I just got my 2240 in this afternoon. I already had the supersear, and a steel breech came in earlier in the day via USPS. I changed out the breech for starters, then installed the supersear. I should have checked the trigger pull with the stock trigger, all I can say is it was heavy, after the Supersear it was about 3.6 lbs, much better. The sear does not seem to be sitting parallel in the housing so I have some shims ordered as well as one of the adjustable sear springs, so will see how that goes. While doing all of that I may slip the hammer out and polish it . This is my first airgun project and seems to be going smoothly. I'm not after hotrodding, just want smooth and accurate, and a nice trigger sure helps.
I'm also planning on modifying my 2300s with a 1701p two stage trigger, but that's for another day.
