I replaced the stock trigger on my SA loaded with a 10-8 flat trigger. First, I fitted the trigger itself & had to take a little material off the shoe for fit. The new one is now fit tighter than the stock one. No side to side play and very, very miniscule verticle play (again, less than the stock trigger).
Then, I replaced all of the other ignition parts too. C&S disconnect, sear, hammer, sear spring and mainspring. I was extremely careful as I do understand that the tolerances are close and deviation can cause extreme safety issues. I ran through all of the firing tests. First running five consecutive mags with two, then three, then four then five rounds each. I had no misfires or any uncontrolled full-auto issues with any of this. I have since run a few hundred rounds through the gun normally (using fully loaded 7 round mags).
While this was all tedious and I was extrememly careful - I can also promise you that it was not all that difficult either - in other words, I ain't no brainsurgeon :-)
