I've put over 2000 rounds through my P226 9mm. I can remember 2 failures. 1) A failure to eject that was probably due to a light load or a limp wrist. This was with the 1st box of ammo I shot. 2) A failure to feed which was due to a damaged cartridge. I do take good care of my guns. With rental, you have no idea ... may be dirty, insufficient lube, weak springs, etc.
