Does not fire - Apex Tactical Specialties Glock Gen 3-4 Action Enhancement Kit

The connector that was included in the kit looked different than the one pictured. My pistol would not fire. I had to disassemble the slide by removing the backing plate multiple times as I could not remove the slide without firing the pistol. I replaced the connector with a stock polished connector and it works fine. The trigger kit feels great now. Nice wall and crisp reset. I ordered a different connector from another manufacturer. Maybe this kit was purchased and returned with the wrong connector before I received it.
