3. I was once at a class where a guy kept crowing about his custom deathray brand pistol which could hold 2 inches at 25 yrds all day long. At some point after hearing that phrase multiple times, somebody said, SO WHAT, YOU CAN'T."
If you can hold, 90% + of your rounds fired on an 8.5x11 sheet of paper at 25 yards, then triggers, different non RDS sights and/or barrels may give you some benefit. Unless and until that is true, particularly in striker fired platforms, it is a software problem looking for a hardware solution.
Some might even say the accuracy standard should be the black of a B8 before one should start fitting barrels, swapping triggers etc.
IMHO/YMMV
