Wow, that does indeed look rough, I’ve never seen one that bad, glad Dave came to the rescueA big thanks to Mr Dave for sending me various parts to sort out the problem. It appears that the pin was faulty, very rough compared to one Dave sent me. It is obvious that the pin was grinding against the rubber and that’s what was rendering trigger action slow. Once replaced with Dave’s one, the trigger is smooth and feels great.
You can see in the attached image that Dave’s pin (top) is shinier compared to the one came preinstalled in the AB (below).
Again, thank you Dave.
