I've put about 5000 rounds though my 320rx and have handled it pretty rough including a couple drops(unloaded, thankfully) and never had anything other than scuffs on the Romeo. Have it on my Shadow which also got dropped last range trip (not my fault that time, the stand in the shooting lane collapsed and the gun went with it, also unloaded) nothing to report so far for issues.
But yeah given Sig's quality control lately I'm sure there's some bad batches out there.
