Reliability issues are your answer Pete. Brass in a semi auto pistol needs to be fl sized to ensure it will feed properly.

Take a fired case and measure the body. Fl resize it, and measure again. It sould be a few thousandths of an inch smaller. This few .001's may seem miniscule, but it is actually very important for proper feeding.
