I have a Viper adjustable leg holster which is big enough to cope with the TM Mk23, less the LAM. One of the few pieces of Viper kit I would say is worth getting and not very expensive. If I carry the Mk23 in the holster I do not generally have the suppressor fitted though. There are some older topics about this or the Mk23 if you try searching, which is how I found out about it in the first place. The Viper holster was recommended to me by one of the other Mods, although this was before the one sold by Socom tactical.
