To bring it back to the first post, I shoot dots and irons, I've had both fail. You know what I carry? P365 SAS. It's annoying and I should train a lot more and I'm sure there's some way it could fail, but the front sight can't fall off, the battery can't die, and I have more than 5 shots. Do I like it? Not really, but it's the best tool for the job in my opinion. Eliminating failure points is key, and one of those ways, as has been mentioned, is training. I need to do more of that, and that's probably always the case.
