 The Bull Armory Axe FS Hatchet. Everything that you may add to a Glock is already on here. Check out that grip stippling. And it has an integrated flared mag. Well, 17 round mags, they are Glock interchangeable, but this is a Bull Armory mag. Look at those slide serrations. All throughout the top straps, a three and a half pound all metal trigger with a short reset. A direct mount with an RMR footprint and have a Hollison 407C on here. Together, the combination is great. It does have the extension right there with the slide stop, takedown levers, the aluminum trigger. I love this handgun, $620. Where can you find a Glock handgun compatible to the size of the Glock 17 with all these additional features?
