Aaargh! I just saw it in print again. As stupid a concept as I have ever known. In a discussion on another forum about improving 1911 pistol accuracy upgrades, multiple posters allowed as how the OP’s gun probably shot better the he did. Where does this foolishness come from?
The accuracy of any gun is the sum of multiple factors; let’s call them errors. Two of the most important are the inherent mechanical accuracy of the gun as determined from a fixed rest and the errors by the shooter. So what if the group from the rest is 2.0 inches at 25 yards and the group offhand is 5.0 inches? Yes the gun is more accurate than the degree to which the shooter can operate it. I hate to tell you but this is true of every gun ever made. That’s what happens when you sum two positive numbers. The sum is greater than either one alone. The offhand number containing both mechanical and shooter error will be greater than the mechanical error alone. Duh!
So repeating something so obvious is silly. But worse yet, it gives a mistaken idea of what improvements can be made to the total accuracy. If you could reduce the mechanical error to a 1 inch group from a rest and the total group offhand to 4 inches instead of 5, wouldn’t that be a valuable improvement? I don’t know about you folks, but I would surely like to have that.
On the other hand working on shooter error is important too. Yes, there is even more room for improvement on the shooter side than the mechanical. But when someone is is properly interested in fixing all the sources of error in shooting a particular gun, it is just plain wrong to tell him the gun is fine; it is all his technique that is the problem. With very few exceptions that just isn’t so.
Shall we discuss?
