HI BW, if not too late to reply, when stripping trigger action did you check the spring in the front of trigger (the one the holds the sear lever) these can build up and/or weaken. very hard to get this apart as the trigger is muck metal and the small pin is just a cut wire normally. The trigger will break if you punching them out. i use brake cleaner under pressure to clean these type of bits.
PS i have boxes of stirling parts and always buying/selling 22's. Currently in the process of 3D printing these triggers/assemblies. (as lots of people have broken them when disassembling) hopefully have them for sale prior Xmas....
