Sig Sauer M11A110 P229 M11 A1 9mm 3.90 inch 10+1 Hardcoat Anodized Nitron Slide

The Sig Sauer M11A110 P229 M11-A1 9mm Luger is a compact, duty-grade semi-auto pistol that blends the P229 series� decades-long law enforcement pedigree with a carryable 3.90" barrel and 10+1 capacity, ideal for off-duty carry, plainclothes assignments, and range work. Its aluminum alloy frame with black hardcoat anodized finish keeps weight down to 29.6 oz while delivering rugged durability, and the serrated black Nitron stainless slide and vertical front strap serrations give reliable slide manipulation under stress or with gloves. The DA/SA action and manual thumb safety provide a deliberate first double-action pull with an immediate single-action follow-up for controlled shooting, paired with SigLite night sights for low-light target acquisition. Ergonomic black polymer grips sit naturally in the hand for consistent recoil management with 9mm Luger rounds, and a 3.90" barrel balances concealability with ballistic performance. As a regulated firearm, transfer requires an FFL, and the M11-A1 designation ties this model to Sig Sauer's compact M11 family used by federal and local agencies, making it a sensible choice for professionals and experienced shooters seeking a proven service pistol for duty, defense, or regular training.
