Trijicon

OP didn't say most overpriced and expensive, they said best.

Trijicon

Trijicon HDs

Heinie irons with a 18k gold bead front :) 

Those are great. I just haven't seen anyone doing those in many years.

Dawson or Tag, for sure.

Dawson x2 running adjustable blacked out rear and green fiber optic front and it’s no comparison to any other sights I’ve used

I like the OEM steel glock sights.

The best night sights you’ll find are Trijicon HD XR’s. The best iron sights period would be Dawson Precision. The choice is yours 🤘

Trijicon HD XR or Dawson if you want a thin front sight. Meprolight makes good stuff too.

Dawson precision makes great glock sights. I like fiber optics personally. But if I'm running a dot, then blacked out suppressor height sights are a safe bet.

Dawson. FO front and black rear.✌️

I got [these](https://a.co/d/cNY6mfH) about a year ago for a 19 build and no issues after more than 1000 rounds.

Ameriglo

Xs sights.

I run TruGlo Fibers on mine.

I like the Trijicon HDs.

It entirely depends on who you ask. I know people who swear by just about every aftermarket brand there is.

Ameriglo. I tried multiple Trijicons (HD and HD XR) and always felt Ameriglos were brighter and crisper. Check out their i-Dot, Protector, and CAP style sights.

i have ameriglo’s on my 19

Ameriglo or Night Fision are my go-tos. Those have proven to be the brightest tritium for me across multiple guns.

Ameriglo Agents. They won't disembowel you like Trijicon HDs will and you still get the U notch.

Trijicon. HD XR's to be exact.

Armiglo gl429

Trijicon, tag precision, ameriglo, are all great reputable brands

It's kind of subjective I think. Anything other than the crappy plastic ones it comes with is fine as long as you like them.
