Frequently Asked Questions
Sig Sauer M11 A1 for sale
What is a SIG M11 A1?
The SIG M11-A1 is a compact 9mm pistol built on a P229 platform designed to replicate the P228, built to military specifications. It features a double-action/single-action trigger, phosphate-coated internals for corrosion resistance, and is used by U.S. military and law enforcement for concealed carry and personal defense.
Is the SIG M11-A1 reliable?
Yes. The M11-A1 is generally considered reliable, featuring a stainless steel slide, phosphate-coated internals, and corrosion-resistant construction. It handles +P ammunition safely. Users report strong performance with minimal maintenance, making it a dependable choice for carry and defensive use.
What makes the M11A1 unique?
The M11-A1 is built on the P228 platform, featuring a folded carbon steel slide, removable breechblock, and internal extractor. Phosphate-coated internals provide saltwater corrosion resistance. Its compact frame, short reset trigger, and plain dust cover make it well suited for military use and concealed carry.
How does the M11A1 handle recoil?
The M11-A1 uses a double-recoil-spring assembly and full-length slide rails to distribute recoil forces evenly. Its metal frame produces smooth, linear recoil, though shooters may feel it more than with polymer-framed alternatives like the Glock 19. The result is controllable and manageable, especially with higher-pressure 9mm ammunition.
Is SIG M11-A1 being discontinued?
Yes. SIG has discontinued all variations of the M11-A1. Our marketplace still shows 40 retailers listing it across 5 variants, with 3 currently in stock at a median price around $1,100, but these are remaining units. Once current inventory sells through, new stock will not be available.
Is the M11A1 good for concealed carry?
Yes. Its compact 9mm frame suits concealed carry well, with a 15+1 capacity that rivals full-size pistols. Striker-fired action, proven reliability, and compatibility with P228/P229 holsters make it practical for daily carry. Most listings run $900–$1,213, though availability is limited as production has ended.
What size magazine is the SIG M11?
The SIG M11 uses 15-round magazines. These are compatible with the SIG P229 platform, giving a capacity of 15+1 rounds when one is chambered.
What is the difference between P228 and M11A1?
The M11-A1 is the modernized successor to the P228, built on the P229 platform rather than being a direct P228 update. It features a blackened stainless steel milled slide (vs. the P228's stamped slide), SIG Lite night sights, phosphate coated internals, and holds 2 more rounds than the P228.
What caliber is the SIG M11-A1?
The SIG M11-A1 is chambered in 9mm. It is a compact pistol built on the P229 platform with a milled stainless steel slide and phosphate-coated internals, used by U.S. military personnel requiring a concealable sidearm.
How much is a M11?
The SIG Sauer M11-A1 typically costs around $1,200, with prices ranging from roughly $1,080 to $1,300 depending on the variant and retailer.
