I just found this fine thread yesterday. I'd had to disassemble my 1903 because of a jam with a live round in the chamber. That's all taken care of safely! But I must be doing something wrong in reassembly. With the mainspring and grip safety installed with a thin slave pin, The long thin end of the mainspring extends higher than the hole for the slide safety. as a result it seems impossible to push the hammer down enough for the hole in it to line up at all with the holes in the frame. Or am I just a 90 pound weakling?!
