Well I have 30 firearms that use that mag and even though I have a few of the Butler Creek steel lips I only depend on the factory mags. I have well over 100 factory mags and if I want higher capacity i use a product called Trimag that joins 3 of the factory mags together in a triangle shape. You use 10 rounds pull it out and rotate and so on.
I have a couple of the 50 round drums from Blackdog and can not get them to function more than a few rounds before they jam up.
I even have some of the clear mags that have been colored to match certain builds.
Bradis keeps the Tri-mag in stock at 9.95 each
