Trijicon RMR Type 2 - Best Durability
The Trijicon RMR Type 2 is the gold standard red dot sight for the Glock 40. After using the Type 2 RMR on various handguns, it actually has a tighter battery grip for full electrical contact during repeated recoil cycles.
For competition shooters this design is well worth the money to ensure the dot doesn't die when you run through a timed stage and win the match.
Super Rugged Frame Body - Indestructible 7075 T6 forged aluminum body can survives drops, slam, shear and other "ouch" physical abuse to last a very long time before you need to buy another optic
Brightness Lockout Mode - The improved brightness lockout mode is great for conceal carry because I don't have to worry about accidental brightness adjustment under clothing
Long Battery Life - Even though it last up to 4 years, but still replace the battery every year
Various Dot Sizes - Trijicon RMR product line offers everything from 1 MOA to 6.5 MOA. 6.5 MOA is highly recommended for pistol use
Holosun 507C X2 - Best Overall
The Holosun HE507C is in my opinion the next best RMR footprint red dot sight and it actually has a bigger viewing window than the Trijicon RMR. It can mount on any direct milling Glock 40 slide or the MOS version with the Forward Design Control mounting plate.
Uses RMR Footprint - Use it on the Glock 40 and also be able to swap the optic onto a different gun using the same RMR mount.
Bigger Buttons - Adjustment buttons in the dark or day easily even with big fingers
Near Infinite Battery life - 50,000 hours of battery life + solar panel backup power if the battery goes out.
Side Loading Battery - No sight removal required for battery swap. Access the battery from the side tray
RMR Durability - Made overseas, but the durability is nearly identical to Trijicon RMR at a lower price point.

Cyelee Wolf X Pro - Best For The Money
The Cyelee Wolf X Pro is a brand new RMR footprint red dot sight that just stormed the budget red dot market out of nowhere. After checking out many reviews, I decided to get one and try it out.
The optic is very slick to go on the Glock 40 and it has thick lens frame for durable field use, and it features a multiple reticle system that many other budget red dot sights don't have.
The 26 MOA ring is actually great for close range shooting, but I can also switch it to just the 2 MOA center dot for precise aiming. I highly recommend this one for new and experienced shooters who don't want to buy another expensive optic.
The only thing I didn't like is that the turret dial doesn't give positive feedback for each click.
Trijicon SRO - Largest Viewing Window
The Trijicon SRO has the largest field of view for Glock 40 users. I got the Trijicon SRO back in 2019 when it first came out to the market, and I just loved that thing because I can acquire the dot and reacquire the dot much faster than anything else I have used in the past.
Even though it's not recommended for duty use. Who is going to carry a long slide Glock 40 ? Almost no one. The Trijison SRO is perfect for a competition range gun like the Glock 40, and it uses the same RMR footprint.
Besides the large window. The optic's battery can be accessed from the top instead of the bottom, which is Trijicon's first time releasing a product like this. In addition, I also like the reticle lockout feature that the original RMR doesn't have.
