SIG SAUER XCARRY P226 LEGION SAO CONCEAL CARRY. Optics ready 3.8-inch barrel NO TRADES AX1: Single-Action The 2026 single-action only (SAO) SIG Sauer P226 X-Carry Legion offers significant benefits in performance and ergonomics for both carry and competition use. The primary advantage of the single-action only mechanism is a lighter, crisper, and highly consistent trigger pull compared to traditional DA/SA models. Key Benefits of the SAO Trigger Consistent Trigger Pull: The SAO mechanism ensures every shot has the same light, short pull and crisp break, which is a major advantage for accuracy and fast follow-up shots. Adjustability: The AX1 trigger system in the SAO model features one-way over-travel adjustment, allowing the shooter to fine-tune the trigger feel to their specific preference. Enhanced Precision: A lighter trigger pull, typically around 3-4 lbs (compared to a 10 lb DA pull on DA/SA models), makes it easier to shoot accurately, especially at distance or when shooting rapidly. Positive Manual Safety: The SAO variant includes an ambidextrous thumb safety, similar to a 1911, which many shooters prefer for a consistent manual safety mechanism when carrying a round in the chamber.
