We suggest reading our blog post with Q&A from Phil Strader. His response:
Q: What is “primer drag” and does it cause striker breakages?A: No. “Primer drag” is found on fired cases and is simply a drag mark slightly below the indent in the primer. It is caused by the pistol barrel unlocking while the striker is returning back to its recessed position. This is not uncommon, and happens in most striker-fired micro compact pistols due to the increased slide speed. The protrusion of the striker tip during ignition is minimal and has no effect on the striker’s durability.
In the event of a defect, Sig Sauer's warranty would cover this problem.
