LaserLyte proudly introduces the CK-MS for the popular personal defense pistols, the Bersa Thunder .380 and .380 Plus. The laser is easy and quick to mount on the Bersa trigger guard and snugs-up securely to the dust cover and simple to activate with the ambidextrous, ergonomic switch. The LaserLyte CK-MS laser is easily programmable to either constant on or pulse mode. Another great feature is the “auto-off” feature that displays a unique flash after 5-minutes of operation and automatically turns the unit off after 6-minutes.
