Glock 31 Magazine - 10 Round

Features

1. Factory OEM Glock Magazine — Genuine Glock-manufactured magazine built to the same tolerances and quality standards as the mags shipped with your pistol.
2. 10-Round .357 SIG Capacity — Holds 10 rounds of .357 SIG, making it compliant with capacity-restricted states while still fitting full-size Glock 31 frames.
3. Steel-Lined Polymer Body — Full-length steel insert encased in high-strength polymer resists deformation from drops, impacts, and harsh environmental conditions.
4. Cross-Compatible Platform Fit — Drops into the Glock 31 full-size and also functions in the G32 compact and G33 subcompact .357 SIG pistols.
5. Numbered Witness Holes — Rear witness ports let you quickly verify round count at a glance without disassembling the magazine.
6. Branded Polymer Baseplate — Slim factory baseplate sits flush with the magwell and is removable for cleaning or follower replacement.
7. Caliber-Specific Follower — Dedicated .357 SIG follower geometry ensures reliable feeding of bottlenecked SIG cartridges, distinct from the .40 S&W version.
8. Corrosion-Resistant Finish — Black polymer exterior and treated internals stand up to sweat, holster wear, and field use.
9. Made in Austria — Produced in Glock's Austrian factory to original specification.
