As you folks know so well, many of us with these new guns, Ruger SR9 and SR9c, have been plagued with light primer hits. Some of us have blamed the gun; some of us blamed the Winchester White Box ammo.
On May 13, I sent in to Winchester Div, Olin Corp, a selection of four light primer strikes (one-hit each) as well as four normally-fired cases, and ten fresh cartridges from the same box. I explained what problem some of us have been seeing with our new semiautos.
Winchester replied today. I have included pertinent portions of their letter.
"OUR EXAMINATION OF THE AMMUNITION RETURNED REVEALED A LIGHT FIRNG PIN STRIKE. THE AMMUNITION WAS DISASSEMBLED AND INSPECTED. WE FOUND THAT ALL OF THE COMPONENTS MET OUR MANUFACTURING SPECIIFICATIONS.
OUR INSPECTION OF THE FIRING PIN INDENT FOUND THAT IT DOES NOT MEET INDUSTRY SPECIFICATIONS AND WAS INSUFFICIENT TO DETONATE THE SHELL."
Their letter went on to suggest that my firearm should be checked.
In the interim, my SR9c has been to Service again. The Service department replaced the striker mechanism. In particular, the striker sping in my repaired firearm is longer, such that it now maintains a constant pressure on the striker. (I have a previous post concerning this repair)
I believe that Winchester (and Ruger Service) did an admirable job, and I sincerely thank both of these fine corporations for their interest in this matter.
