The Springfield XD seems to be very similar to the Glock but there are
some major differences. When you pull the trigger on a Glock, you are
in fact, cocking the striker about halfway. When you pull the trigger
on the XD, you aren't cocking the striker at all. Because of that, the
ATF considers this pistol to be a single action pistol. When the XD
first came out, Springfield called it a single action striker fired
pistol.
Because this pistol is considered a single action, it cannot be used for
Stock Service Pistol Division. It can only be used in Enhanced Service
Pistol Division. Glocks are classed with double action pistols because
of the fact that the trigger pull finishes cocking the striker.
