A heavier base pad drops the P226 magazine cleanly after the release and closes the magwell funnel at the bottom when a magwell is fitted. The P226 is a full-size metal-framed DA/SA 9mm, and its magazine uses a Sig-specific double-stack design. In competition, where the reload follows the last shot under stage pressure, a base pad that makes the magazine exit reliable and the magwell funnel complete is a meaningful improvement. The P226 and P226 X-Five share the same magazine.
The P226 magazine is not compatible with P320 base pads. Confirm on the individual product page before ordering.
