Glock 50980 Magazine Insert 10mm Gen4 Glock 20/29SF Black Polymer

The Glock 50980 Magazine Insert transforms standard Glock 20 and 29SF magazines for optimized 10mm Auto performance. This factory component addresses feeding reliability issues common with high-pressure 10mm cartridges in Gen4 platforms.

What Makes This Different

Unlike aftermarket magazine modifications, this genuine Glock insert maintains factory tolerances and reliability standards. The precision-molded polymer construction provides consistent cartridge positioning that standard magazine followers often struggle to achieve with 10mm's varied case geometries. Independent testing shows improved feeding reliability by 15% over unmodified magazines, particularly with flat-nose and hollow-point ammunition.
