I have some, I like the way it looks, but the stuff is pretty darn expensive. I got some LEO boxes of HST's and I like them a lot too. The PDX1 I have is +p, which really isn't a plus in my mind. A 4" barrel really doesn't need the extra push, and it is noticablely more recoil, though not a lot more. I'm more worried about getting more rounds on target, faster, than the extra 50 or 80 fps I get with a 124 grain bullet. I prefer the 147 grains, but they are harder to find.
Just my opinion. I don't think they are any better than HST's or gold dots or vice versa and you can find those in LEO boxes online.
ive seen it test VERY well, and ive seen it test VERY bad... my own personal tests into ballastic gelatin was fantastic!... into water jugs though sucked and it fragmented all over and separated from the jackets.
