I am borrowing this post from someone else on another forum. But it applies to my new MK IV Hunter.
The parade of Ruger Mark IV pistols heading back and forth from Ruger hasn't even died down and we find another "issue" with the newly introduced Ruger Mark IV. Oh Lord! What could that be?
The firing pins are breaking on a more than regular basis, and in many instances, the free moving firing pin tip is then, imprinting chamber mouth dings in the breech face. Seems some engineer had a "brain fart" that involved putting a #30 diameter lightening hole too close to where the radius where the firing pin stop pin and firing pin collide.
