Thanks Homie. That's interesting. It's OK to use some factory parts made for another model (e.g., it's OK to use the factory G34 extended mag release in a G17), but that ruling doesn't apply to mags?
Confusing. I also read the 2008 rules as making that ruling irrelevant, because of the new "box" rule.
I just want to mess around at local matches without getting blood blisters in the palm of my hand. If I wanted to game it, I wouldn't shoot a G19 in Prod.
