Awesome light - EOTech M2 UTL Weapon Mounted Universal Tactical Light for H&K USPs HKL-000-A5

While this light is very easy to use, its pretty limited on its functions. 90 lumens with only a 60 minute run time. HK was right on using the non-trigger finger for operation, but its only for right handers. I recommend the LED upgrade, it will give you more lumens with a longer run time.
Pros: Easy non-firing finger operation
Cons: Short battery life
