Well, the Henry company has done that with a number of .410 versions of their lever-action rifles. The Henry X in .410 stands as being of particular note because of the enlarged lever loop for use with gloves. My fortune with lever-actions has been on the low side, as I said in my discussion of the rifles TDF 23. But, that could be user error, and I can't deny the heritage aspect and the tactical merit of this weapon.
