The Glock 33 round magazine is a composite steel and polymer fabrication. Sometimes referred to as a Glock “Happy Stick.” The extended magazine is only available in 9mm. The mag encases a toughened and hardened steel insert in Polymer 2. Gaston Glock himself invented Glock polymer 2. Polymer 2 is a high strength nylon-based polymer. As a result, this polymer makes the Glock Magazine incredibly durable.
33 round mags are back in stock.
Glock Extended Magazine
Extended magazines for 9mm Parabellum have been around since the mid-eighties. What makes the Glock “Happy Stick” so ultra reliable is its pedigree. When Glock developed the selective fire Glock 18 for EKO Cobra in 1982, a high capacity magazine was part of the brief. Cobra, the Austrian counter-terrorist group, required a magazine that would feed without jamming. Period. As a result of the G18 ’s rate of fire of around 20 rounds per second, this is an exceptional engineering achievement.
Polymer 2 is more resilient than steel. Consequently, this composite magazine assembly can withstand a lot of abuse and still continue functioning. Especially relevant is that this magazine will withstand visible damage or deformation after being dropped on solid floors from considerable height.
There are only 31 witness holes on the rear of this magazine. The Glock Happy Stick has a plus 2 shoe fitted and is marked 4422-02. Older Glock 33 round magazine variants originally made for the G18 have no part number. Older mags are just marked – Glock Austria. Again, they have only 31 witness holes.
Reliable ammunition Feeding:
Only selected and expertly heat treated steels make up the magazine spring. As a result of the accurately manufactured spring and follower, the Glock Magazine feeds ammunition with total reliability. The magazine body has twin cuts. Due to this, the Glock Magazine 33 rounds is compatible with all Glock Gen 4 semi-auto pistols with the magazine catch in left or right-handed configuration.
