Larry, do you (or anyone else) know the spec for the factory strain screw length? I have yet to fire the gun after cleaning the internals, but I would appreciate as much information as possible. I kind of consider it the 'ammunition' for that weapon inside my skull.
9.3x62, thanks for the rundown. There is a good chance that the previous owner swapped springs or screws or something. Hopefully this thread will help me get to the bottom of the matter. What the guy behind the counter told me, as I was purchasing this m19 (in favor of a blued 6" m28, same price...shoulda bought both) was that an old fella had come in with a pile of classic smiths for consignment. Not sure what this says about likelihood of trigger lightening, maybe nothing.
