Understood Newlife503. Hopefully some M&P Shield shooters will chime in. Also the M&P would be considered a combat pistol, so it depends where you put the front sight.
"Guns which are sighted in for a combat hold require the shooter to place the front sight where it covers the exact center of the target, while guns sighted in for a target hold achieve greatest accuracy when the front sight is aligned at the center of the bottom of the bullseye."
