:roll: Jump2000, Hello! The GLOCK FML magazines are more durable and seem to function better. The sides on the GLOCK NDF magazines bulge when they are loaded; this prevents the magazine from dropping free. (An inconvenience, at best, and a genuine hazzard in a gunfight!)
If I had to use another manufacturer's magazine in my GLOCK, it would be a Scherer; these seem to be the most reliably built of the aftermarket crowd. :grin: Regards, 'Arc Angel'
