the ruger manual has very good disassembly/reassembly instructions....you can do a good trigger job by just disassembling,study the trigger and transfer bar assembly to see how parts interact and polishing these parts...get a assortment of hammer springs and trigger springs,polish up the parts(i've done three guns and didn't touch the hammer/sear engagement)..try various spring combinations and you can get a nice 2 1/2-3# trigger.....don't be afraid to give it a shot
