I have a model 360J in 38 Special +P. I am disappointed that the POI is almost 3 inches to the left of POA. I've done plenty of shooting to know it's not me. The groups at 15 yards all are about 3.5 inches in diameter. Shooting was done 90% off-hand and 10% rested on bench. I used standard velocity 130 grain FMJ and 158 grain FMJ ammo. Only the elevation changed. All machining seems to be very well centered regarding the sights. I have 3 J-frames that all shoot well horizontally. Any recommendations out there?
