Sig Sauer
Authorized Dealer • Newington, New Hampshire • Swiss-German Heritage Since 1976
Sig Sauer is the Swiss-German firearms house that emerged from the 1976 collaboration between SIG (Schweizerische Industrie-Gesellschaft) of Neuhausen am Rheinfall, Switzerland, and J. P. Sauer & Sohn of Eckernförde, Germany — the partnership that produced the legendary P220, P226, and P229 duty pistols. Today Sig Sauer Inc. is the dominant American manufacturing arm headquartered in Newington, New Hampshire, holder of the US Army M17/M18 Modular Handgun System contract that replaced the Beretta M9 in 2017. Keep Shooting's Sig catalog spans the full breadth of the brand — the P322 .22 LR pistol, the P6 surplus West German police P225, the Romeo red-dot optics line, OEM magazines for the P320, SP2022, and 1911 platforms, plus M17 and MPX air-gun trainers.
Sig Sauer at Keep Shooting
Sig Sauer is the Swiss-German firearms partnership born in 1976 when SIG (Schweizerische Industrie-Gesellschaft) of Neuhausen am Rheinfall, Switzerland, joined forces with J. P. Sauer & Sohn, the Eckernförde, Germany maker tracing its roots to 1751. The collaboration produced one of the most influential pistol families of the late 20th century: the P220 (single-stack .45 ACP), the P226 (the duty pistol adopted by Navy SEALs, the FBI HRT, the British SAS, and dozens of other tier-one units worldwide), the P228 / P229 compact duty pistols, and later the striker-fired P320 that won the US Army's Modular Handgun System trial in 2017 to become the M17 / M18 service pistol — replacing the Beretta M9 after three decades of US military service. Today Sig Sauer Inc. operates as a US firearms maker headquartered in Newington, New Hampshire, producing pistols, rifles, the Romeo, Tango, and Kilo optics lines, ammunition, suppressors, and the Sig Sauer Academy training operation. The Keep Shooting catalog covers a cross-section of every major Sig product category with seventeen SKUs spanning firearms, surplus handguns, optics, magazines, gun parts, and air trainers.
P322 — The Optics-Ready .22 LR Pistol
The Sig Sauer P322 (model 322CBAS10) is Sig's 2022 entry into the .22 LR pistol market, designed from the ground up as an optics-ready, threaded-barrel, 20-round rimfire platform — with the full-size grip ergonomics of the P320 and the same Sig manual-of-arms that defines the Sig duty line. Where most .22 LR pistols target the casual plinking market with budget construction, the P322 was engineered as a practice-and-training analog for shooters who run a P226, P229, or P320 as their carry or duty gun and want a low-cost, low-recoil pistol with the same trigger feel, the same grip angle, and the same optics footprint for high-volume practice. The threaded barrel accepts standard 1/2x28 TPI rimfire suppressors (Silencerco Sparrow, Dead Air Mask, Rugged Mustang) without an adapter. For shooters comparing .22 LR pistol options, the P322 occupies the premium tier that Ruger's Mark IV 22/45 and S&W's Victory also compete for.
P6 — The Surplus West German Police P225
The Sig Sauer P6 is the West German police-service designation for the SIG-Sauer P225 single-stack 9mm pistol — issued from the late 1970s through the 2000s to West German federal and state police forces, and one of the few opportunities on the civilian market to own a documented surplus Sig from the original Neuhausen-and-Eckernförde-era production run. The P225 was developed in the 1970s German police trials that called for a slimmer, more concealable 9mm than the full-size P220 / P226, with a hammer-down decocker and a magazine disconnect. The P6 variant adds the surplus markings, the original West German police lanyard loop, and the issued holster wear that documents the gun's service history. For collectors and surplus enthusiasts, the P6 is a Sig pistol with provenance — production and issue in a specific era, by a specific agency, in a specific country — not just a current-production gun.
