I went back and forth with a guy that does testing for the FBI and a bunch of other LEO services. Specifically he tests how deadly specific rounds are, how they perform in various conditions, penetrate armor, etc...He recommended Winchester Ranger 127gr +p+ for 9mm. So that is what I use. For what it's worth.
Winchester Ranger is used by a number of law enforcement agencies. I have a number of boxes of Ranger 9mm, and it is marked Law Enforcement Ammunition right on the box.
I use that in one of my handguns, but it doesn't load well in the other 9mm I have. The bullets are a bit longer and different shaped than most and every once in a while it would hang up on the lip of the hollow point when feeding. It's actually the only bullet that gun has ever had a problem with and I've probably put at least 20-30 different bullet types through it - factory and reloads shooting IDPA several years ago.
That is interesting. +p+ will also throw certain guns off, and many are not rated to run it. A lot of pressure, slide racks super fast. I've put a 150, or so, of them through my 19 w out issue. But good call out in general. Not everything acts the same. Get time in with what you are planning on carrying.
