Thanks Ruggy. Mine is an early version, test shell casing dated August 2006...I also called S&W and confirmed same. Thanks again for the info and link to thread.
Traded a bunch of .223 ammo and an AR15 for a 460es. Kit is complete, gun is dated August 2006 (called S&W and test shell casings dated same). Knife has “First Production” marked on the blade. I’m assuming this is the original version of the kit. Is there a production quantity for this...
