Midway sells a sear and spring kit that will reduce pull weight and smoothen the trigger of the 77/22. You use your existing trigger, so it will not be adjustable. Instillation is a snap. There is one pin you need to punch out to remove the sear, remove the factory spring, put in new spring, put in new sear-very easy to understand once you have the action out of the stock. Now, the tricky part. The new sear and spring will probably change the fit between your trigger and safety. You will have the safety in the "off" postion while installing the sear and spring and probably won't be able to re-engage the safety. You need to slowly, with a file, take material from the shoulder of the trigger (you will understand what I am saying if you look at how the turret of the safety contacts the trigger shoulder and then allows the trigger to move (fire) when the safety is pushed to forward most (off) position), if you remove too much material from this shoulder on the trigger, it will allow enough movement for the trigger to release the sear with the safety engaged, or while closing the bolt (slam fire). I speak this from experience. I bought a Timney trigger for my Mark II (same set up as 77/22, just different sized parts) and bunged up the adjustable Timney trigger by taking off too much material. I put the factory trigger back in, and with the Timney spring and sear, got a consistant 2 3/4 lb release, although I lost the capability of adjustment, but that is about the weight I was going for. Hope this helps.
