The DeltaPoint Pro and Trijicon SRO have something more similar than different besides how they look. 

In this guide, we take a look at DPP VS Trijicon SRO comparison side by side to help buyers make a purchase decision.

Overview

Leupold DeltaPoint Pro

Pros

  • Large field of view than most optic in this class
  • 6 MOA model now available
  • Additional lens hood to divert stress away from the main lens frame
  • Fogproof
  • Motion activated reticle to save battery even more (MSTTM, Motion Sensor Technology)
  • Top battery access to avoid sight removal for battery swap
  • As durable as Trijicon RMR

Cons

  • Low battery life. 1000 hrs on average
  • Slightly orange looking reticle than pure red

Trijicon SRO

Pros

  • FOV as big as Leupold DPP but circular 
  • Fast dot tracking without losing the reticle
  • Top loading battery access
  • 30 MOA more MOA adjustments than DPP
  • Same RMR mounting footprint to go on compatible slides and optic mounts
  • Much more affordable than Aimpoint ACRO

Cons

  • Lens frame is not duty grade like the RMR even though its 7075 T6 construction
  • Front extension may cause ejection port jam for some pistols

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 DPP 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

We 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 DPP 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 we 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 we 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

SRO is a compatible RMR footprint optic, and the DPP 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 (New 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.

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.

  1. SRO must be turned off (Hold both buttons for 3 seconds to turn off)
  2. 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.

  1. SRO must be on (Not in Lock-Out mode)
  2. Select desired brightness setting via "+" or "-" button
  3. 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 DPP 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 DPP 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 optics use a single CR2032 lithium battery to power the sight. As far as battery goes, both of them last long.

If you had to pick an optic based on battery life, the Trijicon SRO lasts longer up to 3 years with both automatic and manual LED brightness adjustment.

The DPP only lasts on average 300 - 600 hrs using the same LED emitter technology. The built-in motion sensor does work, but other optics like the Holosun 507C uses the same motion sensor technology with a smaller CR1632 battery can last up to 50,000 hrs.

Changing the battery every 6 months is a good routine for the Leupold DPP.
