We tested many red dot sights on pistols, and here best red dot for Walther PDP with great durability, fast aiming capability and battery life.

We picked them based on fit and aiming experience for range and carry applications. Optics are not judged based on extreme torture tests.

Let's check them out:

Best Walther PDP Red Dot Sights

Top 3 Options

Best Overall

Holosun 507C

  • 2 + 32 MOA Ring
  • RMR footprint

Largest FOV

Trijicon SRO

  • Faster dot acquisition
  • Top loading battery

Best Weatherproof

Holosun 509T

  • Enclosed emitter
  • Side loading battery

These optics fit even better on the new Walther PRO SD with deeper slide cut that feature recoil lugs.

Holosun HE507C X2 - Best Overall

holosun 507k x2 on walther pdp 9mm

The Holosun 507C X2 2 MOA red dot sight is one of the best pistol red dot sights for Walther PDP. It functions and feels like a Trjicon RMR and the battery lasts very long.

32 MOA Reticle - 32 MOA reticle increases shooter's chance to re-center the reticle even if it's slightly off center. Way better than a single dot

Battery Lasts A Long Time – Lasts over 100,000 hours, Solar Failsafe kicks in even if the battery fails to keep you in the fight longer

Super Strong Material That Lasts – Built with 7075 T6 aluminum, increased body strength and durability to handle the heaviest handgun caliber recoil impulses. 

Lockout Mode For CCW - Eliminates accidental brightness adjustment due to inadvertent button press while conceal carrying

Motion Activated Reticle –  The Shake Awake technology activates the reticle upon motion and turns off when sitting at idle


  • Magnification: 1X
  • Reticle: 1 MOA, 32 MOA ring, or combined
  • Turret Value: 1 MOA / Click
  • Field of View: 0.63" X 0.91"
  • Construction: 7075 T6 aluminum IP67 rated
  • Dimension: 1.78"X1.15"X1.15"
  • Weight: 1.5 oz
  • Battery Life: 3 - 4 years
  • Pros

    • Much more affordable than Trijicon RMR
    • Uses RMR footprint
    • Long battery life + motion sensor aviation + solar power
    • No sight removal required for battery swap


    • Visible distracting logo
    • Open emitter design attracts debris
    • Solar power doesn't work indoor

    Trijicon SRO - Largest FOV

    Recommend using shorter RMR screws or send to CHWPS for slide modification

    The new Trijicon SRO has a big lens frame for better dot tracking than any other standard size red dot sights. The best part is that it uses the same RMR footprint without buying custom mounting plates.

    Unobstructed Field of View - Bigger window than RMR, fast on target, fast follow up, Dot never leaves inside the window, Never lose the dot again!

    Easier To Find The Dot - Slightly enlarged upper portion of the window significantly increase dot acquisition speed even if the grip angle was off 

    Top Loading Battery Access - Improved user experience, access battery without removing the sight or re-zero the sight 

    Lock-In & Lock Out Mode - Saves user chosen brightness setting indefinitely, Ideal for target shooting & competition


    • Magnification: 1X
    • Reticle: 5 MOA option is the best
    • Turret Value: 1 MOA / Click
    • Field of View: Round 0.98" X 0.89"
    • Construction: 7075 T6 aluminum
    • Dimension: 2.2"X1.3"X1.4"
    • Weight: 1.6 oz
    • Battery Life: 3 - 4 years


    • Very large FOV for dot tracking
    • No zeroing or sight removal required for battery swap like the 507C
    • Same RMR footprint
    • 3 dot sizes offered, 1 MOA, 2.5 MOA and 5 MOA
    • Lockout mode


    • Not the same lens frame durability as RMR
    • A bit pricey

    Holosun 509T X2 - Best Weatherproof

    walther pdp with holosun 509T

    The new Holosun 509T X2 is a beefed up version of the 508T with a closed emitter red dot body to prevent debris from entering the optic either in the field or carrying concealed under clothing
