Purchased an '03 Viking with a JMJ Razor trigger. Found it way to sensitive and light to my liking. (I tilted the gun up to adjust the reg and it fired just from the trigger falling back on the microswitch) Any way to stiffen the pull just a little bit? I replaced the microswitch from a 35g to an 80g pull and that helped a tiny bit but the trigger still just floats freely. A friend recommend a pen spring but since stock (to my knowledge) the Viking didn't use a spring I can't think of where I would put it. Thoughts?
