What’s Included:
- 1 × Extended base pad (141 mm)
- 1 × Eemann Tech extended magazine spring for Glock magazine (music wire, heat treated)
Installation instruction:
- Confirm the firearm is unloaded. Work on a clear, safe bench.
- Hold the Glock 9mm magazine body upright with the feed lips facing up.
- Insert the Eemann Tech spring with the connected follower into the magazine body. Ensure the front face of the follower matches the feed angle.
- Slide the ET-120033 base pad onto the spring from the bottom until it contacts the magazine body.
- Maintain light upward pressure on the spring. Align the base pad rails with the magazine body grooves.
- Rock the base pad side-to-side gently and slide it forward along the rails until it snaps into the locking notch. Do not force it.
- Check the witness holes. If the spring appears misaligned, remove the pad and reseat the spring so it sits squarely in the base pad pocket.
- If the base pad resists locking, slightly compress the follower using a finger or a soft, non-marring tool while guiding the pad into place. Keep pressure centered on the spring.
- After the base pad locks, gently shake the magazine. Ensure the follower moves freely and that there are no loose parts or rattling.
- Load rounds one at a time up to the intended capacity. Confirm smooth seating and full follower travel.
- Ensure the magazine fits and locks into the pistol without binding. Perform unloaded dry-function checks only.
