my Margolin's.22 pistol trigger weight is 2 kilos how can I reduce to 1 kilo

You can bend the trigger return spring to reduce some weight. Also some sear/hammer polishing will help (but don't do this unless you know what you are doing).

If you are handy at metal working and you don't need to keep your Margolin in pristine, collectors' condition, you can carry out the mod shown below, taken from AP Danilov's (gunsmith to USSR shooting teams) 1968 book (you remove the existing trigger spring); if you get the right type and size of spring steel (cut-up hacksaw blade?) you can make the weight adjustable around 1000gm:



Alternatively, if your trigger pull is too long, you can shorten it as shown below (ibid) by hammering the trigger bar with the pein of a hammer between the upright part (the disconnector) and the notched LH end, or you can make a new trigger bar. This will then just employ the softer initial movement of the trigger though it won't get you down to 1000gm:



I have done neither of these myself though one day I probably will, along with a few other Danilov mods. (http://toz35.blogspot.com.au/search?q=danilov)
