A chambered round is not a TSA rule

So you want him fooling around with it even more and thereby INCREASING the likely hood of an ND?

Ahem...A ROUND SHOULDN’T HAVE BEEN CHAMBERED IN THE FIRST PLACE. Sorry for shouting, but the point is pilot error occurred when he chambered a round, not when he activiated the the trigger lock (bad though the design certainly is).
