Quilly,
go to
www.marlinfirearms.com , then go into "marlin talk" , then go into the "big bore" forum. Do a search on timney triggers. It seems Timney has been working on one for your gun and it should be available by the end of September. This is a really awesome forum for Marlin shooters. Why...it's almost as good as this one <img src=icon_smile_big.gif border=0 align=middle>
