Lol press checks... The same guys that draw to their chest and extend then pull back into their chest before holstering. Meaningless. You should know if your gun is hot to start with, but even if you don't, like every single firearm made in the last 20 years has a loaded chamber indicator. Another point, if I don't trust my gun enough to know if it actually chambered a round when I closed the slide, I don't think I'd be carrying it... Maybe not even shooting it. I personally think it's a novice action, it probably won't jam a decent firearm, but cycling over a full magazine I would think could change the position of the second round.... Perhaps. Also, I've shot a lot of guns for a long time, I've never had one single instance of a gun failing to chamber a round without me instantly recognizing that it didn't chamber it.
