Will Kane 35 Posted April 22 Share Posted April 22 The left firing pin nut on my trusty 1878 came loose and I'm trying to figure out the proper size nut driver to get in order to secure it. The parts manual I found online does not specify. Can anyone educate me? Please and thank you. Quote Link to post Share on other sites
Garrison Joe, SASS #60708 2,995 Posted April 22 Share Posted April 22 (edited) Chinese, huh. Chinese firing pin retainer nut is tapered, so I find a "slit" nut driver socket fits better than most. I took a 9/32" nut driver socket, ground down the outside to get it into the boss around the nut, and with a hacksaw sliced down about halfway into the socket, putting the cut on the nut opposing "corners." This gives me a socket that better fits the tapered nut, and is self adjusting. In metric, an 8 mm socket, IIRC. Has worked for me for 15 years now. good luck, GJ Edited April 22 by Garrison Joe, SASS #60708 Quote Link to post Share on other sites
