Metal displaced around firing pin, cause for concern?

[The_Eric]

I'm sitting here cleaning my Canik TP9SF Elite after a little shooting and was cleaning/inspecting the breech face/firing pin hole when I noticed that the metal had been pushed out a bit around the firing pin hole.. Can sort of catch it with a pocket screw driver.

This gun has approx 3500 rounds of Winchester NATO through it (124grn loaded to 1200fps and at or near +p pressure) and has never once had any failures. Does this require attention/need repaired?

I would contact Cannik. most gun manufactures seem to take good care of their customers at least the ones I have had to use for issues. I have had Ruger, Smith & Wesson and Palmetto bend over backwards to insure I was pleased with their products

A couple more close ups of the pin

Yes, aside from any safety issue there is the issue of the shell sliding up the breech face when being striped from the mag. At this point it does not sound like a problem with ball ammo but you never know when it might be enough to catch the case rim and mess up the timing. You might also want to try pushing the firing pin through the breech and see if it is hitting or if the hole has gotten excessively large. If the hole is too large you could get a blown primer and gases blowing back through the firing pin hole, if its hitting it may cause a misfire at some point.
I just caught your follow up and it looks like the taper is hitting and pushing out the metal. So either the firing pin is just slightly oversized or the hole was drilled slightly under. Either way the burr needs to be removed and if given a choice always modify the cheaper part to fit the more expensive so polishing the firing pin to fit the hole would be my way.

A few angles of the fp protrusion

You don't want that ridge to grow, so flatten it. If it continues to grow, you can have a hardened bushing inserted by a pro gunsmith who specializes in doing that. There are quite a few online with good experience and references.
It's more common on rifles, I think. But it is pretty routine.

I think at a minimum, the slide and firing pin needs to be looked at, either by a gunsmith familiar with the pistol or sent back to the manufacturer for evaluation. But yes, it looks like routine inspection and correction.

I wouldn't panic, because it has caused no functioning issues. But yes, it should be looked at. That gun should be able to digest 3,500 rounds of NATO Ball with zero issues. Certainly without upsetting any breech metal.

I remember some years back Smith & Wesson had a similar problem with the firing pin hole cratering on their 686 .357 Magnum revolvers. They were tying up the guns in some cases with high pressure ammo, when the case set back against the breech face.

I have an early one, but it has never exhibited any such cratering, or issues. So I just kept running it. That was probably 3,000 rounds ago. The breech still looks like new.

I would at least check with them, and at the same time get an estimate on the turn around time if they want it back. Who knows, you might end up with a new gun.
