No offense, FM, but I am losing interest in posting in this thread. It seems I just get excuses for why an idea of mine (and others) won't work rather than how to make it a possibility.
I like some of your stuff for SF, but I would like to see more.
I don't like pink flashlights.
I don't care for 100 different ways to machine a maglite body.
Some of the ideas in this thread would fill a need for products that do not exist.
How about a delrin tailguard for a Z58 tailcap? I could list many more, but generating ideas here seems a little fruitless to me so far.
