Have you ever get stuck in the middle of a mag change with your spare mag. ready but waiting for the magazine to drop out of the gun handle?

Have you ever have to or see someone have to shake their guns sideways to drop their magazine in a match?

Think about if the above happened in a gunfight instead of a match. This magazine weight might solve the above problem for you.

Want to get a feel of how good the MagWeight works? The 1 oz MagWeight is close to two to three rounds of 9mm and two rounds of .40 S&W. The 2 oz MagWeight is close to 5 rounds of 9mm and 4 rounds of .40 S&W. Try to release an empty magazine and magazine with the above rounds and you will know the difference.



Increases weight of magazine so magazine can drop out faster during reload

Reduces chance of empty magazine stuck inside the gun handle

Reduces muzzle jump

Reduces felt recoil

Improves shooting speed and accuracy
