Aimco Luger Failure to reset trigger

[1SGGetch]

Hey Folks,

Picked up an Aimco Luger and took it to the range today but ran into an issue. After loading and firing the first round, the weapon had a "dead" trigger and the only way it would fire was to cycle the action and then it would fire the third round of seven. At no time did it fire two shots in a row.
I took the weapon back to the bench and started comparing to my G-Date, of course, none of the parts are interchangeable so I couldn't change side-plates to see of that was it. So, in messing around with a lot of stuff I cycled the weapon with snap caps trying various things to get it to fire after the first cycle. I discovered that if I push the trigger slightly right to left I can hear a small click and the weapon resets. It wont reset pushing it forward and the trigger spring returns the trigger properly. Every time I push the trigger sideways left it resets the transfer bar.
Not being a gunsmith but having worked on everything from 9mm to 120mm I have a bit of skill but not a lot of courage with a pistol you cant get parts for.
Do any of our esteemed knowledgeable luger folks knw a fix for this?
