I've been told that there's still an element within the company that would like to see exposed-hammer revolvers offered without the ILS. As long as corporate decides to take the advice of their legal dept, though, it's probably not something going to happen any time soon.
Also, as long as the ILS-equipped revolvers
continue to sell well, it's not like they're losing market share of revolver sales. The customer demographic who might be said to comprise the 'traditionalist' element is aging and being replaced by younger buyers who may not care about the aesthetics of the ILS.
The 'traditionalist' demographic is cheerfully inflating the pricing of the remaining older revolvers, too. The world goes 'round.
