I bought my Glock 17 Gen 4 about 3 months ago and put a few hundred rounds through it with no problems. I installed a Ghost 3.5 connector along with all brand new springs. I put another 100 rounds through it without any issues. But then after those first 100 rounds I have been getting several misfires. On two separate occasions with three different types of ammo I have been having close to ten misfires per 100 rounds. What could be the issue here? Should I go back and swap out any particular spring that I changed with the Ghost connector or should I change them all? I have disassembled and cleaned it twice since making the conversion so I don't think it is dirty. Any feedback is greatly appreciated! Wanna kill these ads? We can help!
