Found thid product some time ago called "Tri-Flow". On the order of WD-40, but much much better, has teflon microscopic balls suspended. Smell good too, lol I think I got mine at Mal-Wart, but the local one doesn't carry it any more, got a bike shop to order me a couple of cans. Had a nearly full can do a full gainer off work bench and destroy nozzle. Anyway, this stuff really smoothes out triggers and safeties. On top of that, I just saw a post on Excal where one of the regulars there has discovered it. Another little tip/trick. awhile back I think it was Lee that posted about trigger shoes. They are real wide and attatch to your trigger via two set screws. the wider deal itself helps alot plus you can position one just as low as possible toward inside of trigger guard, thereby lengthening your trigger, which provides a tad more leverage and in essance lightens the pull some. Matthias 72 on Italian site and Excal made a whole new trigger for his Emax to get the above named benefits.
My bike shop got a case of 12 oz cans of Tri-Flow, if ya can't find it anywhere, pm me and I'll get ya a can in the mail. no idea on price or shipping, but it's worth it IMHO
