I can see the left-hand bolt being extremely important and a real deciding factor if you're left handed! As well, is the 'switch' you're referring to the safety switch, or another switch (receiver toggle)? This is why I ask before I buy, since more and more people might start bringing up common problems with the weapon systems and thus prove to be a deal-breaker. I do also like the extra metal in the TAR, since the weights of the weapons are very close, and moving plastic pieces do scare me somewhat.
The "switch" is a white plastic part attached to the bolt. I think its function is to make the brass eject to the front. It is not a safety switch. It provides critical function. Some forum site suggests that the switch is not easily broken when shooting, but only when disassembling /assembling, since it uses a hard spring to lock it in place.
