I have done extensive use on both products to highlight their similarities and differences. In this Leupold DeltaPoint Pro vs Trijicon SRO guide let's cover what I liked and disliked.
Even through full force torque test wasn't done when reviewing these two red dot sights, but there are important specs that normal users will find helpful to make an informed purchase decision with this comprehensive side-by-side comparison guide.

Size & Weight
Trijicon SRO and DeltaPoint Pro are very different in their profiles. As far as weight goes, the Trijicon SRO is 0.4 oz lighter.
Leupold DeltaPoint Pro weighs 2.0 oz.
Trijicon SRO weighs 1.6 oz.
For the most part, 0.4 oz isn't that significant for the user to feel unless more accessories are added

Durability
I have used both optics for a while now, and it's our honest opinion that both optics hold zero (If properly zeroed), and the Leupold DeltaPoint Pro features a stronger front lens frame than Trijicon SRO the following environments:
- Hard slide rack against surfaces
- Straight drop
- Drop at dangle
The additional lens hood diverts impact stress away from the front lens like the EOTECH holographic sight
Another thing I like about the DeltaPoint Pro is that the adjustment button is inside the emitter enclosure so the button can't be push if it falls on the ground or carrying concealed.
The Trijicon SRO still work, and I will continue to put it through test and show its breaking point.
Glass Clarity
Glass clarity is good for both optics. However, they are all open emitter optics, which means debris can get into the enclosure and potentially obscure the LED emitter screen.
This isn't a big issue indoor, but outdoor with windy conditions is a problem where sand can get in there dirty up front and back of the glass.
Mounting Options
Trijicon SRO is a compatible RMR footprint optic, and the DeltaPoint Pro features a completely different footprint.
There are tons of aftermarket support for these two optics including:
- Adapter plates
- Offset mounts
- Piggyback scope mounts
The SRO can go on any RMR compatible mounts or pistol slides, and that's a great design to expand the RMR product line to further serve existing RMR users without the need to buy other proprietary accessories.
There are tons of aftermarket and Leupold brand mounts available for the DDP. Use it on handguns, pistols, shotguns or other offset configurations.
Reticle Effectiveness
Both optics feature simple center dot reticle system, and this is where dot size selection can steer the buyer in one way or the other.
The Trijicon SRO offers
- 1 MOA
- 2.5 MOA
- 5 MOA
Note: Parallax shift is noticeable at CQB distances for the Trijicon SRO and DeltaPoint Pro. No optic is 100% parallax free
The DeltaPoint Pro offers
- 2.5 MOA
- 6 MOA (Newer model)
Facts: Shooters with astigmatism may need vision correction to see a crisp dot.
When it comes to fast target acquisition for pistol applications, the bigger the dot the better. For most cases, the 6 MOA is the go to option for pistol & shotgun users.
The 5 MOA is big and it's not that much different than the 6 MOA dot purely based on looking at it with your own eyes.
None of the optic feature multi reticle modes, which means the user can't cycle through different dot sizes.
Go with Trijicon SRO 1 MOA model for anyone looking for a precise dot on rifle applications

Brightness Adjustment
Trijicon SRO's brightness adjustment button features more functionality such as lock out mode and auto brightness mode.
Total 6 Day light settings and 2 NV settings. Under a sunny day the dot is visible. For aiming directly into the sun, please read this article
Since the buttons are facing outward they are likely to be pressed by something, so the "Lock-Out" mode is ideal for everyday carry and hunting.
- SRO must be turned off (Hold both buttons for 3 seconds to turn off)
- Hold both buttons for 3 seconds to turn on the SRO in automatic mode (manual brightness settings locked)
"Lock-In" mode is similar to automatic brightness adjustment to match the ambient light.
- SRO must be on (Not in Lock-Out mode)
- Select desired brightness setting via "+" or "-" button
- Hold either button for 3 seconds (dot will blink and enter "Lock-In" mode)
DeltaPoint Pro's brightness control button is very simple to operate.
There is only one button to press, and it cycle through low and high. Total 10 brightness settings.
The only annoying part is that if adjusting too fast and skipped over the desired setting, the user has the cycle through the whole process again (Dot will flash 5 times when the highest or lowest setting is reached)
Just do it slow you will be fine.
Adjustment Turrets
Turrets on the DeltaPoint Pro is much more tactile than on the SRO for sure. For some reason, the SRO features a very dull turret adjustment experience where the user doesn't get a positive feedback for each click.
This can be extremely annoying to adjust the optic in the field when it's freezing cold with gloves on, windy conditions that you can't hear the click.
When it comes to turrets, the DeltaPoint Pro is way better no doubt. However, the SRO features total 150 MOA total travel combined elevation and windage, which gives the optic more room for zero especially on high height over bore guns.

Battery Life
Both the Leupold DeltaPoint Pro and Trijicon SRO use a CR2032 lithium battery for power, with long battery life. The Trijicon SRO has a longer battery life of up to 3 years with automatic and manual LED brightness adjustment. The DeltaPoint Pro has an average battery life of 300-600 hrs and it will run out faster if carrying it concealed or in the vehicle a lot. because it's never in idle.
Its built-in motion sensor is not as efficient as other optics like the Holosun 507C, which uses the same technology with a smaller CR1632 battery that can last up to 50,000 hrs. It is recommended to change the battery on the DeltaPoint Pro every 6 months.
