"Happy stick" is a slang term that can be used in reference to large-capacity Glockpistolmagazines containing 33 rounds of 9mm intended for use in the Glock 18 fully-automatic machine pistol. These 33-round Glock 9mm magazines fit and function in other 9mm Glock handguns and are extremely popular with shooters. A .40 S&W caliber version of the "happy stick" exists that is reported to have a capacity of 22 rounds.
