Thank you for posting the article. Like any published article the author has to come up with parameters of how to run the test/evaluation. And then the readers have an endless list of.. "well... he shoulda done it this way". I suppose if they did it exactly the way we wanted we'd come up with different complaints. But I will take exception to using using one kind of ammo for each gun. That instantly makes the results invalid save but for a single kind of ammo. It leaves the reader with the impression the Ruger 10mm has a ftf problem. But with only a single ammo type used the reader is left with no idea if the Ruger actually has a problem or if it was only with one kind of ammo. In any case, I would 100% flunk any gun that did not run 100% with the intended carry ammo.
