Glock 33 Magazine

Factory Glock 33 Magazine

This is the factory magazine for the Glock 33, the subcompact pistol chambered in .357 SIG. It holds nine rounds and sits flush with the bottom of the grip, so the pistol stays as short as possible for concealed carry. G33 owners buy it as a spare to carry, or to replace a worn original with a genuine part.

Features

• 9-Round Capacity — The magazine holds nine cartridges, the standard factory capacity for the Glock 33.
• .357 SIG Chambering — The rear of the body is molded with a .357 marking so you can tell it apart from magazines in other calibers.
• Numbered Witness Holes — Witness holes are small viewing ports in the back of the magazine, numbered 4 through 9, so you can check how many rounds are loaded without unloading it.
• Steel-Lined Polymer Body — Glock builds the polymer shell over an internal steel liner, which keeps the body rigid and helps it resist swelling under spring pressure.
• Flush Floorplate — The flat baseplate sits level with the grip, so nothing extends below the frame and prints through clothing.
• Genuine Glock Manufacture — The body carries the molded Glock logo, so this is the same part that ships in the box with a new pistol.
• Black Finish — The magazine is plain black throughout, the same as the factory frame.

Fit And Compatibility

This magazine is built for the Glock 33. Like other Glock subcompact magazines, it will also seat and feed in the larger pistols of the same caliber, the compact Glock 32 and full-size Glock 31. In those guns it holds fewer rounds and leaves part of the grip open below the magazine. A full-size Glock 31 magazine will not work the other way round, because it is too long for the G33 grip.
