Can't speak for the 4" CIA, but for a bobbed, shrouded, otherwise long pull trigger, it is a long, albeit smooth pull. The mechanics have take up to rotate the cylinder, and the break is predictable, and consistent, every time.
Your right, it's no Colt Match Grade. Neither is my Kel-Tec. Best guess is a 6-8+ pull. but for a Taurus, whether mousegun, snub, or 4" it is a SD pistol, not a tack driving match pistol.
It simply works, considering, the long pull "is" the safety, for a SD or carry pistol, that's a good thing. One can always tweak it, fluff & buff it, but it's a Taurus. It will go bang when pulled. If drawn for SD, when a BG is in your "space" 4,6,8 # won't even be relevant, as long as it works.
"IT" guys, web designers, make websites....not nitty gritty details of what discerning folks want to know.
