I prefer the 147-grainers; like the Federal Hydra-Shok, Federal Premium Hi Shok or the Federal Classic load - or the Winchester SXT. They are all standard pressure loads, which I like; less wear and tear on the gun.
Winchester's "Law Enforcement" 127-grain +P+ is another one, but might be hard to find.
I used to carry lighter bullet +P and +P+ loads, but after studying all the material I could find on the subject I switched to the heavier stuff. The lighter quick expanding bullets just don't penetrate enough for me. I am more concerned about not enough penetration, as opposed to too much.
Don't forget of course to make sure that whatever you settle on cycles reliably in your gun.
I think you're on the right track with the COR-BONs 115JHP. That's what I trust in my wife's 3913 that she carries everyday! I like them because they work all the time, there is virtually NO muzzle flash and they're widely available. Their track record is also pretty impressive!
In 9mm, as all pistol calibers, shot placement is critical. I carry Winchester 115 grain Silvertips in my Hi-Power, Federal 115 grainers (Fed 9BP), or Corbon 115's. Since my Hi-Power likes the Winchester stuff I stick with it, mostly. The Winchester and Federal standard pressure stuff is giving about 82% one shot stops and the +P slightly better.
I recently asked this on a couple of other lists. This is the response I got.
First and foremost, 9mm is a marginal at best round to use for self-defense.
But, if a person wants, or has to carry it:
Winchester 124gr +P+ Ranger RA9SXTP
Federal 115GR.(+P+) Hi Shok 9BPLE
In 9mm my preferences is for 124 grains. I practice with M882 and my carry load is Gold Dot 124 grain. The design of any of the newer generation 9mm is great. I doubt you could go wrong with Golden Saber, Gold Dot, Ranger or Hydra-Shok. As has been mentioned previously, its all about placement. Put the round where it belongs and the caliber is not going to be a problem with 9mm. Good luck.
Speer or Black Hills' loading of the 124-grain Gold Dot. Federal Tactical if you can get it. Winchester's 127-grain +P+ is a good load, but it really won't do anything the Gold Dot won't do at lower pressures. Cor-Bon has spotty quality control, and the 115-grain load from them tends to fragment and underpenetrate. I've seen it do as little as 7 inches in gel. I have yet to see any information from a reliable source that indicates it has a good 'track record' in real life.
The Speer 124+p GDHP is used by the NYPD and the have documentation on actual shootings, documentation show the Speer to be a great stopper and great on barriers. My opinion based on actual shooting, and NYPD has a few, is any 124+p bonded bullet from the top ammo makers should do it. My choice only two 1. 127+p winchester, 2. 124+p Speer GD, speer has a little more flash but liveable. I would carry either. Oh and one other consideration, the 124+p GD loaded instead of 1220 fps but to a sizzling 1310 fps made by Double Tap. Harsh wear, expensive, reliable, harsh recoil, accurate, and 357 Sig power, I sprung my Beretta to shoot this load and has 16 in it as we speak. Recoil still not on par with a 45 and the only mind set you need is you may have to throw away you gun after a few years of a steady diet. When I can, still perfer 200gr+P GD in a 45. Oh yeah DT make some of those too, but I ain't throwing away my 45.
