Yes, I think the ergos and trigger are most of it. I was shooting with a buddy that has an XDM, 9mm. Off the bags, I was hitting an 8" steel target at 50 yards consistently with my 75B, but neither of us could hit it even once with his XD.
I'm just not a fan of the striker fired guns but both of my CZ's just feel like they were made for my hands.
