What kind of ammunition do you carry? When I'm carrying my Glock 20, I carry Double Tap 165/180gr Gold Dots. When I have the Sig Pro .40, I carry Double Tap 180gr Gold Dots.
I carry 180 grain only. The higher grain bullets have deeper penetration. Currently I'm carrying 180 Magtech jhp. I also have 180 Federal hydrashocks. 180 grain Winchester ranger jhp. Also some 165 grainSpeer gold dots, did not realize they where 165 grain when I bought them, but oh well. The'll still get the job done, even though I prefer 180 grain.
