Did a bit of research since yesterday and came up with good reviews on Williams Firesights and Meprolight tritum sights. The Williams sights look good but I worry about the fiber optics being fragile. The Meprolight are more expensive but there's nothing to break, plus they are true night sights. Only downside to the Meprolight is a lot of customers complained about having to file the front sight to get it to fit. Seems like a company would listen to the reviews on their product and make adjustments at the factory. I could file them like most other folks but shouldn't have to with a $125.00 set of sights. I can own the Williams for less than $50.00. Decisions, decisions. Back in the day, Millett white outline rear sights were the thing, I can't even find them now.
