Para Ordnance still makes high cap magazines (or has them made). They are a Canadian company that sells pistols to police agencies in the US, and civilians worldwide (in markets that have not banned high caps). They included a coupon with pistols manufactured prior to the AW ban that can be redeemed now for two high cap mags.. at about $40 a pop. Delivery of those mags takes 8 to 12 weeks, therefore, I suspect that they are being ordered and manufactured to order - not being sourced from a warehouse.
