I preface by saying that I am not a gunsmith, and am not educated in engineering, machining, or any such field (actually a liberal arts 2-yr degree is all I've got to my name.) Take this advice with a grain of salt, your idiocy is not my problem (but we can be idiots together if you'd like.)
I recently had some trouble finding information on doing a .22 lr Remington 597 trigger lightening, so here's the long and short of it.
From factory the trigger was measuring about 6 lbs by the good ole fishing scale. I disassembled the trigger housing and polished the hammer pretty extensively, just remember that the goal is not to remove material so much as smooth it, using 400-600 grit wet or dry and some oil (clp works too) pressed against a flat surface. Do not alter the angle of the sear catch, but it is ok to very slightly round the factory edge. If you are in any way shape or form unsure of what you are doing, take this to a professional, I am mechanically inclined and intimately understand the relation of each part prior to modification.
This will bring you to around 5lbs, but will serve to smooth the pull considerably.
From here, you can take the next step of disassembling the trigger return mechanism, which sits at the bottom rear of the housing. You will notice a thin gauge spring with 4-5 coils. This is the return spring, which (you guessed it) returns the trigger to firing position. This spring can be removed and half of a coil snipped. Then use a set of round nosed pliers to re-create the factory loop and reassemble everything.
By this method, I have been able to achieve around 4 lbs, very smooth, with no pre-travel. This has not affected my hammer throw and ignition reliability is 100%. I have extensively dropped tested with and without the safety on, and cannot cause the hammer to drop without physically pulling the trigger.
Good luck, and be safe.
