Sig P229 Red Dot Mount – Precision Mounting Without Slide Cuts

Looking to upgrade your Sig Sauer P229 with a red dot sight — but don’t want to mill your slide? You’re in the right place. Our P229 red dot mounts offer a secure, proven way to add an optic to your pistol, whether it’s a classic non-optic-ready model or a newer RX or Legion variant.


🔧 Red Dot Mounting Options for the Sig P229

We stock a variety of red dot mounting plates and adapters, including:

  • Dovetail Red Dot Mounts
    Replace your rear sight and install a red dot without any permanent modifications. Perfect for classic P229 models.

  • Optics-Ready Adapter Plates
    Have a P229 RX, Legion, or Pro Cut slide? Choose a high-grade steel mounting plate matched to your optic’s footprint — RMR, Holosun, Aimpoint, and more.


Why Our Sig P229 Red Dot Mounts Stand Out

🔹 No Slide Milling Needed – Keep your factory slide intact
🔹 Built from Steel – CNC-machined for strength and reliability under recoil
🔹 Multiple Footprint Options – Compatible with:

  • Trijicon RMR & SRO

  • Holosun 507C, 407C, 508T, 509T

  • Vortex Venom / Viper

  • Burris FastFire

  • Aimpoint Acro

🔹 Easy DIY Install – Includes hardware and tools where needed
🔹 Trusted Fit – Used by everyday carriers, law enforcement, and competitive shooters


🛠️ Installation Made Simple

Installing a red dot on your P229 doesn’t have to be complicated:

  • For non-optic-ready slides: Remove your rear sight, slide in the dovetail mount, and attach your optic

  • For optics-ready slides: Remove the factory plate and replace it with one that matches your optic’s footprint

We recommend using threadlocker (Blue Loctite) and a torque wrench for proper tension. Not sure what fits? Reach out — our support team shoots what we sell.

FAQ

Q: Can I install a red dot on a Sig P229 without modifying the slide?
A: Yes — use a dovetail mount that replaces your rear sight. It’s fully reversible and doesn’t require milling.

Q: What optics work with your P229 mounts?
A: We support Trijicon RMR, Holosun 507C/508T/509T, Aimpoint Acro, Vortex Viper, Burris FastFire, and more. Be sure to match the optic’s footprint with your plate.

Q: Will these mounts fit my P229 RX or Legion?
A: Yes. These models are optics-ready from the factory. You’ll just need the correct adapter plate to match your optic.

Q: Can I co-witness iron sights with my red dot?
A: Generally, you’ll need suppressor-height sights to co-witness with most optics, especially if using a dovetail mount.

Q: Is this mount secure enough for duty or carry use?
A: Absolutely. Our mounts are made from steel, built to handle recoil, and trusted by law enforcement and experienced shooters alike.
