I have a few the DH3 version of the 320, I rarely clean them but I load my own with clean powder. Have over 25K through 2 separate pistols each and never fired without my finger depressing the trigger. Averaging 10K between cleanings. Quite a few people I shoot steel with use Sig 320 models and I have never witnessed one go off on their own it the steel bay or anywhere else. I shoot 2-4 days a week and see sigs almost every time. I will not be getting rid of mine.
Maybe it is mostly the cheap ones they turn out for the government contracts that have issues.
