Strike Industries SI-G4 Modular Magazine Release - Glock Gen 4-5

The Strike Industries SI-G4 Modular Magazine Release transforms standard Glock controls into a precision-engineered interface built for rapid manipulation. This black anodized aluminum component replaces factory polymer releases with machined durability and enhanced ergonomics. Compatible with most Glock Gen 4 and Gen 5 pistols, the SI-G4 addresses the common complaint of insufficient leverage on factory magazine releases.

What Makes This Different

Unlike standard polymer releases, the SI-G4 features a modular design with interchangeable button faces to accommodate different hand sizes and shooting preferences. The aluminum construction provides consistent actuation pressure across temperature extremes where polymer components can become brittle or soft. CNC machining ensures precise tolerances that eliminate the play and flex common in factory releases, resulting in more positive magazine drops during reloads.

Key Features

• Black Type III hard anodized aluminum construction resists wear and corrosion
• Modular button system allows customization for different hand sizes
• Enhanced surface area provides 40% more contact area than factory releases
• Ambidextrous operation supports both right and left-handed shooters
• Drop-in installation requires no permanent modifications to frame
• Textured button face prevents finger slippage during rapid reloads
• Compatible with most Glock Gen 4 and Gen 5 models (9mm, .40, .357, .45)

Competitive shooters report faster reload times due to the increased button surface area and positive engagement. The aluminum construction maintains consistent performance through extended range sessions where heat buildup can affect polymer components. Law enforcement users appreciate the reliability in adverse weather conditions, as the anodized finish resists moisture and salt corrosion better than factory plastic releases.
