I kind of felt like the cloth of his glove was sticking into the trigger guard more than his finger was. But then again, his finger should have been held straight, above the guard and against the frame.

In my personal experience, I find that when it's cold and people are wearing thick gloves, they tend jam their gloved finger in the trigger guard and leave it there. I got into a fight with my brother once because he kept doing crap like that.
