How does this (IER) scope work out on an xp-100? TIA.

I've got a couple of them. They work out great on the XP. They do take some getting used to though. Very sensitive as to eye placement and a small field of view. But I like them better than the 3-9 Burris pistol scope.
If someone would make a straight 12 or 15 power IER I'd buy it. 'Till then, I'll stick with the 10X Burris for my long range pistols.
