Off center firing pin

This story is too good for me to just bury it in the Other Handguns section (as a continuation of an old thread of mine). So about a month and a half ago I got a great deal on a used Ruger P95 9mm. It was barely used looks like only one box of ammo had been shot through at all if that. I owned two of them previously so I knew what I was getting into, P95's are supposed to be super reliable war horses, if you can't kill em with the bullets you can pistol whip your enemy to death with one. So I took it to the range three times, first time 90 rounds went great, second time 90 rounds had some failure to feed/eject issues that was likely caused by me forgetting to lube the pistol before shooting (a rookie mistake, it was still in the break-in phase). But the third time....

So I took it to the range again about a week ago. This time I was shooting plain Winchester White Box 115gn FMJ. And then it happened right from the first shot, the gun started misfiring about every third or fourth round. Out of 90 rounds I'd say maybe 12 or 14 did not fire on the first try (they all went bang on the second shot double action). I could not figure out why the Ruger suddenly was giving me such weird problems, so I researched. I got all kinds of theories, but when I examined the spent brass I got a better clue. All the shots had the firing pin indents off-center on the primers. So I decided to take a look at the breech face of the pistol. After nearly 300 rounds the brass had rubbed in the usual circle of the rims and primers on the breech face and sure enough I could see the firing pin hole was OFF CENTER. Yep, someone in the factory drilled the firing pin hole off center in the slide, I guess that means I will need a new slide. I haven't called Ruger yet, I don't even know if they can replace it as they stopped making the P95 in 2013. I'm not the original owner so I don't know if this is covered under warranty, guess I'll have to call to find out. Weird thing is though it shot fine with all other ammo up until now and only problems just with the Winchester stuff.
