Striker marks on primer

[boatmanschneider]

This is the used brass from my wife's new SR40c. Should I be worried about wear/damage to the striker. Is this normal for this Ruger?

Looks like the primer is dragging on the firing pin during extraction.
A lighter firing pin should fix it, I'm not familiar with striker-fired guns though.
I wouldn't lose any sleep over it unless it's causing reliability issues.
Excess damage? I wouldn't worry, firing pins are pretty strong as the metal in a primer is pretty soft.

I guess I am failing to see anything wrong in the photos. Looks like the spent brass from my Taurus PT-145.

What you're seeing is called primer wipe. It's perfectly normal on a lot of guns, but I don't know how the SR40c is set up. I wouldn't worry about it unless it starts gouging the edge of the primer pocket.

This is a common problem. The cause is a weak spring. The fix is to replace it with an extra power spring. If left this way the tip of the striker/firing pin can be snapped off rendering the gun possibly jammed and unable to fire. It is a classic case of Yin and Yang. Enough force has to be applied to the hammer/striker to strike a primer hard enough to light it off. At the same time an equal and opposite force has to snap the pin back fast enough before the barrel unlinks and drops. Most "experts" will tell you ignore/not worry about it but I have seen broken pins in guns when this is ignored depending on how hard and how brittle the pin/striker steel was. Many manufacturers buy springs in huge quantities and the quality and tempering is not always as it should be. Check with ISMI or Wolff to see if they offer replacements. Otherwise you'll just have to go to Ruger and hope you get a better one. At the very least call Ruger and ask them if they believe this is a potential problem.

Ruger said it is normal for all striker fired guns. Don't worry about it.
