I have little experience with bright-colored sights, but I have had occasion to shoot the same model piece with blackened sights and with stainless, and I found the stainless much harder to use in many lighting conditions. <br><br>I have the impression, possibly incorrect, that the bright sights work much better on an open, sunny range against a black bulls-eye on a target.<br><br>I'm personally not crazy about tritium sights- they are expensive, and they lose about half their brightness in five years or so. Five years is not a long time for that kind of money.<br><br>If the M6 front sight is stainless, I'd advise temporarily blackening it with candle soot or something else easily removable and see how that works out for you. In low light conditions you may be surprised that it's more visible than bright colors.
