Sig Sauer LPA P226 X-Five LPA 3,75mm Flat Rear Sight

• 3.75 mm flat rear notch: The flat rear profile and defined notch give a clean sight picture that helps the front sight stand out, making fast alignment easier on a competition-style Sig Sauer pistol.
• Built for the P226 X-Five platform: A model-specific fit helps maintain proper sight geometry on compatible pistols, which matters for consistent point of aim and predictable handling.
• Steel construction: A steel rear sight stands up better to repeated holster use, slide movement and regular range work than softer materials, helping the pistol keep its zero over time.
• Black finish: The non-reflective black surface reduces distracting glare in bright light and keeps the rear sight visually subdued so attention stays on the front sight.
• LPA competition sight heritage: LPA focuses on handgun sight systems for sport and practical shooting, so the design reflects the needs of shooters who want a precise, durable replacement rear sight.

About the LPA Series

LPA handgun sights are built around a straightforward idea: give shooters a more precise and more durable alternative to factory sights without making the pistol unnecessarily bulky. Across its pistol sight range, LPA offers solutions for semiautomatic pistols, revolvers, shotguns and rifles, with product families that include adjustable and semi-adjustable sights as well as fiber-optic and Luminova-equipped variants. That broad catalog places the brand firmly in the practical shooting and hunting optics space, where sight visibility, repeatability and mechanical strength matter more than cosmetic extras.

Within the lineup, the company’s rear sights are known for their solid steel construction and compact profiles. Many are intended for shooters who want a cleaner sight picture, more precise alignment or a replacement part matched to a specific handgun platform. The design philosophy is functional: keep the sight picture clear, keep the body robust, and keep the fit appropriate for the host firearm. For sport pistols in particular, LPA sights are aimed at users who value a crisp rear reference and dependable construction for regular range use, action shooting and target work.

About the Sig Sauer LPA P226 X-Five LPA 3,75mm Flat Rear Sight

The Sig Sauer LPA P226 X-Five LPA 3,75mm Flat Rear Sight is a dedicated rear sight for compatible Sig Sauer P226 X-Five pistols, intended for shooters who want a simple, durable and competition-oriented rear reference. Its defining feature is the 3.75 mm flat rear notch, which gives the eye a clear window around the front sight. In practice, that helps the shooter separate the front blade from the rear sight quickly, which is useful both for deliberate target shooting and for faster strings where clean alignment matters.

The sight’s black finish supports that same goal by keeping the rear sight visually quiet. Instead of drawing attention with bright elements, it lets the front sight remain the focal point, which many shooters prefer for precision work. Because it is a steel rear sight, it is also suited to repeated slide cycling, handling and routine range use, making it a sensible replacement for a worn or less defined factory unit.

As a handgun rear sight rather than a full sight set, this model is best understood as a focused upgrade: it refines the sight picture and preserves a low-profile, practical form. For P226 X-Five owners who want a rear sight that emphasizes clarity, durability and a competition-style visual layout, this LPA unit keeps the pistol’s aiming system simple and effective.
