the HAP bullets are just a competition version of the XTP. hap are non-expanding and would feed no differently if that help any? 1 of my next pistol buys will be a 92 of some variant (starting with the gts).
Suggest buying a Few (100?) of several different slugs. Load ‘em and try ‘em in YOUR pistol. Go with what works best. I’ve had great luck with Berry’s plateds in multiple nines. Recently found a “deal” on some 125 grain “coated” (synthetic) slugs. Bought 1000. They load fine but run like crap in all three I’ve tried them in to date. Lesson learned, Try before you stock up.
