They're gonna sell like crazy at above retail prices unless you get an order in at MSRP or less from your dealer. Looked them up- about .2" narrower, .25" less in height and .8" shorter in length than my G36 and Kimber RCP.
Still too big for pocket carry and wonder what kind of velocity a 3" 9mm will produce.
Looked at the LC9 today at SHOT. I would compare it to the size of the Bersa 380s.(no side by side, but just a general comparison). A good bit bigger than the Kahr PM9s. I really did not care for the looks of the chamber loaded indicator on top of the slide.
