I have an XD 9 sc black slide with od green lower.
With good ammo the 9 shoots just as accurate as the full size 45. It is my EDC, has 147gr rounds, the extended mag holds one more round then advertised after a few cycles.
I have big hands and with the short mag I can't shoot it well, a houge slip on grip took care of that.
At some point will get night sights and may do a trigger job and barrel upgrade... Out of the box it is a great gun.
