I've shot a few thousand. It is good ammo and fairly consistent. The primers are slightly hard. Meaning with striker fire guns, you might get an occassional light strike. That will happen 1% or less of the time with my striker guns (M&P and P80, most with trigger mods).
With a hammer fired gun, I have had no light strike issues.
I was buying this stuff like crazy when it was $0.05 (or more) less than other target ammo. Now that other brands have come down a bit more, I have been buying other stuff.
Long and short of it is that it is decent for training and plinking. I stopped using it for competition with striker guns because of the occassional LS issues. I would not recommend it for defense (then again i would not recommend any 9mm ball for defense).
I would still buy it if the price was right, but I'd pick a different brand if it was only a couple cents difference.
