I have been using the V21 Q.R. model Nylon holster for over 10 years. Not the same one :ohgeez:but the same model. :twothumbs I have found that the more you use this holster, especially with the new lights like the E2D LED Defender, the faster it will wear as the tailcap edge will cut into the Nylon base. If you have a 6P or Nitrolon model the holster will last longer, again depending on usage. Personally, I wont use anything else and have used both the V70 (Moulded for 6P/G2) and even the V27 Leather belt holster. I like the ability to quick attach it to my trouser belt as I leave home and the flexibilty it provides whilst performing my duties.
