The pull isn't bad at all, but doesn't compare with that on my S&W 908, Sig P225 (German-proofed) or CZ PCR. --I've never learned how to polish a sear on any gun, and it would only involve >> rubbing by hand<<. If an amateur could do this without too much disassembly of frame components or trouble (Youtube), then it might be practical. Youtube seems to have nothing about improving (1) trigger bars, or (2) sears for any 1-3rd. Gen. S&W guns. My conclusion is that it requires the techniques of only experienced people.
