ProMag GLK-17 7-Round .45 ACP Magazine for Glock 36 Black Polymer

The ProMag GLK-17 magazine delivers reliable feeding and extended capacity for Glock 36 pistols chambered in .45 ACP. This aftermarket magazine provides shooters with a cost-effective solution for training, competition, and backup magazine needs.

What Makes This Different

Unlike factory magazines that typically hold 6 rounds, this ProMag design increases capacity to 7 rounds of .45 ACP ammunition. The polymer construction reduces weight compared to steel alternatives while maintaining structural integrity under repeated use. Heat-treated chrome silicon spring ensures consistent feeding pressure across thousands of loading cycles.

Key Features

• 7-round capacity increases firepower over standard 6-round factory magazines
• Black polymer body construction resists corrosion and impact damage
• Chrome silicon spring rated for extended service life
• Drop-free design allows rapid magazine changes during reloads
• Witness holes provide visual ammunition count verification
• Anti-tilt follower prevents feeding malfunctions and double-feeds

Field testing demonstrates reliable cycling with various .45 ACP ammunition weights from 185 to 230 grains. The magazine functions consistently in competitive shooting environments where rapid reloads are essential. Law enforcement agencies have adopted similar ProMag designs for duty use due to their proven reliability record. The polymer construction withstands temperature extremes from -20°F to 180°F without affecting spring tension or feeding characteristics.
