340 sc vs 340 pd.

[Cal44]

What is the difference between a 340 SC and a 340 PD?

They seem pretty much the same at first glance.

They are the same except for color and I think front sight. Also, not sure about the SC but the PD is available without the lock.

Yep, no lock on one of the M&P340. I have one its great.
The PD is a little lighter if I remember right but does have the same front sight.
