The pin that holds the trigger in place, has become real loose < I've got two custom pins with buttons on the end , so no tool is needed to remove them How can you make them feel tighter, so they won't fall out ?
They were made for easy removal without tools so I would expect them to be loose. How do they compare to the factory pins? Isn't there a groove on each side of the pin for a wire spring to hold the pin in place maybe those are worn out. Don't own a 391 anymore so I can't look.
A. Put a piece of duct tape over the pin heads. B. Go back to the stock pins that don't fall out. C. Ask the genius who made your custom pins. D. Super glue. E. Drill the holes in the receiver smaller. F. Get a new gun. ( I like this one....)
