This is a good tactical light if you are using Blackhawk Serpa Light bearing holsters. Blackhawk holsters offer excellent weapon retention depending on the security level you select. Light must be ordered for the primary shooting hand and is not switchable. This is primarily for the Blackhawk holster fitting. Very good Blackhawk customer service for backup parts/screws ect.
Pros: Retention
Cons: Not ambidextrous
