New Hellcat RDP - Pinhole in the Barrel?

Well, obviously you've already gotten your answer, but yes, mine does have the little mark. I saw it myself and didn't have to even disturb the little lady ...... much less wake her up.

Very cool, who knew?

But,

It is not a hole really, doesn't go all the way through, more like a pit mark.

Just saw the post where someone said this is a mark from where they tested the hardness?

Will see if customer service confirms this.

I checked mine with a really bright light this evening and XDMAN is correct. It clearly doesn't go all the way through and looks like a punch mark actually without the raised outer edge.

Yes,

The Springfield rep I emailed never said exactly that it was from a hardness test, but that it is a mark made as part of their manufacturing process, and that some barrels may even have 2 marks.

Good article and explanation xdman, thanks!
To me, if looking closely, the mark shown in this thread basically appears like a punch mark prior to drilling metal. Essentially is what the testing does by dimpling the metal to specific guidelines.
