Based on the pictures I have seen the DRC Glove Loop Lever appears to be smaller than the WWG Big Loop Lever, which is a little more extreme in appearance. I guess you could say that the WWG is closer in appearance to the Winchester "John Wayne" style lever than the DRC Glove Loop Lever. The one WWG lever that I saw on one of their takedown custom jobs looked a bit bigger than necessary for use with thick gloves.
I plan on getting 2 DRC Glove Loop Levers in the future for my Marlin 336D and my 1895GS.
Hope this helps, :-)
