Easy Install Upgrade for Faster Reloads and Improved Grip
Designed for competitive shooters, tactical users, and anyone wanting a more efficient reload, the Herrington Arms P320 Magwell provides a flared opening to guide magazines in faster and more consistently under pressure. Herrington specifically designed this magwell to be different than other magwells but adding relief cuts allowing Sig OEM base plates to sit flush in the magwell. This allows users to carry as short of a magazine as possible while concealing carrying without losing any functionality.
Features
- Low-Profile Design – Improves performance without excessive bulk or snag points.
- Easy Installation – Installs quickly without the need for major modifications.
- Ideal for Competitive, Tactical, & Defensive Use – Designed for reliability when it matters most.
- Improved Grip – A flared magwell make a nice stopping point for preventing shooter’s hands from slipping down the grip.
- Precision-Machined Aluminum Construction – Lightweight 6061 Aluminum yet strong enough to withstand heavy use.
