Want to Buy WTB Glock 9mm Double Stack Mags

I'm looking to buy some mags compatible with a G19 Gen 3. I'm looking for any capacity stick mags so long as they're 15rds or more, a drum, or a 100rd double drum. I would also be interested in an MBX metal mag at the right price or metal/extended baseplates. The brand and condition doesn't matter that much for the mags so long as they work, but I'm really not looking for new mags unless the price is right. If you have anything, shoot me an offer. I would also potentially be interested in a SafariLand G19 holster. Ships to VA
