If you live in a state that has a 10rd magazine capacity restriciton, and you had to use the "high cap magazine removal service" buds doesnt replace the magazines in those circumstances, if you purchased a seperate magazine it may be in a seperate shipment that's coming directly from a distributor, if neither of these apply you'll need to Call buds during buissnes hours at 859-368-0371, 9am-9pm eastern Mon-Fri
use the Blue Chat now button at the bottom right corner 9am to 9pm Mon - Sat and 9am to 7pm Sunday

I would use Chat now to get in touch with a Buds representative. Quicker than a phone call and being on hold. You can always call later if chat does not resolve it.
