The P226 X-Five Classic is what SIG builds when the brief is "no compromises." Stainless steel frame, stainless steel slide, stainless FCU — a pistol that weighs 45.6 ounces and shoots like it. The trigger is a fully adjustable single-action-only AX3 system, the grips are custom Hogue cocobolo with an integral alloy magwell, and the slide is optic-ready with SIG's SIG-LOC system. It ships with three 10-round steel magazines. Part number 226X5-9-CL2-SAO-10, UPC 798681721597.

All-Steel, Single Action Only

Everything structural on this pistol is stainless steel — frame, slide, and fire control unit. That mass is the entire design thesis: at nearly three pounds, muzzle rise essentially disappears and the sights return to the same place shot after shot. The action is single action only with a manual safety, so the trigger pull is identical on every shot from the first.

Fully Adjustable AX3 Trigger

The AX3 trigger system is adjustable for pre-travel, over-travel, and pull weight — not preset at the factory and left there. That level of adjustability is normally the province of custom pistolsmiths. The trigger shoe itself is curved.

Sighted and Optic-Ready

Irons are a fiber optic front with an adjustable rear, over a 6.8" sight radius — unusually long for a handgun, and a direct contributor to the pistol's accuracy. The slide is an XSeries SIG-LOC optic-ready slide using the PRO footprint. No optic is installed from the factory.

Cocobolo and Magwell

The grip module is custom Hogue cocobolo — genuine hardwood, not a polymer imitation — with an alloy magwell integrated rather than bolted on. An M1913 accessory rail runs under the dust cover.

SIG P226 X-Five Classic Specifications

Who This Pistol Is For

Collectors, bullseye and precision pistol shooters, and P226 devotees who want the definitive version of the platform. It is not a carry gun and was never meant to be — this is a range and competition pistol, and one of the finest production 9mms SIG has ever built.

Frequently Asked Questions

Is the trigger flat or curved?

Curved. SIG's spec sheet lists "SAO AX3 System / Curved Trigger" — despite the competition positioning. It is fully adjustable for pre-travel, over-travel, and pull weight.

Is the magwell included?

Yes — the alloy magwell is integral to the Hogue cocobolo grip module, not a separate accessory.

Can I mount an optic?

Yes. The slide is SIG-LOC optic-ready using the PRO footprint. No optic ships installed.

Why only 10-round magazines?

This SKU is the 10-round configuration for capacity-restricted jurisdictions. SIG offers an otherwise identical SKU with three 20-round steel magazines with alloy basepads.
