The trigger is the most important part on a pistol. A 12lb trigger is much harder to control, than a 4.5lb one, as on my Glock 19 4th gen, carry/IDPA pistol.
The most accurate shooting sport, re pistol, is free pistol. Trigger weight? 1lb?
Single shot, 50m target.
Think of this, you are shooting for score, using sights, 12lb trigger or 4.5lb one?
That was a no brainer, yes.
