Wouldn't snap caps add more wear not less?
Most snap caps have a spring mechanism in the center of the snap cap to cushion the blow to the firing pin tip. Without a snap cap the firing pin edge (rather than tip) hits something full force behind the breech face. That could be a pin or something else and depending on the design of the pistol some damage could occur over time. I would rather have a device to cushion the tip of the firing pin rather than wondering if any damage is being done where I can not normally see. It is well known that CZ 75 pistols can suffer damage from dry fire. It is only a replaceable pin but still and enough damage to the pin would cause pistol to fail. Some generations of Glocks have been know to have the breech face destroyed from behind by extensive dry firing.Wouldn't snap caps add more wear not less?
