Thank You for making this video . . . I purchased a spurred hammer for my Model 908 and because of your video, I was able to disassemble my gun, change the hammer, reinstall everything and it worked! I had to shorten the hammer spring stirrup by about a half-inch (I matched it up with the original hammer and used my Dremel to cut it down). Great video and everything was well explained. Saved me about $60 by doing it myself.
