i just bought glock 22c 40cal and when i test fired it this weekend it always jams within 10th to 15th rounds. I used armscor FMJ and i fired 100 rounds. I never had a complete 1 magazine (15 rounds) fire without jamming. This is disappointing to me considering that it is my first gun. WHY IS THIS SO? WHAT DO YOU THINK WENT WRONG? WHAT SHALL I DO ABOUT IT? Moreover BOGS, what part of the gun shall i grease/oil? wala kasi sa maual instruction gun cleaning eh. Wanna kill these ads? We can help!
