How much difference do thicker grips make? I can put rounds through the same whole with my 92. I took my 1911 out the other day it has thin grips on it and it seemed as if I was shooting about 2 inches high. I am wondering if I am gripping it wrong? I did not have my thumb riding the saftey. I know I prefer thicker grips. So I am wondering if thicker grips would help?
