Wilson Combat Bullet Proof One-Piece Magwell, Full-Size Round Butt, Aluminum

The Wilson Combat Bullet Proof One-Piece Magwell (Wilson Combat part no. 627ARB) is a machined aluminum magwell built for a full-size, round-butt 1911 grip frame. Wilson Combat is one of the most respected names in match-grade 1911 pistolsmithing, and Bullet Proof is the company’s designation for its upgraded, higher-spec parts line. A magwell flares the bottom of the grip frame to funnel a fresh magazine into the well, speeding up reloads under time pressure, and this version is built as a single piece rather than a bolt-on add-on funnel.

Key Specifications

• Built for a full-size grip frame with a round butt profile rather than a square butt.
• Machined from aluminum, keeping added weight to a minimum at the base of the grip.
• Part of Wilson Combat’s Bullet Proof line, the company’s upgraded, higher-spec parts designation.
• As a one-piece magwell, it integrates directly into the grip frame rather than bolting on as a separate funnel.
• A flared magwell funnels a fresh magazine into the well faster, which matters most under time pressure.
