Does anyone know the bullet weight and distance the 2" is regulated for? Kimber CS said the techs test for sight regulation at 25 yds! I just shot it for the first time and with SGD .38+P and .357 both 135 gr short barrel it shot about 2.25" low at 7 yds. I was hitting a paper plate well at 15 yds with 158 gr .38 standard pressure. Seems a bit crazy to regulate the sights of a SD snubbie for 25 yds. Obviously I will test different weight bullets at various ranges and figure this out but was curious if anyone "knew" what Kimber intended.
