Femme Fatale Airsoft got this review on a TRMR Holster from Mile Gear... "This post is all about my current TRMR holster – the Mile Gear V1 Kraken Kydex TRMR carrier from JD Airsoft. If you’ve been a follower of FFA from the start you will know that I’ve had at least one of every generation of TRMR, the Tactical Reloadable Maritime Ready blank firing grenade, all in pink of course by Concept Tactical, of which you can read my review here.
RandomTrashy checks out the TRMR E1 Impact Grenade that can be used in airsoft or milsim events, provided that your local site allows for it... "The T.R.M.R. is an ergonomically designed reloadable device that utilises a twist to arm inertia recoil firing system. This allow for safe, fast reloading of the device without the need for levers and pins as used on conventional hand deployed devices."
