I have a M10-7 with 4" barrel. To what bullet weight and muzzle velocity does S&W regulate this revolver?
Can I assume that M10s are regulated to 158 gr. LRN?

Dick, it's Dawei; all fixed sight 38 Special revolvers are regulated to shoot POA w/standard pressure 158gr ammunition.

Hello, good to see you here. About what MV would that translate into? 750 fps?

755fps, although any 158gr load 750(std press)-950fps(+P) will shoot to POA in my experience.

Handgun sights aren't sighted in to bullet velocity but to a specific bullet weight. Like said above, a fixed sight S&W .38 Special is sighted in using a 158gr bullet.

Thanks. That is helpful. I am in the process of standardizing a general purpose load for use in M10, M15, and M36.
158 gr. lead bullet at 800-ish fps MV will be my starting place.
