I have a PX4 purchased used. Was is very good condition and no visible issues. Put around 700 rounds down range since obtaining it.
The last trip to the range after every round the slide would stick to the rear past even where the slide lock would engage. Had to tap it to get it back in battery, after about 5 rounds it was clear something was wrong.
I was also able to duplicate that condition by hand with no magazine and no ammo in chamber.
I removed the barrel and placed the recoil spring in the frame and put the slide on. Cycles fine to rear and does not show any signs of binding. Once the barrel is installed is when this condition happens consistently.
I have to assume something worked it way in there and caused this issue? Not sure what to do right now except take it out of my EDC until figured out.
Some images taken last night.. does anyone see what might confirm excessive wear? I honestly haven’t closely inspected the barrel previously that I can say yes or no.
The image of the barrel attach#98183 seems to show possible gouge in the groove?
