I have both the XD9 service model and the XD9 SC. Is there any problems with using the mags for the full size grip ( without the extra plastic extension piece) in the SC?
Only feel that I know of,,,i used my mags without for some time and never had any issues.
I do it all the time at the range, just looks odd.

We, the People are the rightful masters of both Congress and the courts not to overthrow the Constitution, but to overthrow men who pervert the Constitution.
No problems at all using the larger mags. Like what someone else said, feels strange but who cares. The system works. I do that all the times with my glocks. I carry with the smaller mag in the gun but carry the larger mag for reload.
