The Glock fails to shoot about once out of every 5,000 trigger pulls, but that is more often than a revolver. Lets look at the other form of reliability. In a study of NYC police, almost two thirds of the time they shot at someone from less than 6 feet away, they missed completely. That is the most important unreliability in handgun use.
So you get off two bullet with your revolver, each which has a one third chance of hitting anything. The other guy gets off ten bullets, with the same chance. You have a 56% chance of hitting anything, and the other guy has a 98% chance. I guess under alt right math, 56% is more reliable than 98%.
