So i just got a kwa (ksc whatever you want to call it) g17. got it from a friend who got it brand new in cali. Loving glocks i got my hands on it, know it had a problem. But I've never ran into this problem with other glocks I've owned (All ksc/kwa.) Here is the problem: Put the mag in, cock it, it shoots semi 1 or two shots, then goes into bursts for about 2 trigger pulls. then just shoot out all the gas. I'm guessing it is a hammer problem.. That it is hitting the gas release and staying there maybe? I'm just not entirely sure what is wrong and how to fix it, Hope someone can help! Thanks!
