I recently purchase an fnx40 and noticed slight bulging in the fired cases. Concerned about chamber support I dropped a round in the breech and found that the chamber is fairly loose. Measured it at .430 at the breech end. I'm wanting to do some serious reloading with 40 specifically with this gun but am concerned about safety. Is the fnx 40 any better than a glock in this respect? Should I trade her in on another caliber?
