When the gun chambers the fourth round, it chambers the fifht round at the same time making one of them roling out of the barrel by pushing one each other. Whatta?? Is it the mag or the thing that pushes the bullets in to the hopupchamber?? The slide didnt fully engage a couple of times and i thought maybe the gun was dirty and needed to be lubricated. So i just took apart and cleaned my gun and ill shoot more tomorrow. Anyone have any idea why my Glock shoots double shots? It shoots 2 at a time and the 4:rth BB of 5 in the mag roles out IF i load it with 5 rounds et.c..its always the one before the last round that roles out..kinda stupid. Seems nothing wrong inside really, nothing wrong with my mags, nothing wrong with the gas, its all just a mystery. Its quite sad that ive paid alot of money fo it to. I just bought very new like 2 weeks ago. Can someone here figure out whats wrong and help me, maybe i can repair it on my own?
