I was talking to a gun smith today where I work and he said that it might be both the grip and forearm. He said that not holding the gun the same way will change it. I was shooting a wood grip sunday in a 44. I hit with it and the pac grip.So I agree with you guys that the forearm changes more of point of impact than the grip.Thanks for the heads up. I might of missed this fall not knowing why except I just plain miss sometimes.Good hunting
