Extended mag release.
I just installed a Lone Wolf extended mag release and handle plug on my Glock 22. It works great. The mags lock in easier than before, and you can drop them without shifting your grip. I shoot left handed and it's really easy to drop empty mags with the middle finger of my left hand. I reccomend this upgrade to any and all glock owners. I'm also running Trijicon night sites, and give them two big thums up too. Low light acquisiton is a breeze.
Was that incoming, or outgoing?
