The Crimson Trace Corporation LG-439 Lasergrips replace the factory grip panels on the Sig Sauer P239 series with an integrated red laser sight. This is a targeting upgrade aimed at concealed carriers and law enforcement officers running the P239 as a primary or backup gun. The laser is built into a rubber overmold grip that wraps a sturdy polymer frame, so it adds aiming capability without changing how the pistol carries or handles. Front activation means the 633nm beam comes on instinctively as the shooter takes a normal firing grip, with no switch to hunt for under stress. For more red and green laser options, see our laser sights selection.
The LG-439 runs a 5mW peak, Class IIIa red laser at 633nm, projecting a dot roughly 0.5 inches in diameter at 50 feet. Power comes from two CR2032 lithium batteries, included, delivering over 4 hours of on-time use with a 5-year shelf life. The pressure pad sits on the front of the grip for instinctive activation when the pistol is held naturally. Windage and elevation are fully adjustable, and units ship factory-sighted to approximate point-of-impact at 50 feet. The grip itself weighs less than an ounce, keeps the original weapon profile, and stays slim enough to clear most holsters cut for the P239. Crimson Trace Corporation backs the unit with a 3-year warranty per manufacturer specifications.
A laser like the LG-439 earns its place in low-light defensive use, where it speeds target acquisition without forcing the shooter to fully extend or find iron sights. It also works well for dry-fire practice, showing exactly where the muzzle tracks during trigger press. Because the grip maintains the P239's original dimensions and front activation requires no manual switch, the transition from holster to threat stays consistent with how the gun already carries. Shooters fitting out a carry P239 often pair the laser with other pistol sights and aiming hardware. Browse our wider optics and sights range for the rest of the setup.
The LG-439 Lasergrips are made for the Sig Sauer P239 Series semi-automatics. They replace the factory grip panels and are not designed for other Sig models, so confirm your pistol is a P239 before ordering.
Activation is instinctive front activation through a pressure pad built into the front of the grip. The 633nm red laser comes on when the shooter takes a normal firing grip, with no separate switch or button to operate under stress.
Yes. Each LG-439 ships factory-sighted to approximate point-of-impact at 50 feet. Windage and elevation are both fully adjustable, so you can fine-tune the dot to your exact load and zero preference at the range.
It runs on two CR2032 lithium batteries, which are included. Crimson Trace rates the unit for over 4 hours of on-time use, with a 5-year shelf life on the batteries per manufacturer specifications.
The LG-439 uses a slim overmold design that maintains the pistol's original profile, so it clears most holsters cut for the P239. Holsters with tight grip retention should be checked for fit before carry.
