Great compact light! - SureFire XC1 Ultra-Compact LED Handgun Light

Long story short: Bought 2x XC1 because 1x had to be exchanged due to it having parasitic battery drain. Exchanged it because of Optics Planet has excellent customer service!
End: The XC1 is a great compact light!

Originally bought the XC1 because I didn't want the holster to be overly large when I was carrying my G19 with Surefire X300 appendix in the waistband. Found a smaller option: XC1. The lumens compared from the X300 to the XC1 is more than half, but sometimes more is not better. After I received the light and installed it to the on to the pistol, I turned it on to do a operations check. Less than 3 days later, even with the fresh factory provided lithium double A battery, the light would deplete the battery. Swapped out the battery to a new one, then next day, it would be dead. I didn't think a few operation checks from time to time would justify the battery dying so quickly. Got online and did some research. Found some forums that spoke about it the parasitic drain on the battery. Contacted Optic's Planets customers service via online chat and was able to send the faulty XC1 back and have it exchanged quickly.

The new XC1 came quickly, and was installed quickly. Factory provided lithium battery installed and operations checked again. Every few days I would continue operations check it, the light hasn't died or drained any batteries yet!
