This is one more comment about the IL hole and the appearance aesthetics ( beauty ) of revolvers in general. Once you admit that the IL empty hole is not going to be a functional problem for your gun, it's about the looks.
The IL hole doesn't really do anything detrimental to the looks but what's in our heads. It's just one more hole in the gun. Well, let's admit that revolvers have a beauty to us that is borne of the "form follows function" attitude. Actually, they are not so good looking, as pure art goes. The reason we like the looks is that they are functionally so well developed. Other connotations are the potential power, the implied threat, the craftsmanship or precision, the design solution, the history, etc.
