I bought a TX22 went to the range and shot it to confirm its function (it ran fine) and got home and disassembled it, while doing so the striker retaining pin went flying to Mars so I bought a replacement pin. But now the gun lost its proper function as it’s seems the sear is no longer catching the striker causing a dead pull. I’ve fully dissected the gun and no other parts are missing any ideas or help? Yes I know this is such a dumb fucking situation
