Luv2rideWV Posted June 13, 2014 Share Posted June 13, 2014 On some of the old S&W revolvers I've owned, the hammer mounted firing pin seemed to flop up and down a bit. Guns that did this were well worn model 10's and 15's. The guns worked fine. Was that normal? Would that have ever caused any problems? Worth fixing? I just wanted to know.

Toolguy Posted June 13, 2014 Share Posted June 13, 2014 On the older ones the firing pin was floppy because it had to pivot as it entered the firing pin bushing. Occasionally, it would be in the up position as it entered the frame, catch on the frame at the top and break off. They did 3 things to remedy this. On some models they filed a notch at the top of the slot for the hammer for clearance. Later they shortened the firing pin (1988) and put a spring behind it to hold it in the down position until it got to the firing pin bushing. The actual name for these parts is Hammer Nose and Hammer Nose Bushing. Now you know The Rest of the Story. Link to comment Share on other sites More sharing options...
Luv2rideWV Posted June 13, 2014 Author Share Posted June 13, 2014 Thank you Warren, that does explain a lot. The 1990's vintage 686 and 65 seemed to have some spring tension on the hammer nose, and that made me think something on the old guns were broken or worn out.

Bosshoss Posted June 14, 2014 Share Posted June 14, 2014 These firing pins are no longer produced by S&W and are getting hard to find and expensive. Just got some in From Ron Powers. He is making them and they are supposed to be stronger than stock and they come with a Rivet and spring. He make them for K,L, and N frame. Brownell's has them. http://www.brownells.com/handgun-parts/trigger-group-parts/hammer-parts/hammer-blocks/hammer-nose-kit-for-s-w-n-frame-sku713000169-60393-126186.aspx?sku=713-000-169 Link to comment Share on other sites More sharing options...

Don't try to change it. Link to comment Share on other sites More sharing options...
