Yo Pirates - Ran across this thread at Bullseye's excellent site regarding the
Mark III, 22/45 pistolas. I called Ruger at 603/865-2442, left a voice mail and got a call back in less that a couple of hours - My replacement pin is on the way at NO CHARGE. They did need my serial number to verify the year of manufacture as the upgraded pin was used after June 2007 an is not an issue with the later models.
I urge all of you Mark III, 22/45 owners to check out this thread and take a close look at your pistola:
