Hi. Trying to find out info on this - searched but no joy... Had a look at job and seems like you'd have to take out the trigger return spring to do - correct? No gun shop local to me (I'm Thailand) so looks like I'll have to do myself. Do you need a special tool to refit spring and its pin? (Yes, I'd like to order from Cajun and get that pin sleeve thing to help - but as not US, no can do.) I can deal with a bit of awkward but sometimes such things can be super difficult without the right tools... Anyone done or know of vids/instructions? Cheers.
