Firing pin creating sheared divot on primer.

Hey guys. I have a Springfield XDM2 .40. I was shooting the other day and noticed this happening. Any ideas on why or how to fix this?

That's common on short barreled sub compact pistols it's due to the timing and short cycling of the slide. Sig P365's do the same thing.

It's fairly common in many pistols, but that doesn't mean it's a good thing.

It's often referred to as "firing pin wipe", and it can stress the tip of the firing pin or striker enough to cause problems over time. Keep an eye on it, and if it gets worse, or you see any evidence that the tip is broken or chipped, have a gunsmith inspect the pistol, or send it back to the factor for a checkup.

It may go on like that for 20-30 years or more, so it's not an OMG-it's-gonna-break-soon thing.
