The video Mike7 is talking about is mine. My SR9 #1 when full auto several times after the recall and after 2 trips back to the factory. Also, continuing trigger reset failures. They finally issued me a new gun after I kindly provided the dvd video.
According to my detailed maintenance logs, I have fired 2050 rounds through SR9 #2. I have had 7 failures of the trigger to reset. Ruger sent me a new trigger bar reset and lift spring, and through the last 355 rounds the trigger has been resetting fine. I have had no barrel peening issues with either gun.
I love the feel and accuracy of the SR9, but trigger reset failures, combined with a 9lb 10oz trigger pull, have left this gun semi-retired.
I bought an M&P Pro 9mm for gun games, and could not be happier. My scores have gone way up using the Pro. I use my Kahr P9 or M&P 9c, both with CTC lasers, for carry.
