I found a good flashlight that could be used for a mod . It is metal and comes apart easy . The end cap will fit on either end of the grip so if you had two of them that would solve the problem of end caps for a small mod at least . http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260755126962&ssPageName=STRK:MEWNX:IT Here are some pics
