The XTP in 9mm is my hollowpoint of choice.
The saying is that we like expansion, but we need penetration. You get both with the XTP, in my experience.
I tested them against my former hollowpoint, a Nosler 127-gr JHP, shooting against very aggressive cans of beets. The Nosler hit the can dead center, made it jump a bit, and split the can in the back.
While I was reloading with the XTPs, my buddy shot another rabid beet can with his 12ga shotty, and as would be expected, beets went everywhere.
So I lined up the sights at another can with an attitude, and the resulting explosion of beets had me thinking it had been shot with the shotgun.
I checked the remains of the can, which had been emptied of beets. The curved portion was flattened.
Needless to say, I was pretty impressed. I don't know how well they would do as a personal defense round, but I keep a magazine loaded with them anyway.
I like 'em.
