I'm curious... I have two M&P-10's and neither sport
the iconic M&P 10 etching on the side. Instead simply the
S&W logo.

This is not a complaint, per say, as I love the rifle and actually
like it better without that etching.

If I recall correctly both rifles were produced late in 2022.

But when did they start (or stop) doing the M&P etching?
