The sights Listed by Sgt Rock from Kahr will not work. The rear sight dove tail isn't even as wide as the top of the pistol notch. The front sight is too wide for it.

Not sure about the XS sights. I for one didn't like the design of them. Good idea, but I would be hesitant to change the "reflex" of what my sight picture would look if in a rush. Now, granted, the .380 would be best at a short distance and aiming wouldn't be a top priority.

Hopefully Smith and Wesson will come up with something on their own. Until then, I might be willing to try enamel or a phosphorescent paint.
