The grip angle is entirely different than the GLOCK. In fact, the HS/XD is actually closer in design to a SiG than a GLOCK.
The trigger is, IMHO, far superior to the GLOCK in feel, weight and break, but the reset is much longer. If you're used to the GLOCK trigger, the XD will require some retraining.
I bought one of the very first HS2000s when they first hit the shelves. I chose it over a GLOCK primarily because of the grip angle. Since I shoot mostly HP, SiG, STAR and 1911 semis, the grip angle of the HS felt far more natural than the GLOCK.
Give one a try. It's a world class pistol that is still grossly underpriced.
