Description
The Burris FastFire Mount for the SIG Sauer P226 is the dedicated piece that bridges the gap between your pistol and your red dot. It replaces your factory rear sight and uses the slide's dovetail cut to give any generation FastFire sight a secure, repeatable home. If you've been running irons on your P226 and want to add the speed of a reflex optic, this is the clean way to do it without sending the slide off for a milling job.
What the P226 FastFire Mount Actually Does
This is a two-piece setup. A dovetail block drops into the rear sight slot, and the mounting plate sits on top, giving your FastFire a flat, rigid base to bolt down to. It carries the Docter footprint, so it's built around the FastFire family and works with any generation of the sight. The matte black finish keeps things low-key and matches the look of a factory SIG without any flashy contrast.
Installing the FastFire Mount on Your SIG P226
Mounting is a mechanical job, not a plug-and-play one. You'll drive out the factory rear sight, center the dovetail block in the slot, then set the plate and sight on top before snugging everything down. A sight pusher or a brass punch makes the job cleaner, and plenty of folks have their local gunsmith knock the old sight out if they'd rather not put a slide in the vise themselves. Blue thread locker on the screws is a smart move, and keeping light forward pressure as you torque helps everything sit square.
This mount is meant for standard, non-optics-cut P226 slides that still wear a rear sight dovetail. If your pistol already came milled from the factory with an optics cut, you'd use SIG's plate system instead. For everyone running a classic P226 and looking to go red dot without permanent slide work, this is the tried-and-true route.

Frequently Asked Questions
Which red dots work with the FastFire mount for the P226?
This mount is built for the Burris FastFire line and accepts any generation of the FastFire red dot. It uses the Docter footprint, so sights sharing that pattern will line up with the mounting holes. It is not designed to carry optics from other footprint families.
Will this fit my P226 if it already has an optics cut from the factory?
No. This mount replaces the rear sight and installs in the slide's dovetail, which is the setup for standard P226 slides that are not milled for an optic. If your pistol came factory optics-ready, you'd want to use SIG's dedicated plate system for that cut instead.
How does the FastFire mount install on a SIG P226?
You drive the factory rear sight out of its dovetail, center the included dovetail block in the slot, then seat the mounting plate and sight on top and torque the screws down. A sight pusher or brass punch makes removing the old sight easier, and a dab of blue thread locker on the screws is recommended. Many owners have a gunsmith press out the rear sight if they'd rather not do that step at home.
Does the FastFire mount come with the screws I need?
Yes, the mounting hardware comes in the package, so you get the dovetail block, plate, and screws needed to attach your FastFire. You will still need your own FastFire sight, since the optic is sold separately. Blue thread locker is not included but is worth adding.
