Probably way more than enough. In a gang of 100 no one wants to be the first one shot, or even the tenth one shot.
Many years ago, I was returning from a hike. When I got to my car, which was still miles from the nearest paved road, there were 8 guys sitting on it, drinking whiskey. They got off and started to surround me.
All I had was a 6 shot 22, which I pulled. Happily, none of them said, “8-6=2, we can take him!” In fact, I was able to get in my car and drive off without a shot fired.
Of course, those 8 were not Amish, so it might go down differently now.
