KRISS MAGEX2 KIT FOR G21 17RD 3PK

Magazine extensions reshape how operators manage capacity on duty and sport pistols. The KRISS MAGEX2 kit delivers a practical solution for G21 users across the San Jose area who need extended grip real estate. California shooters should review California's 10-round magazine limit before selecting any magazine accessory to ensure compliance with state law.

Extension design and grip ergonomics

This three-pack kit uses proven extension geometry to add grip length and material contact surface. The MAGEX2 design integrates with standard G21 magazines without requiring permanent modification. Proper fit depends on your specific pistol model and magazine type.
