I recently purchased one & upon a closer inspection I noticed a notch on the breechface right where the firing pin lines up. I assume it's from dry firing but was wondering if it could be done at the factory. It seems to fire & function fine & I can't tell that the peening protrudes into the chamber. Just wondering if it was "normal" or needed a smith to correct it.
Sorry for the poor quality pics. Cell phone camera is all I have.
