Pawpaw, no argument from me and I personally have no experience with Sig firearms. The author's gun has FTF problems with no indentation on the primer. When he sent it back they cleaned the firing pin channel and apparently it worked for awhile. For an unfired cartridge to have no indentation on the primer there has to be either an exceptionally hard primer or for whatever reason the firing pin is not hitting the primer to fire the cartridge. Why this is happening I do not know. Since the ammo used did not show a primer strike on the unfired cartridge I would assume it's the firearm at fault.

This is not the first time I've heard this, but it makes no sense. How could "primer material" get into the channel unless the primer is being pierced, allowing material to blow back into the channel. If that's happening, how is that the pistol's fault? That would be an ammo problem, not the gun's fault.

I call "BULL" on that statement. Not at you, but whoever originally wrote that nonsense.

I don't want to quote the whole article but they said that with Cor-Bon ammo...definitely weird.

"Waiting for the second gun, we closely examined the breech face of the first one. There, we finally found the real problem. The firing-pin hole on the breech face was blocked by a plug of primer material that had been scraped off the bulging fired primer of the Cor-Bon ammo. This little plug was jammed into the firing-pin hole. It spread the force of the firing-pin strike, which didn’t even dent the primer. This, too, was a first for us. Recovered Cor-Bon cases fired in the P938 had their primers blown completely flat. They showed no trace of the firing-pin dent, but they each had a scrape across their face. The scraping action had cut off the protruding primer metal and jammed it into the breech face hole, and that blocked the firing pin."

Wonder if something similar is happening here as author did have "no strike" on some primers. Something is strange when FTF and there is no mark on the primer. Not even a tiny indent. I am only relating the article as I have never even held a Sig.

Gun-tests, Mar 2013 tested this gun and had many similar problems that you described. They gave it a "D" grade. They found a broken extractor and primer material blocking the firing pin hole on the breech face. Their problems with the no primer strike were with Cor-Bons ammo. FYI. GunTests is well worth subscribing to.

Call Sig. You don't want any alterations done if you have to send it back. When you had the first failure to even leave a mark on the primer I would have been calling Sig.
