Promag Beretta PX4 Magblock 10/17 (9mm) 10 Round Limiter

This Magblock fits the Promag Beretta PX4 17 round 9mm magazines and will limit them to 10 rounds.  Easily installed in seconds at the base of the spring. The factory locking plate is installed under the block. It is held in place with spring tension alone or can be glued or epoxied if desired. This provides an easy method to convert your Promag Beretta PX4 (Promag Part# BER-A14) magazines to 10 rounds. No external modification to the magazine is required. 

- This block is designed for the Promag Beretta PX4 17-round magazines only. They won't fit factory Beretta PX4 magazines.

*Universal Limiter Instructions: Cut to #17 and glue flush at the bottom for 10/17 limiter. Slide lock is not used. When epoxy cures assemble magazine. The two parts of the universal limiter must be glued flush to prevent the locking plate from causing the limiter to shift sideways. #17 will show in the limiter window notch like in the photos.
