I've owned/own several from base, legion, X models, personal builds, etc... since the platform was introduced with zero issues whatsoever. I've not bothered to maintain a combined round count, but it's substantial to say the least... Full disclosure, a couple i babied but I've ran most like Harleys on a rough piece of road. I know many shooters who also own various weapons from this series and none have commented to any safety or function issues. Some complaints to "feel" or preference, as we all have had with weapons that just "weren't my cup of tea."
I'm not a Sig fan fanboy, though I do prefer them over some weapons... again, it's a preference thing. I will say all the negative press was initially disconcerting. But, given the numbers of these weapons in circulation compared to relatively few instances... many of which being questionable... You're an adult and you can sort out where your opinion falls. Personally, I will continue to shoot and carry the 320 variants as part of my EDC and range rotation.
