I recently bought a taurus pt 111 and when i was reassembaling it, i believe the spring popped off and now i cant get the upper the set right and not only that i cant even detatch it no to find if that is tha cause.
I took my a part only one time. I was afraid of what happened to you. I was told you might have to send it back to Taurus. Check out you tube, you might find your answer there or take it to a gun store for help. I promise you're not the first person that has happened to.
