Glock Dry Fire Mag with Spring Kit included — fits 9mm (G17, G19, G19X, G26, G34, G45, G47, G49), .40 (G22, G23, G27, G35), .45 GAP (G37, G38, G39), .357 SIG (G31, G32, G33), .22 (G44) in Gen 3, 4, 5, 6, and V Series

No slide racking between trigger presses — practice double taps, multi-shot strings, and draw-to-fire drills with both hands on pistol, sights on target. Break and reset closely simulate live fire; included spring kit tunes pull weight 3 to 10+ lbs.

Spring kit included for trigger weight adjustment. Out of the box, this dry fire mag simulates a factory Glock 5.5 to 6 lb pull. Swap springs lighter for competition training or heavier for concealed carry practice — tunable from 3 to 10+ lbs.

Mechanical trigger reset tool designed for Glock small-frame double stack models. Not compatible with 10mm or .45 ACP large-frame Glocks, single-stack G43X/G48, firing pin-activated laser cartridges, or some laser training systems.

Dry fire mag with built-in trigger reset for building shooting fundamentals without live ammo. For Glock Performance Trigger or other custom triggers that return forward to the cocked position, remove the spring for a more natural press.
