Check out XS Sight Systems online. I prefer the Standard Dot Tritium for precision. The Big Dot is just too BIG. I believe this particular version is set to be discontinued; so, act fast if you’re interested. Installation requires machining the front sight into a stud, according to the precise measurements in the instructions.* Then the sight is epoxied onto the stud. Works very well:

The Standard Dot covers most of the black bullseye at 15 yards.

Just installed one on my recently acquired 3” 940 a couple weeks ago:

*If one is patient, works slowly, and measures often, it would be possible to do this with only a file and a caliper. I took the easy way, imposing on a machinist friend who owed me a favor.

Every day’s an adventure.
