Hi PureBlue 146...welcome to the CPF!
I`m not a law enforcement officer, but I can gladly share the following observations with you for whatever they`re worth:
1) I`ve purchased three of the 10X911 kits from William at Texas Tactical Supply...one for myself and one for each of my two sons.
2) The 10X is a truly well made flashlight, with a bright beam of light that is nothing short of spectacular. (I use the MN31 and MN32 lamps...that being 440 lumens and 110 lumens respectively...for a total of 550 lumens.)
3) My oldest son was just sworn in as a police officer for the City of Atlanta Police Department, and I`ve sent his 10X to him. It`s my understanding that he carries on his duty belt an Ultra Stinger flashlight that is issued by the department, but that he keeps his 10X (along with an M6 that I also sent to him) in his gear bag so that he can use it for traffic stops, etc.
3) Two minor shortcomings as I see it: (i)If you need a flashlight that can also be used as an impact weapon, then the 10X would probably not be the best choice...it would appear to be too fragile for that type of use, and (ii) although they`re apparently working on it, I`m not yet aware of any holster to use for carrying the 10X.
Notwithstanding those two shortcomings, though, IMHO the 10X, along with the M6, are simply two of the best and brightest flashlights ever made, and are at the very top of the legendary category of "must have" flashlights.
Best wishes to you!
