Sig Sauer P322 Adjustable Fiber Optic Rear Sight

This iron sight is an original factory replacement for the Sig Sauer P322 and helps you find a proper alignment faster and with greater clarity. Thanks to the green fiber optic inserts, your notch lights up beautifully, which is particularly useful when you want to quickly reacquire your sight picture.

What we think of this iron sight for your Sig Sauer P322

We consider this a surprisingly refined upgrade compared to standard iron sights. What stands out immediately is that the green fiber optic dots contrast beautifully against the matte black housing — your eye is naturally drawn to them. The fact that this is an original Sig Sauer component means the fit is spot on and you won't need to make any adjustments to get it seated properly.

Technical and optical performance of this iron sight

The core of this sight lies in the combination of adjustability and visibility. You can adjust both windage (lateral adjustment) and elevation (vertical adjustment), allowing you to fine-tune your sight picture precisely to your preference and use. The green fiber optic inserts capture ambient light and convert it into two bright reference points, giving you quick orientation under varying lighting conditions.

In terms of construction, the housing is finished in a clean black colour that reduces glare. It is a front and rear sight component manufactured to the same standards as the original parts in your Sig Sauer. Would you like to know more about exact dimensions or specifications?

Fitting and compatibility

This iron sight is specifically designed as a direct replacement for the rear sight of the Sig Sauer P322. As it features a factory-matched fit, it slides directly into the existing dovetail recess of your slide, exactly as the original component did. No separate mounting rail or adapter is required — it is a direct 1-to-1 replacement.

This is a standalone sighting component (the rear sight itself), without an additional mounting kit. Installation can be carried out using standard sight adjustment tools, allowing you to replace everything neatly and without causing any damage.

Who is this iron sight intended for?

This iron sight is ideal for P322 owners looking to upgrade their standard rear sight to a more visible and adjustable alternative. Whether you are an enthusiastic sport shooter who wants to fine-tune their sight picture to perfection, or someone who simply wants more contrast and speed when aligning: the adjustable windage and elevation combined with the fiber optic inserts make it an excellent choice for static shooting setups and training sessions.
