I'm looking for a new light for my usp (it's an airsoft, but a proper on, real dimensions an so on), i think the original HK USP tac light would be awesome for it, but they aren't really up to today's standards, so i'm wondering if it would be possible to upgrade it to a level where it can compete with modern pistol lights. I'd really like to put a Q5 in there, but anything >80 lumens will fit the bill.
