tl;dr, but god man thats old!! use the search. I figured that one out and did it for ****es and giggles the first time i ever took my tippy apart. I tried to shoot it with a revvy once, woulda made for one helluva nice margarita maker
edit: btw I did it in what is technically a better/simpler method. I simply cut a short length of heavy guage wire and stuck it inthe gap of the sear so that the sear is all the way fowards at all times.
