Crimson Trace's latest Lasergrip sighting system for Beretta Vertec pistols features third-generation improvements that help the Beretta perform at an even higher level. Like all Lasergrips, Vertec grips feature what Crimson Trace calls "instinctive activation." Oversized buttons strategically located on both sides of the grip ensure positive activation for both left- and right-handed shooters. With this approach, all the shooter has to do is assume the firing position. No other steps are necessary. The Lasergrip design provides the space to locate dual lithium batteries within the grip panels. The ample power supply allows Crimson Trace to use a bright, continuous beam for maximum visibility and speed. These batteries deliver over four hours of constant run time and five years of shelf life.
