I bought this spacer to make up a USPSA drop/offset holster rig without paying the high dollars asked for some other kydes DOH rigs out there. One hangup I had was that the screws provided did not fit with the standard CQC holsters I was using. Not a dealbreaker, but I did have to drive to the hardware store to seek out correct machine screws for it. I think it would have been fairly easy for Blackhawk! to either state that the screws won't work at all, or include 3 little screws.
Pros: Moves holster farther outboard
Cons: Needed different screws to work with CQC holsters
