A magwell widens and chamfers the magazine well opening, giving the incoming .40 S&W magazine a larger target at the entry point. Under stage pressure, a more forgiving funnel reduces the margin for error on the reload. The 96 uses the 92 frame in .40 S&W, and its magazine opening geometry may differ slightly from the 9mm 92 variants. A compatible base pad is required to close the funnel. Confirm the 96-specific combination on the individual product page before ordering.
