In order to clarify my previous post in re: "Unsatisfactory Triggers", let me offer the following definition, using S&W double action pulls as an example:
1) "Excellent": Light pull weight (less than seven pounds; in some cases much less), free of any hesitation, grit, or stacking. Will probably only ignite Federal primers. Only really suitable for competition. No hammer spur or single-action capability retained. Costs a mint.
2) "Very Good": Light pull. Requires spring kit and extensive polishing and stoning of various mating and bearing surfaces. As light as you'll want for anything that requires 100% reliability.
3) "Good": Smooth-ish pull. Somewhat lighter than stock. Some spring replacement required. Some attention paid to hand & star. Only trigger job you can get for less than $50 from most gunsmitheries.
4) "Adequate": Found on well-broken-in older Smiths and some Performance Center guns.
5) "Unsatisfactory": Everything else. Why we have in-house gunsmiths.
Yeah, I'm a gun snob. So sue me.
