Thanks for the input everyone. For starters I'll give one of the paint/nail polish techniques a try. I also like the suggestion of using the "whole gun" as the sight - pretty much like point shooting a rifle, you get so you dont really (at least not conciously) see the sights but just the overall relation of the gun to the target. I think this is most practical for very close work with a handgun as it is quite difficult with a handgun, more so with a snubby. Seems to me most defensive shooting instructors stress front sight acquisition in any shooting scenario anyway though, so I'd like to improve my sight's visibility. Lasers are an excellent option too, but I've never been a big fan of them. If night sights are an option that would be the best IMHO, but there's not alot of metal to work with to install them, either in the existing blade, or some sort of dovetail or pin arrangement.

Great info and suggestions, lots to think about.
