I her ya, Fabs. When I worked in the gun store, I did scores of trigger and sear replacements on the 10/22 - with either Power Custom or Volquartsen replacements. Firing pins, too. Could probably do it now on muscle memory alone!

No matter if your labors succeed or not, I'll stand by the replacement firing pin suggestion I made. The Volq titanium pin (is titanium nitride coated, too) really makes a difference.

Rocky,

I have tried to find the Volquartsen firing pin a couple of times, and nothing comes up on their website for a firing pin, unless you are talking about the CNC machined bolt that has a firing pin already in it. That bolt and firing pin are different from what the stock bolt looks like. You probably already know that the stock firing pin is barely held into the bolt with a pin and two tiny indentations in the bolt. I'll check Power Customs website to see if they have any firing pins.
