Old school cheques work very well.
It is a long winter up here in Michigan i just pulled the factory trigger out of my np2 and digitized it on a CMM machine, i am going to wire burn a half dozen out of a piece of S7 tool steel and try experimenting with the geometry of the trigger angle on the top of the trigger and see if i can get a really good first and second stage to my liking. If i come up with anything that is worth mentioning i will post it.I am a tool and Die Maker, and have been tinkering with rifles and pistols most of my life, I have edm ported many of my guns and pistols, did lots of trigger work, just finished a couple of Ruger sr9 triggers. just got back into air guns because of the lack of 22 shells and the ridiculous cost of them now if you do find them.
