Just a note here for the A22 (and B22) - to get a lighter trigger pull you can heat the T-spring with a lighter - red hot- and let it cool slowly. My A22 trigger is about 2#; the B22 is 1.4#. And I made a Trigger 'adjustment tool' with a 6-7" piece of hanger wire, cut a slot on the end to catch the T-spring cross-piece. The 'tool' that comes with the gun won't reach thru the trigger guard of the A22. For the B22 I drilled thru the guard to adjust w/o taking the rifle apart.
