Afraid I have some bad news, tonight my green laser died. I had a range session this afternoon, and this evening I thought I would get in some dry fire, tease the cat time with my 365. Pushed the button and nothing but a very, very dim green light. First thought was dead battery, so I replaced it with a fresh, out of the package new battery. Same results. I tested both batteries with a volt meter and both show 3.0 volts.
I have owned many Crimson Trace lasers since 2004 and in that time I never had a battery run down or have the laser just quit on me. Really disappointed in this happening. The poor switch operation of the Sig Lima 365 is also of great concern, so therefore I will be on the phone tomorrow with Optics Planet. First I am going to seek a refund for this defective laser. If that doesn't work I will ask for a new replacement.
I probably put less than 200 rounds through the 356 using the laser, shooting Sig 124 gr ammo. My other CT laser guns have had thousands of rounds through them without the slightest problem.
