im gonna order acouple of boxes an try it. how many rounds do you shoot before you trust it?I use it in my carry gun, a .45 XD Compact. Just shot some more of it today actually. I have never had any problems with it, and feel comfortable carrying it. A few people on here have had problems with their XD's shooting HST though. Feeding issues I think. Try searching this room and the Ammo Can. You should be able to find the threads discussing it.
Even though a few have had malfunctions with it, if you are interested in it, shoot a couple of boxes through your gun and see how it goes. If you have an XD, chances are it will love it. I don't trust my life to any ammo I haven't shot the hell out of first.
