Mac90, the Choate is nice. The front blade is a bit too thick, but it's still not as thick as the stock Ruger winged front sight.
If you have some moderate gunsmithing skills, installation is not bad, but otherwise you might want to take it to a gunsmith for install.
I have explained how to do it in detail on perfectunion, so won't go into it all here, but you need to get it straight up at 12 o'clock so you don't find later that you've used up all your windage to get zeroed. A cheap laser cartridge like the Sightmark will get you close.
You then use the bottom set screw to secure it long enough to check zero at the range, then you can drill the roll pin holes.
The Ruger steel seems very hard, be prepared to go slow with the drill press, and have a couple good bits for each roll pin hole.
I assume the guy you refer to on PU is FMJ50, of TrueShot Tecnologies.
If you like his designs, then go for it. I think you could contact him directly on his website without having to PM him.
The guy is a trip. He starts producing one of his new sights, THEN comes on the forum and asks our opinion.
Almost unanimously, we say it looks too big for a Mini, too blocky and sharp angled., and we'd rather have a pin on instead of a clamp on sight. He gets all defensive, and tells us he's already producing that design, can't change it now, and that we don't know what we're talking about. He has the worst customer skills of anybody I've ever seen. Threads that he starts always turn into a shitfest.
He did just come out with a design that is more in line with what we wanted, but still a clamp on. It took him a few years, but he is starting to come around to what the customer desires, instead of what HE thinks is cool looking.
I have threaded several Mini's with hand tools I got from Carolina Shooters Supply. Easier to do than the Choate and you can change the FH out for something else later if desired. With a newer Mini like you have, the winged front sight is already there.
I only used the Choate on a couple builds as I couldn't locate a take-off winged sight for my older Mini-30's to replace the fat single blade old style sight.
The Choate, already having a winged sight built in, was the next best option.
After doing the threading, it's a good idea to clean up the crown, also done with hand tools I got from Brownell's. It doesn't take much to improve on the factory crown job, this will also contribute to better groups.
Here is one of mine I threaded and put a Ruger FH on:
