I'm pretty disappointed to post this, but I can't get my Ultra slug hunter to close up. The gun functioned perfectly, and has been fired hundreds of times. I had taken it apart, including the trigger assembly to clean it, and now it won't lock up. I have taken my trigger apart again, but still no go. I am not fighting the trigger in, but its not the easiest ever. I made a pin to hold the trigger and spacer together during assembly. Any tricks, maybe a spring I missed? All I see are the main hammer spring, the trigger spring, and the front spring which closes the locking lug.
