I Found it best to leave the chamber empty, and release one to the carriage. This way if someone finds it and pulls the trigger it won't fire, and all you have to do if needed, is rack the slide and start shooting. Safe both ways.
It's been kinda crazy lately ... I've never had an issue with any of Todd's parts. It almost seems like the competition is out to cause him some headaches. I mean his latest video talked about someone complaining about stripped screws and we know for a fact he always checks those before he sends them out. Now this (above) and the complaints about paying in advance for backordering parts (which is SOP for everyone from Midway to SIG to you name it) ... I think Todd gets a bad rap on a lot of this recent stuff. Just my humble opinion.
The guy is a M4 affectionado.
I personally do not store long guns with one in the chamber. Pistols yes.
Here is one point of view.
