Might be an issue on a slow, deliberate, range day or in competition
You can generally tell people who’ve never shot competitively because they imagine that competitors don’t get adrenaline dumps, tachypsychia, sweaty palms, shakes, etc. If they take competition seriously, they’ve definitely experienced those things.
Moreover, the performance benefits of good triggers aren’t limited to how they subjectively feel. The more force you have to apply to a trigger, the more any misdirection of that force from straight back will alter the direction of the muzzle.
Competition measures shooting performance very well. It doesn’t measure things like tactics or descalation or physical courage or threat discrimination. But if something improves shooting performance in some dimension in competition, there is no reason not to expect a similar improvement in other contexts.
There may be other, countervailing reasons to not do some performance-maximizing thing. I can deliver a better shooting performance using my USPSA open-division gun, but I can’t really carry it around in regular life. So I make a conscious performance compromise.
