Do you think most firearms failures are gun, operator, or ammo related? I have found that about 90% (just estimating) of all gun failure I have seen are not actually the fault of the gun but more often the fault of the ammo or operator. Ammo is usually the cause but in second place would be operator error. I have seen very few cases where the firearm is the actual issue. I have seen so many people bring a gun into the dealer wanting it sent back for one reason or another where I have stood there and thought to myself..."that is an ammo issue" or "that is because you do not know how to operate, or are incapable of operating, the firearm." I think cheap ammo and improperly self-loaded ammo is the biggest gun failure cause. There are of course gun failures. I had a new Colt 1911 seize up completely the first day it was taken to the range. It was a complete lemon. Usually though the fault is either mine or the cheap ammo I am shooting. I also think most gun failures that are do to manufacturing defects are usually minor parts.
