Also checkout JoeBob's New +4 GSG 1911 High Capacity Followers
and Loader Assist Button.
Loader assist buttons work perfectly with the upgraded followers! They can also be used with factory magazines if you drill a 1/8" hole in the factory follower. Save your thumbs from the hard to use "nubs" the factory magazines are notorious for!
These magazines will also work with Sig Sauer 1911 22LR pistols
