The answer is easy IMO. Michpatriot said it all. Send it to Williams. They will have you running 100 in no time. They will also pay for the round trip shipping in my experience. Talk to Alex (or Alec. Not sure).
This is why I have a spare R9.
Also, get while the getting is good.
This is also why I finally succumbed to the wisdom of backup 9 and others.
Carry always. But only shoot a little. It won't go bad sitting in your pocket (thanks ECR) and just run 2 mags (then clean and repocket) every once in a while at the range to give you proficiency and confidence in your weapon. This is what I have finally adopted after getting my R9 100.
If you think about it, it doesn't really take TONS of skill to deploy and empty a mag at 3-7 feet.
Also, a lot of these skills can be honed at home with a dummy round and dry fire if you so desire.
You may be hard headed like I am, but I finally came around.
I use the Glocks and sigs to pound the paper and steel at the range. The R9 gets special treatment and I have a backup since being without mine for a year almost was a real drag before Williams began their warranty service.
Just the random thoughts of an X- R9 abuser. Lol
