OK I changed out my trigger from stock to a Jewell tonite. I think I have the first and second stages adjusted to suit me. I'll need to shoot it some before I make any more adjustments.

One question though. That 'screwdriver' looking tool was useless, couldn't use it for any adjustments. I had an allen wrench that worked for the large screw (second stage) but I wonder what size the 2 small ones are [:\]

The 'hook' thingy was OK for moving the first stage spring around though...

The small one is 1/16". Here are some better instructions than the ones that come with the trigger.

Thanks, after reading the supplemental instructions I realize I installed the trigger spring wrong - I put the L shaped leg on the adjustment plate, its supposed to be under the trigger rivet....OPPS!
