I'm sorry but anyone that thinks they're going to notice the difference between a 2lb trigger and a 5lb trigger, a crisp break, or a short reset when you're in a self defense situation is silly.
Is it silly to practice more with your EDC too? Most generally would agree that practice with your EDC is a good thing that could pay a real dividend in a real shooting situation. If practice with your EDC is good, wouldn’t it make sense that tuning the guns to have a consistent feel to your EDC yield value?
The more trigger time someone gets with their EDC or a reasonably close facsimile, the more muscle memory they build. When I tuned my Glocks to have a wall that was reminiscent of the CZs (P10 mainly) that I shot, it should follow that shooting with any of the similar guns would be a benefit to shooting all of them. Sure, in my case, I was increasing the trigger pull a bit for my EDC in the pursuit of consistency, but it was still tuning for feel. When I tune my Sigs, it’s to get them all about the same for feel.
I’ll agree with the idea that it’s a bad idea to tune a carry gun trigger much below 4# unless you have experience in shooting in stressful situations. I know that I don’t and a given an adrenaline dump and shaky hands that might follow, I sure don’t want to be near a 2# trigger should I ever experience that situation.
