There are a lot of "proprietary cuts" out there for sights these days.
Back when Swenson was improving the 1911,
the standard was the S&W adjustable sight. We've come a long way.
Heinie and Novak are the most popular aftermarket sights. So most custom cuts follow one of those two patterns, and usually the customer is given the option before the custom work is begun. The cuts are different. Now, every 1911 shop it seems comes out with their own proprietary sight, and corresponding cut. Kimber's cut only fits Kimber's sights. So if you want to change your sight - or replace it, because remember tritium is only good for 10 years tops - you'll have to go back to Kimber, or whoever Kimber has licensed to make a sight using their cuts.
I've seen Smith & Wesson, Sig, and all the other players in the game go the same route. The Smith and the Sig 1911's have so many proprietary parts and cuts on them you're extremely limited in what options you have. I have no idea what Taurus is doing. I'd suggest you call them and ask what cut pattern they're using.
I don't like night sights. They have their place, and I can appreciate them for what they are. But you have to train with night sights,
in dim light, before they become an advantage. Until we reach that point, night sights are actually counter-productive. They'll play with our eyes and slow us down considerably. It takes a good bit of practice, I'd say about 500 rounds in low light shooting, until we clear that hurdle. I'd suggest it takes over 1,000 to 1,500 rounds to really master and take full advantage of night sights in low light conditions.
Me? I prefer 100 year old technology.

They never go bad and never tarnish. And because they don't produce their own light, but rather reflect any available ambient light, they don't take as much time to master.
