Is the hammer spring installed correctly? one of the real long wires coming off of the hammer spring is what holds the trigger pin in position, the long wire fits down in the groove on the trigger pin to retain it in position.

The trigger pin should not be a roll pin, it is a solid pin with a couple grooves cut in it.

On the rare occasion I had to deal with PSA customer service, I had no complaints. I called them on the telephone though.
