I noticed that my P3AT shoots low. I have to place a 12 o'clock hold on the target to get it to shoot at the bulseye. I personaly like to have a 6 o'clock hold on a target so I can see the shots comming. The first shot I fired I placed the fron blad center of the target and the shots was at the bottom. I thought about taking a file to the front site, to change the POA. I was wondering if anyone else has done this. Does anyone know what ammo/bullet weight these guns are sighted in for?
