If you are law enforcement, you can buy full capacity LEO magazines for $30, I think. If you want to get full capacity pre-ban magazines, call Jack Norris at Practical Shooting Supplies. I have bought factory pre-ban magazines with the extended capacity base plate for $65 from him in the past. I have read that he has over 10,000 magazines. Here is his contact information: [email protected]

I'll have to second Practical Shooting Supplies as a mag source for Paras --
He had P12 mags available for a great price and he shipped real quick. Excellent service and definetly worth calling and ordering from. He's the best source of mags I've found yet in terms of price, not to mention service.
