I am going to be getting Winchester Bonded PDX1 147gr 9mm for my Glock 17. This is the standard round for the FBI. People have also done tests on the expansion of the rounds, and they were getting extremely consistent expansion. As soon as I get my Glock, I will be buying some of these.
How is that bullet any different than a 38Special?
I thought the FBI uses .40S&W.
I use Ranger +P+ 115gr bullets at 1350 fps. Recommended for strong guns only like Glock, Beretta etc.
