Thanks to your video, you give me an idea to fix mine one. Basically just need to add some silicone oils to the outer barrel and internal of the slide and fixed. Cheer!

Lube doesnt help mine

Keeps happening to my gun I just bought

recommend mo parin ba yan na bilhin? balak ko po kaseng bumili at yan ang isa sa pinag pipilian ko

Gas pressure does not have anything to do with it. It's not rocket science. Had 2 of these guns and root cause of the problem is the slide catches on the edge of the outer barrel. Only solution would be to remove some material off the edge of the outer barrel.

where do you lube it to stop this from happening? do you lube the gun if so where? do you lube the magazine, if so where?

...you filled the magazine incorrectly. Too much continuous pressure of gas while filling caused your mag to freeze up and froze open your hammer strike valve when you fired your first shot and released all your gas, short 1 second bursts, 4 times and you should be good to go. Never press the valve button on the magazine to release gas or you will blow out the rubber seal which is where all that gas came from, but that’s only what I saw 🤙🏾🤙🏾🤙🏾
