Chipped Firing Pin

big_bang · August 17, 2008, 08:30 AM

I've got a S&W 610-3 (floating frame-mounted firing pin).

It fires .40S&W at 100% (small pistol primers), but will not fire a single 10mm (large primers). The strikes on all primers look funny, like the pin tip may have chipped - it's not a neat concave bowl, but rather a ring with a very small convex portion in the center, and it's not perfectly concentric. When looking at the pin silhouette from the side while in lockup, it looks flat at the tip.

I guess I'm off to find a shop manual and a firing pin. Any suggestions on which manual and sources for both? Brownells only has parts listed for a -2. I'll probably get a mainspring while I'm at it just in case...

Might chat it up with the fine folks at S&W service?

That is an option I am retaining. I have performed work on other firearms, and am mechanically competent. This would simply be my first venture into a double-action Smith. I'd like to learn my machine.

My only real issues at this point are
1) recommended manual
2) Parts source for a -3 (outside the factory option)
