Yeah, bad lots sneak through from time to time. I have to suspect that with the incredibly high demand right now they have production running as fast as possible and hoping to catch anything wrong in final inspection.... Which sometimes doesn't............. Once people report issues with stuff they bought then the rush starts to determine what lots were involved and get them returned before guns are damaged and someone maybe gets hurt. I've seen a number of these recalls over the years, happens even during normal times. And these are not normal times or normal demand right now
