Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Fully Checkered For A Firm, Nonslip Grip

Get a solid grip on your Govt. or Officers Model with the crisp, clean 25 lpi machine-cut checkering on these all-steel mainspring housings. Helps improved accuracy by keeping the pistol correctly positioned in the shooting hand for a consistent hold and improves recoil control. Great for combat or competition pistols. Flat (FL) model offers a clean, low profile that lets you get a good, solid grip. Arched (AR) has the bump or rounded swell toward the bottom of the housing that aids in maintaining a higher grip. Magwell (MW) model combines the flat housing with a separate, enlarged magazine well that helps speed magazine changes. Magwell removes easily for carry or other times when a low profile is required. Ball bearing detent eliminates play for solid contact between magwell and housing. One-Piece Mainspring Housing/Magwell is machined from a solid billet of steel for an exceptionally solid fit and feel. Flat, with precise, 20 lpi checkering only where your hand touches the back, and a rounded bottom to minimize risk of print-through during concealed carry. Available with or without a lanyard loop.
