Frequently Asked Questions
Gen 2 Dry Weight Magazine InsertWhat is the Gen 2 Dry Weight Magazine Insert?The Gen 2 Dry Weight is a realistic magazine-weight simulator for dry fire practice. It replicates the weight, balance, and insertion resistance of a fully loaded magazine—without the use of dummy rounds or live ammo. This generation includes an internal spring to simulate compression resistance and a modular bullet-shaped topper that mimics the feeding geometry of a live round.What does it come with?Each unit includes:
- 1x Weighted insert body
- 1x Magazine springs (5–6 coils each)
- 2x Bullet-shaped topper (one installed on the body, one spare)
- 1x Flat Top topper. This item sits low enough to not engage the slide and allows easy racking, or use in combo with a snap cap for racking of a round into the chamber
How do I install it?
- Disassemble your magazine: Remove the base pad and take out the factory spring and follower.
- Insert the Dry Weight unit:
- Insert it spring-side down (toward the base pad).
- Make sure the bullet topper is pointed toward the muzzle, as a live round would be.
- Reattach the base pad as normal.
How do I adjust spring tension?You may trim the spring coils to fine-tune the resistance or make the same insert body work in multiple magazine sizes. Cut one coil at a time until you’ve achieved the desired performance
- For shorter mags (e.g. Glock 17 w/ no extension), use fewer coils—typically 2–3.
- For extended mags (e.g. 140mm USPSA mags), use the full spring or trim to fit—usually 5–6 coils.
Can I use this in different magazines?Yes. The modular spring system allows you to adjust spring length and tension for compatibility across multiple magazine sizes. If you want to repurpose your insert for a different mag, simply change the spring length as needed.Will this affect slide movement?Yes—depending onyour spring tension setup:
- Thebullet-shaped topperis designed toblock the slide from moving forward, simulating a locked-back condition. It mimics a chambered round but cannot be fed, so it halts the slide.
- However,if tuned properly(using fewer spring coils or reducing spring tension), it is possible torack the slide with the bullet topper installed.
- Your mileage may vary, and minor tuning may be needed depending on your specific firearm and magazine dimensions.
