Glock 30821 Gen4 Backstrap/Beavertail Set Black Polymer

The Glock 30821 Backstrap/Beavertail Set transforms grip ergonomics on Gen4 pistols, providing customizable hand fit and enhanced recoil control. This factory-engineered polymer system addresses the most common complaint about stock Glock frames - grip angle and size incompatibility across different hand dimensions.

What Makes This Different

Unlike aftermarket grip modifications that can void warranties, this official Glock accessory maintains factory reliability standards while delivering measurable ergonomic improvements. The modular design allows shooters to fine-tune grip circumference and backstrap angle without permanent frame alterations. Independent testing shows up to 15% reduction in felt recoil and 20% faster follow-up shot times when properly fitted to individual hand geometry.
