    I don't know anything about these, but in the 5th picture you have, the firing pin safety appears to be in the slide farther than it should be....is the extractor installed correctly?

    Good eye PP!

    The hump on the bar for the poly 80 is IMO notoriously too high compared to a genuine Glock. I saw it on mine as well as other friends. To illustrate one being excessively high, I have taken a sharpie and colored in the area to The front of the plunger on the slide then slid the slide back and forth while pulling the trigger and the hump rubs and wipes out the marking. On one of my friends you could see the slide cant counterclockwise as he started to pull the trigger. Had to file it down. Again, if all was good when running the slide without the plunger in, it was fine.
    Also when doing a trigger reset test (hold trigger down as you pull back slide and release slide) you could see I slide struggle returning back and sometimes stalling just as the barrel was popping up.

    Has to file hump down then get the original shape and then buff with sand paper and flitz to polish

    This is one of the main reasons I fill my P80s with OEM Glock internals.

    So, I looked through my pics of when I was fitting a poly 80 and the point where the hump hits the plunger is much further in than the OP is experiencing a problem.

    But to show what I am talking about here are pictures showing the rub you get on a slide by the hump being too high.

    I put the drill jug across the front and rear blocks to show how high it is before filing compared to a stock G17

    Then to test after filing, use sharpie . To verify. Keep trigger pressed and repeat to make sure it’s not scraping. But don’t take off too much or it won’t depress the plunger and your pistol won’t fire
