Good sights, one issue - AmeriGlo Cap Glock Rear Night Sights

These sights are awesome. Very easy to pick up and make fast hits with. I do, however, wish the tritium vile was a little wider. It sounded good at the time to have a slightly smaller front post, but the dot with no charge to the photo-luminescent paint is a little hard to see. Will a full charge or in decent light, everything is great. It's just that almost total darkness situation that concerns me a little. I don't find myself in dangerous places in total darkness often, but it would make me feel better just the same if it were bigger/brighter.
