I am astounded at how much focus people have on trigger pulls. When one is in a crisis, pumped with adrenalin, three times stronger than normal and frightened half to death, the trigger pull means nothing. Focus in your practice on the target, and putting rounds into it in the right places. When I practice shooting I do not practice target shooting. I imagine an opponent trying to kill me, and I focus on putting rounds into that opponent. I hype myself and I can shoot with any trigger at that point. Target shooting can be fun, and helpful in some ways; but it is almost the antithesis of self defense. Point shooting, shooting over the sights, or bringing the sights in line quickly are the important issues. Putting your rounds where they belong does not require a tuned and soft trigger. It requires focus on the target and drilling in panic mode.
