Glock G27 Gen 5 Magazine 40 S&W 9-Round

Glock G27 Gen 5 Magazine

This is the factory magazine for Glock G27 Gen 5 pistols chambered in 40 S&W, with a 9-round capacity.

Construction & Reliability

Glock magazines are engineered for dependable performance. Each magazine features:

• Hardened steel insert encased in high-tech polymer for durability and protection against deformation
• High-quality spring and follower that ensure reliable feeding from the first round through the last shot
• Double-cut magazine body compatible with Gen 4 and Gen 5 Glock pistol models with reversed magazine catches
• Orange follower for easy visual identification

Break-In Period

New Glock magazines may require a break-in period before reaching full capacity. This is normal. We recommend:

• Loading the magazine with all but the last round and allowing it to sit for several days to compress the spring
• Cycling the magazine from full to empty multiple times to accelerate the break-in process
• The final round may not fit until the spring has been properly compressed

This is a factory Glock product built to the same exacting standards as Glock pistols themselves.
