Is it easy to improve DA pull smoothness on S&W 6904 (3rd. Gen.)?

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.

Dry firer it at night with snap caps It will smooth out ; ) PS If you do "Polish" or change springs, save the original parts

Didn’t know how many hundreds of pulls might smooth it out.

At least the Israelis didn’t use it enough to degrade the appearance, and never allowed fine sand to penetrate it.

Thanks

GUNSMITHING THE S&W 3RD GENERATION PISTOL VIDEO 2 OF 4 - YouTube

Truly superb 3rd. Gen. videos by this gent.
Total disassembly, reassembly, even explains sandpaper vs. his (depicted) Arkansas stones etc.

The drawbar was shown in the gun before it was removed and then rubbed with 220 grit sandpaper, possibly finer also, and "Mother's wax" or such. Quite smooth and shiny after his well-depicted/illuminated process.
His explanations and rationale seem perfectly matched to the actions performed.

The very clear disassembly of each component in the frame and slide, plus later reassembly must be incomparable. The guy must be a trained S&W gunsmith or otherwise must be extremely seasoned with handguns.
