My carry load in my G17 is a 115gr bullet doing 1400 FPS. The bullet has a low sectional density and ballistic coefficient, so I wonder about how it will do trying to penetrate through several inches of heavy clothing. I am thinking of changing over to a 147gr JHP in the upcoming cold VT winter. Do I underestimate the fast 115gr JHP bullet? Wanna kill these ads? We can help!
