Yes, I do trust the 320...it has not given me a reason not to. It has the voluntary upgrade as well, which was handled quickly and efficiently for me. Mine has been absolutely 100% flawless with better accuracy in my hands bone stock than the Gen 4 Glock 19 I used to have. Plus I don’t get the casings on top of my head like the 19 used to give me. As far as Sig’s ethics and in particular Mr. Cohen....I don’t know enough to comment on that. What I do know is that Mr. Glock has not been a perfect angel in his business and personal decisions and most big corporations could be accused of bad ethics at one point or another.
