I bought a used one that the owner guarenteed to shoot Gold Dots and Hyda-Shoks. I have never had a failure of any kind with it. 115 and 124 gr GD, two kinds of Federal 124 gr, Hornady 115 gr Critical Defense, and a 124 gr Gold Dot equivalent reload that I use for practice in the R9 and my PM9. All have functioned perfect with about 200 rounds.
Good luck with yours.
