To me that would be the last consideration when choosing a firearm. I have put tens of thousands of rounds trough firearms of all sorts and have never had or seen a misfire using modern ammo.
That was true for me too ... until last week. Was at the range with the Boy Scouts nad one of the boys had a mis-fire. He raised his hand and asked what he should do. He was shooting my Smith 5906. I told him it's a DA/SA gun (as we had covered briefly before the outing). I told him just pull the trigger again. It went BANG on the second strike. Yea I always figured too that that's a nice sales feature but one you'll never need ... not anymore! If that was a round you really needed to have count, then a second strike from the DA/SA would have saved the day.
