I guess I am a bit of a purist and can't acknowledge the new design as a 1911...I know that with all the different makes and models out there direct swapping won't work like the original intent of the 1911, but this takes it to too much of an extreme for my taste.
Can you accept the coned target barrels? Captured recoils spring assemblies? Solid guide rods? Multiple recoil springs? Or any of the couple of dozen other patents that are now commonly used on high end 1911 pistols but were designed by Detonics?
The sight attached to the barrel is actually not a new thing, its just be modernized by Detonics to this variant. In fact competition target shooters put sights on extended barrels long ago because the sight on the barrel doesn't move, but a sight on a slide does. So if you have a sight on your barrel then your eye doesn't have to try to watch a moving sight.
