My own take is if the honchos in charge are satisfied with the results then that's their call. I'm really more interested in the rank-and-file opinion and documented street results that can be verified. NYC likes the Speer +P; you say LA likes 147-grain ammo. I don't have any qualms about that.

That's why the experts' opinions I follow mean something. Those opinions are based upon the real observations and testimony of beat cops. Right now the preponderance of the experts I follow say the 124- and 127-grain +P and +P+ JHP self-defense ammos are the best choice in 9mm.
The beat cops have nothing to make a comparison to. If they are issued 124+P Gold Dots, what do they know about 147's? Their prior ammo to the 124GD+P was the 38 with a solid lead bullet. Also, as big as NYPD is, they have very few shootings. I would be interested to see some data from them, since even with few shootings, with lots of cops over a several year period, you could have a serious chunk of data to work with.

Street results just don't offer any usefull info. People get shot in the hip and fall like a house of cards. Others get center punched, run away, and don't even show up at the hospital. I know a guy who shot a BG in the center of the back as he was running away with a 180 Ranger SXT. He told me it didn't even slow the BG down, he ran off and they never found him. What do you do with an anectdote like that? I know he was telling me the truth, so what do you do, not use a 40 cal? I know a cop shot in the gut with 9mm ball, one shot. He dropped right where he was standing, his partner took two under his vest from the same BG and emptied his 9mm into the BG killing him. Both cops were close to death from infection for a couple of weeks. One shot of 9mm ball was a one shot stop, and two shots of the same ammo, in the same general area, failed to stop. What do you make of that?

Here is my $0.02, and that's about all it is worth. Bullets need to penetrate. Expansion is better than non-expansion. In service style guns, you can have both with most any of the modern bullets out there. The 124's expand and penetrate, and so do the 147's. Heavier bullets go slower, but they are designed to expand at lower velocities. They have bigger cavities and often deeper skiving. 124's are designed to penetrate thanks to smaller cavities and more shallow skiving.

I wouldn't use an old style, ultra light, ultra fast bullet though. IMO, they simply don't go deep enough. An old style bullet, like the Sierra Power Jacket used by Corbon, or the standard JHP's from the bigger makers, at a lower speed might actually work well. It's hard to say since they don't get tested in jello. Maybe a fragile bullet, driven slow enough, would acutally work well and be a good round for recoil sensative shooters?

What I don't think will work well, again this is based simply on nothing other than my own uneducated guess, is a modern, sturdy HP like a GS, GD, T, etc driven too slowly. A 124 GD desigend to work at 1150 and only doing 1000, probably is going to act like ball ammo. That's what 124GDHP's do out of my LC9 and that's why I don't carry them. I'd put them in my G17 if I carried it though. The Ranger T's, and other 147's I've shot through my LC9 are doing 950 which is exactly what they are supposed to be doing, so I carry them.
