Hogues LE Grips have a fully programmable, digitally-controlled microprocessor circuit. Hogues designers capitalized on this advantage by programming three operating modes steady, flashing, or stealth target and four user-selectable intensity levels into the LE Grips circuit. They also tapped into sophisticated power management routines to ensure long life from two common CR-2032 batteries hidden under the grip on the non-laser side an important design feature enabling battery changes that dont take the laser out of zero. Each LE Grip is bore-sighted at the factory while fine windage and elevation adjustments are available via small set screws. All of the Hogue LE Grips programming features are accessible via pressure-sensitive programming buttons on the grip.
