Glock Mag 10 round limiter

thingiverse

This is a high-capacity magazine limiter designed specifically for Glock 19 style magazines, limiting the capacity to just five rounds. To install this limiter, you'll need to carefully remove the base plate from the magazine first, followed by the small plastic piece that sits between the base plate and the spring. Next, insert the limiter directly through the middle of the spring, taking care not to touch or compress the spring in the process. Finally, replace the base plate securely, ensuring a snug fit.
