[Hectic]

I cant see your pics of what happens. If i had to randomly guess id say valve knocker/striker andba good cleaning/lubing wouod bebthe first place to start.
When you try n shoot it does anything happen. Is gas released. Does the slide move. Does all the gas just vent. Is the slide going back the stopping?
Perhaps load a video. Or check a local gundoc. Id bet someone would take a look for free and give you a cost to fix it. If parts are available. I know it takes the standard tm/kj type hammer spring and such so hopefully the rest of the internals are the same.
