I've never seen but one older defective B92, and I suspected that Bubba had messed with it. I have seen 3 Tennessee factory pistols that looked like crap. One had a sticking trigger. My comment stating fear about QC is an opinion based on insight into the industry over 50+ years. The last M9 from the government contract was shipped in Sept, 2021. The Tennessee facility began operating 2014-2015 and had the usual kinks seen in new factories. These kinks manifested themselves in a lower degree of QC. New folks operating and maintaining equipment and the same performing assembly and finishing tasks produced a couple lemons. Bean counters now can get away with more cost cutting. Uncle is no longer looking over Beretta's shoulder. Things change. Hence I fear that the once stellar product might slip or fall down. I have no idea about different lines of manufacture.
