It's no secret that enclosed, complicated triggers can get futzed up by stuff, and obvious that simple ones are less prone to that, no side-by-side scientific testing needed. Still, I have a several Timney's now, plus Howa factory that serve me well and have great pulls. Same is true of my sole remaining Ruger LC6 (out of the box), and the old M70s I've used. Whatever works, works. Have a hard time with oogly though.