Romeo Optics — Red Dots and the Juliet Magnifier Combo
Sig Sauer entered the electro-optics market in 2014 and rapidly became one of the largest American optics makers, with the Romeo red-dot line covering pistol-mounted micro dots through full-size rifle dots, Tango scopes for precision rifles, and Kilo rangefinders for hunting. Keep Shooting carries three Romeo SKUs: the Romeo MSR Gen II compact rifle red dot designed for the modern sporting rifle (MSR) class — AR-15, AR-10, and pistol-caliber carbines — the Romeo 5 XDR Gen II (1x20mm, 2 MOA dot, the most-installed Sig dot in the entry-level AR optic market), and the Romeo MSR Gen2 + Juliet3-Micro combo which pairs the MSR red dot with a 3x flip-to-side magnifier on a single quick-release rail mount — the canonical “dot for close, magnified for far” setup that works on a single-platform rifle without committing to a fixed LPVO.
The M17 / P320 Ecosystem at Keep Shooting
The P320 is the modular striker-fired platform that became the M17 (full-size) and M18 (compact) US Army service pistols after the Modular Handgun System trial in 2017. Its defining feature is the serialized Fire Control Unit (FCU) — in the P320, the FCU is the actual legally-controlled firearm, and the grip module, slide, and barrel swap freely around it. That makes the platform almost uniquely customizable among duty pistols. Keep Shooting stocks four P320-ecosystem SKUs: the P320 21-round Coyote Magazine (the extended-capacity 9mm magazine, in the Coyote tan finish that matches the M17 FDE service-issue color), the P320 Compact Threaded Barrel (M13.5x1) for suppressor and compensator mounting, the P320 TekMat workbench cleaning mat, and the M17 CO2 Pistol air-gun trainer (the licensed-replica air version of the military M17 for low-cost backyard practice with the same grip ergonomics and manual of arms).
P226 / P229 Heritage — The Classic Duty Pistols
Before the P320 dominated the modular-pistol conversation, the P226 and P229 defined the Sig duty line for three decades. The P226 was Sig's entry into the 1984 US XM9 service-pistol trial that the Beretta M9 ultimately won — but the P226 went on to be adopted by US Navy SEAL Teams (as the Mk 25), the FBI Hostage Rescue Team, the British SAS, and law enforcement agencies worldwide. The P229 is the compact-frame version that became the standard duty pistol for US federal agencies including the Secret Service, the Federal Air Marshals, ICE, and the State Department's Diplomatic Security Service. Keep Shooting carries TekMat workbench cleaning mats for both platforms: the P226 TekMat and the P229 TekMat, plus the SP2022 Magazine (the spiritual successor to the P229 in Sig's polymer-frame duty line, now adopted by the French National Police).
1911 Platform — Sig's American Classic
Sig Sauer's 1911 line is the company's American-classic platform — the traditional single-stack .45 ACP design in Sig fit-and-finish, with a number of rail-equipped and tactical variants. Keep Shooting carries OEM magazines for both frame sizes: the Sig 1911 Full Size 8-round .45 ACP magazine for Government-length 1911s and the Sig 1911 Compact magazine for the Compact frame. The Sig 1911 .22 thread adapter rounds out the 1911-platform support for owners running a .22 LR conversion kit on their Sig 1911 frame.
Tactical Knife and Air-Rifle Trainer
Two SKUs round out the catalog and reflect Sig's modern lifestyle-brand expansion. The Sig Compound Tactical OTF Auto Knife is an out-the-front automatic knife in the modern tactical-EDC tradition — push-button blade deployment, partially serrated edge, tanto-style point. The Sig MPX Air Rifle is the .177 caliber CO2-powered air-gun replica of the Sig MPX 9mm submachine gun platform, sharing the same controls layout and AR-style ergonomics — a backyard and indoor-range trainer that lets shooters build manual-of-arms familiarity with the MPX without the cost or storage burden of a real submachine gun.
