Trooper - there's a better/cheaper/easier solution to your problem if you're willing to invest a little labour in the solution.
Here's how...
Use alcohol to clean all oil from the front and rear sights. Using a toothpick or similar applicator, put a little dab of Testors gloss white model paint on the front sight, and a little dot on each side of the notch in the rear sight. Let it dry thoroughly.
Go to Wal-Mart and purchase their "glow in the dark" paint (in paint section, not craft section). It's about $12 for a few ounces of it. Again, use a toothpick or similar applicator to apply a layer of GITD paint on top of the white dots you've already painted. Let dry. Apply a second layer of GITD paint.
You now have "glow in the dark" sights. Line up the 3 glowing dots just like a combat pistol sight, and you're ready to go.
This paint doesn't glow for very long, so about 15-20 minutes before the end of legal light in the evening I "recharge" the paint by shining my 1-LED flashlight on the sight for about 30 seconds, cupping my hand over the light to ensure no light leakage to spook game or spoil my night vision. It doesn't take much light to recharge the GITD paint. This will yield sights that are visible until legal light and beyond.
I've applied this technique to all of my side-hammer guns, and to the sights on several slug guns owned by friends, all of whom very much appreciate this addition to their firearms. One bottle of GITD paint is good for more gunsights than you're likely to see in a lifetime! LoL
Just remember, just because you can see the sights doesn't mean you can see your target clearly, so the usual safety rules need to be vigorously applied in low light conditions.
Also, if you're looking for Tru-Glo or similar sights, DON'T purchase red fibre optics as these are the hardest for your eye to see in low light conditions. The human eye is optimized for blue/green colour, so the green Tru-Glo is the best choice. (I still can't figure out why most manufacturers of fibre-optic sights insist on using red fibres for the rear, or worse yet, the front sight element. They obviously don't understand very much about how the human eye works.)
