I have shot this Ammo. in a Sig P227 .45 a Sig WK-25 navy 9mm a Walther PPQ 9mm and a HK VP9 9mm. No FTF or FTE in any of my handguns,also it gets for me good groups. All my range requires is I keep it away from any brass this is easy using a separate container. HK has something about not using it but I called and they said it might cause ejection problems,but if just shooting at the range that was not a life threating problem as if using it in defending your life.
I would just never use this Ammo. as carry Ammo.
