If you’re into short barrel and Glocks then you may want to get a modifying kit for the Glock. CAA has a conversion kit that converts your Glock into a carbine. (sort of) Its aluminum and polymer RONI unit doesn’t add any barrel length, the pistol is encapsulated, has an adjustable stock with cheekplate, a vertical foregrip and has lots of rail space for optics and a tactical light. Buttstock has the ability to store an extra magazine.
