Question about XD9mm Sub Compact....

I know that the XD9mm Subcompact comes with the grip extender mag. What i was wondering is other than barrel length, when you have the extended mag on the gun, is it the same size as the service model 4" and does the mag extender/grip feel loose or akward at all???

Yes, except for the barrel length it is pretty much the same as the service model. No, the extended mag fits in my Sc just fine and is as solid as a rock. I use it as my choice for CCW carry and it is excellent.

Thanks for the info :)
