Seems like it would be fun to dink around with but I don't get the pistol cartridge in a lever gun concept.
The plain old .30-30 covers that ground, and more.
Thankfully, the 30-30 will never go away. But, I'm liking the concept of pistol cartridges in a lever action. Very traditional and the anti gunners seem to be leaving them alone. I realize the S&W may not be everyone's first choice but a lever action has been re-gaining that "cool factor" it had 100 years ago. I see no downside.
