I have a green gas powered G19 airsoft gun. I am not sure of the actually model number. I believe it is made by WE and it is the gen 2 of the G19 but it doesn't line up with anything I've seen online. I tried to load 6mm into the mag but they did not fit through the feed hole thing. I asked on reddit and they said that it was just supposed to be tight. So I used a vise to force on in, which shaved plastic of the bb, then I have to use a screw driver to get it out. I found replacement magazine lips for the magazine. If I switched that out on my mag, would the gun funtion? Would it also work if I got another magazine that takes 6mm?
