I have only owned a few guns that had night sights. I currently only own one. IMO they are a waste of money that could be applied towards a gun light or a crimson trace laser sight. Reason being is at some point they always go dim. You can replace the batteries in the gun light and laser sight.
What am I not understanding about the value of good night sights ?
Good tritium sights should last 10 years from the date of manufacture. At the end of 10 years, if you still own that gun, you replace the sights. Now, compare the money you spent in batteries for a WML and/or laser over a 10 year period to the cost of a set of tritium sights.
No reason to not have BOTH. I use both tritium sights and a WML. One is not a substitute for the other, rather they work together as part of a system.
I’ll admit, if I could only have one, I’d take the WML. Since it’s America and I can run whatever I can afford, I use both.
