PCC magwells funnel magazines into the lower receiver faster under the stress of a competition reload, reducing the indexing precision required during rapid magazine changes. Flared aluminum or polymer designs thread or pin onto Glock-pattern and Colt-pattern lowers, providing an expanded entry cone without adding meaningful weight. Critical on stages with mandatory reloads or limited-round strings that force a reload under time pressure. Fast same-day shipping on most orders at Shooters Connection.
