Beta Company has a 100 round 9mm C-Mag on the way for the Glock. While I’m sure there’s a market for an accessory like this, to me it doesn’t seem very practical. Even in a zombie apocalypse. Weighting in at a hefty two pounds unloaded, it’s sure to give you a workout. It’s currently available for pre-order at Betaco.com and starts at $380 with the clear backed model shown above starting at $390. They should ship in 12 to 16 weeks. Just hope the living dead don’t start rioting until then.
