Sorry I haven't worked on one of those yet. Most triggers can be made to function well at around 3 pounds and that, if smooth, is a very controllable weight. If you wish less you are probably looking for competition grade triggers. I would contact M.H. Canjar Co.6510 Raleigh St.Arvada, CO. 80003 . I have never found a website for them but if a trigger is available they may be able to help.
