I completely disassembled my Glock 19 Gen 6 MOS and after putting it back together, the trigger started sticking/getting hung up. I took it to a gun shop and they looked at it and said everything was okay, but I honestly don’t remember it doing this before I took it apart.
I’m not trying to mess with it any more until I figure out what’s going on. Has anyone had this happen after reassembly? What should I have the shop specifically check?
I can post a video of exactly what the trigger is doing if that would help. Just looking for some advice on what might be causing it and whether I should have another gunsmith look at it.
