9mm miss fires
this is a follow up to my first post. sig 226 still not fireing using winchester primers but when you pull the trigger on the same round till it fires we are getting different hits on the primer with the firing pin( three triger pulls to fire round and three different hits on the primer side by side) what could be causing this and what do I need to fix it.

Disclaimer: I am NOT a gunsmith and only a "shade tree" re-loader but it seems to me that my first suspension would be the primers. If your 100% certian that you used the correct pistol primers AND the rounds from the same batch worked in other pistols, your left with the firing pin/spring issue, as you suggest. MHO would be the gun needs to be gone over.

Re: 9mm miss fires
My first thought was that the area of the firing pin channel in the slide where the firing pin spring is, needs cleaning out. The firing pin and channel, spring, safety lock and spring, and extractor has to be oil and grease free. It needs to be dry in there so as to not attract dust and lint and clog up the area where the firing pin spring is. If the very first shot of the day misfires, there is oil around the firing pin spring and usually the second strike will fire the round. The slide can be taken apart and cleaned or squirt some carburetor cleaner through the opening in the breech for the firing pin until it comes out the back clear.
Sounds to me like the P226’s need a good check up. If the mainsprings were changed out with weaker springs how would anyone know? Many things could cause the problem you are having. I would buy some WWB from Wally World and see if it works in a couple of those P226’s. Then we could narrow the trouble down to the pistols. (Winchester White Box USA9MMVP, Walmart, 100 rounds to the box, $25.00)
As far as the reloads go the primers could be hard or not seated all the way down. You probably have already checked this though.
