My personal 9mm favorites are the Speer 124gr GoldDots, the Winchester Ranger 127 +P+ SXTs, and the Corbon 115gr DPX ammo. Gold Dots in various calibers seem to be widely used by police departments, with good results. I think Winchester Ranger is not as widely used, but also has a good rep as far as I can tell, especially the 9mm version. Corbon DPX doesn't seem to have as many actual street shootings behind it yet, but some people I respect and think knowledgeble rate it very highly.
I currently use the Winchester Ranger ammo because a) I was able to get a lot of it, and b) Corbon DPX is just so flaming expensive. I like to shoot a lot of rounds through my pistol and all of its magazines to verify reliability, and with DPX running over $1 per round, that gets expensive.
If you are interested in the Win Ranger line, I purchased a case or two of the Win Ranger 127 +P+ from Jerry Kirkpatrick ([email protected]
) in Florida. I had seen him advertise on various forums like the 1911-related ones, and he always seems to have Winchester Ranger in various calibers for reasonable price (also Glock magazines). A number of people commented favorably on him, so I took the chance, and was pleased. Have done business twice with him and found him prompt and reliable.
If you did thru this post of mine,
you will see some limited wetpack testing of the Win Ranger 9mm 127 +P+, if that sort of thing interests you. And of course check out Stephen Camps link above (and check his whole website, not just the ammo link).
Good luck and best wishes.
