Here in California, a 10 round magazine is the maximum you can have. I have been looking at a few pistols the come with 15 round mags. How is this handled? I would assume the FFL would open the box, remove the 15s and put in two 10 rounders. Do they replace them with 3 10 rounders as this wouldn't fit in the packaging? What does the FFL do with these large cap mags? Is this handled by the distributor since they know it is heading to California?
