Great looking old gun!
Travis, that may not be a Jones Underlever. Check to see whether the circle inside the gun has one or two locking lugs. If only one, that was an early gun and the lock-up is not as strong as you might want it, to be comfortable shooting the gun with appropriate ammo...Geo

Forget that, I see the double lugs in your pictures.
