This is not a big supprise. The State Police had huge failuer rate with their Glocks. When they tested XD's againsed Glocks the XD won every time. Saddly Glock cut deal with the _(&W#(@)HDI)&& bureaucrats so the troops are still carrying Glocks.
Talking about the problem when having a light attached?
Was some of the .40's, but it's been addressed.
I'm sure XD's are nice and all but some of us don't like that TALL slide, but XD's have had problems of their own.
