http://www.youtube.com/watch?v=PJfNb0PVbXU It looks pretty good compared to a Serpa? I like level II holsters and the fact that the release button is inside at my thumb vs outside at my index finger. I have always been weary with my Serpa holster when wearing it in a vehicle or when it bumps up against stuff under rough conditions like crawling ect. Not that I do alot of crawling lol. With the button inside it seems like it would be more protected from the environment and/or personal gear hitting it? I have also heard that a small pebble or twig can get lodged in the Serpa action and you absolutely cannot remove the gun with out destroying the holster. I own a Serpa and have not had any problems yet? I was just wondering if anybody actually has this new 5.11 thumb drive system and how do you like it if you do have it?
