The malfunction was reported in `Concealed Carry Handguns’ 2012, Harris Outdoor Group #103, `Ruger LC9 9mm’, pp. 51-53, Dennis Adler.
I ran a couple mags of Hornady Critical Defense 115 FTX through mine with no problems. I may try some S&B next time.
I think I have a few boxes of S&B lying around.
I will have to give it a test.
