The Crimson Trace Lasergrip for Glock Compact Size (LG-639) is a rear-activated laser sight engineered for third-generation and modern Glock compact platforms. Featuring Crimson Trace's patented Instinctive Activation technology, the laser activates automatically when the shooter assumes a normal firing grip—eliminating the need for external buttons or conscious activation. This design philosophy reduces cognitive load during dynamic shooting and is favored by law enforcement and defensive-oriented shooters who prioritize speed and instinctive response.
The LG-639 attaches directly to the grip frame without gunsmithing, securing in moments with no permanent modifications to the firearm. The laser sight is fully adjustable for both windage and elevation, allowing precise zeroing at distance. An integrated Master On/Off Switch enables complete power-down when the sight is not in use, extending battery life. The compact form factor and low-profile design maintain holster compatibility across a wide range of Glock-specific duty and carry rigs, making this sight practical for operators who rotate between multiple carry systems.
This platform is optimized for concealed carry, off-duty use, and tactical training where rapid target acquisition is critical. The compact Glock 19, 23, 25, 32, 38 (third generation), Gen4 19/23/32, and Gen5 19 models represent the most widely carried duty and personal-defense pistols in North America, making the LG-639 a practical upgrade for agencies and individuals seeking to improve point-of-aim confidence without adding bulk or weight.
