$60-100 per mag?! Is this because they are early gen mags? Because if we're simply talking mag capacity.."standard" capacity mags that are legal in most other states run around $30+/- for a 17rd mag. Can't see anyone paying double..again unless they're somehow marked early-gen mags and considered collector's items. Besides..if he bought his gun way back when..those mags should be grandfathered in and he's legal to have them. Same thing if you bought "standard" capacity mags a few years ago during "Freedom Week." He should have a 17rd loaded for HD vs a neutered 10rd mag.
