Front Strap Checkering

Front strap checkering. First the front strap is measured to ensure it is thick enough so the serration cuts don't break through the front strap. A minimum of .065-.075 thousandths of an inch is required. Then the front strap radius is trued to eliminate any low spots that will create flat or lowered checkering points and the under cut for the trigger guard is machined in at the same time. Then the horizontal and vertical serrations are machined in at 20, 25 or 30 lines per inch
