Can anyone help? I purchased an aluminum trigger from Cylinder & Slide for my Colt Mustang Pocketlite. I would like to replace it myself but I am unable to remove the pin holding the stock trigger in place.I hesitate to use too much force for fear of damaging the aluminum frame. Does anyone know if this is only held in place by friction and if it must be removed only in one direction. Also, is there any special way to remove the trigger assembly? Does anyone have any experience in this area? Your help is greatly appreciated.
