To each it’s own, but I buy firearms solely for self defense whether it be for the home or while out in public. Not for sport. Sure, I’ll take it to range every few months to practice with it, but If put in a SD situation where I have to fire it, do you think I care whether its a 4lb or 5lb trigger? Do you think I care about how long the travel or reset of that trigger is? No. I am going to fire it regardless until that threat is eliminated.
I never understood the fascination with a firearm’s trigger outside of competition/sport shooting. Am I missing something?
Stress is great at degrading accuracy. So is speed. Unless you have practiced shooting under stress at high speed, you don't know how bad you will be at being able to hit the target. Sadly true for most people, who utilize firearms in the way you describe...woefully deficient in the application of the fundamentals of shooting, when they are needed most.
Having done several shooting reconstructions as an expert, it is apparent that a moderately trained person is going to triple or more their "range qualification" group size. Some a lot more. Highly trained, practiced folks are going to see significantly less increase in group size.
Now, add in a poor, heavy trigger to the poorly trained person, which is a compounding effect. Yeah, that is not going to result in hits on target at any reasonable distance. It is one reason that folks who understand harp on regular practice just to maintain skills. A huge percentage of the folks in the US who carry a handgun are very unprepared to use it successfully.
The whole intent of practical competitions (IPSC and 3Gun originally) was to give people a format to practically use their firearms at speed and under stress. They have turned into games more than arenas to prove proficiency. Sad, but true.
