I’ll be picking up my new Gen 4 Glock 17 soon and began to research the best round for self defense. The more research I did the more confusion that resulted. I’m an old revolver guy so this is pretty new to me.
If expansion is your goal, the Winchester T-series is an amazing performer.
Otherwise and IF you can find it, NATO spec FMJ 124 at 1,250 fps creates a rather impressive temporary expansion cavity going ALL the way through a gelatin block.
Like most, I used to be a big on HP design, but in recent years I've come to favor a TC-FMJ design driven as fast as possible for EDC carry.
