I have a Sig Sauer P220. For some reason (could be my error), the laser is 3-4 ft. below where I normally aim (and hit) at 25 yds.
I've tried with the U and P cross members. I've adjusted the elevation every which way. I'm sure the unit is mounted on my gun correctly. I'm in touch with Optics Planet to try to figure out what happening. It's possible I'll replace it with an X300 if they'll let me.
Pros: Well built
Cons: Possible problem with sighting in laser
