. I haven't been able to duplicate this error using my reloads of 180 grain FMJ bullets. Does S&W sell taller rear sights that I can use to correct this? The GoldDots are our required carry loads.

They claim to sell different height sights to correct elevation issues, but good luck finding a chart to see the height of the standard one, the options offered and the approximate correction at 25 yards attributable to each of the optional sights.

Is it the gun or the shooter? Using a mount or rest, with slow, surprise trigger pulls, is the only way to determine exactly where the gun is sighted, per your sight image. Low impact points and low left impact points are normally associated with a pull/flinch, and not always sight related.

Most M&P full size and compacts, in 9mm, tend to shoot a few inches high at 25 yards. The standard front sight is .160 tall, off the top of the slide. I had to put a .180 on mine to bring it back down to POA.

Twelve inches at 25 yards is quite large, in fact it is bordering on huge. I think that it's highly unlikely that you'll find a sight set to correct for a deviation this large. As Rob has suggested the true cause for this issue is likely the shooter. To confirm or negate this possibility I would suggest that you have someone who is a proven superior shooter test your pistol. If it's not a problem with the pistol that expert will be able to center the target. If it is a problem with the gun it will shoot low for him as well. In the case of a problem with the firearm IMO it needs to be returned to S&W.
BTW, I would suggest that you refrain from claiming yourself as a qualified expert. Because we have seen a lot of "experts" on the net with flinching issues they weren't willing to own up to. In addition a lot of us old farts have been shooting handguns long enough that we have all had the experience of having to correct for a tendency to flinch. The simple truth is that flinching is a perfectly natural reaction to firing a loud and powerful firearm and anyone who shoots long enough will have to learn how to correct a flinch or take up Bowling.
