The Steyr S-A1 (most commonly designated Steyr S9-A1 in 9mm) is a subcompact, polymer-framed striker-fired pistol featuring Steyr's signature low bore axis, trapezoidal sights, and Reset Action System trigger.
This Austrian-made concealed carry pistol features a 3.6-inch barrel in a polymer frame measuring approximately 6.8 inches in overall length, 4.8 inches in height, and 1.2-1.3 inches in width, weighing approximately 26.7-27 ounces unloaded. Standard capacity reaches 10+1 rounds from steel magazines.
Steyr introduced the S-A1 in 2004 as the subcompact member of their third-generation A1 pistol family. While effectively superseded by the A2 MF series and newer ATC/ATD platforms, the S9-A1 remains highly regarded among enthusiasts for its exceptionally soft recoil and quality trigger.
What Makes the Steyr S-A1 Stand Out Among Subcompact Pistols?
The Steyr S-A1 pistol represents one of the softest-shooting subcompact 9mm pistols available, offering recoil characteristics that rival larger pistols thanks to Steyr's innovative low bore axis design. This Austrian-engineered platform delivers refined shooting characteristics in a genuinely concealable package.
Steyr Arms, based in Austria, manufactures firearms with centuries of engineering heritage. The company positioned their S-A1 to compete with the Glock 26 and similar subcompacts for concealed carry applications.
Despite strong performance characteristics, limited U.S. marketing and sporadic import patterns have kept the platform relatively unknown outside enthusiast circles.
The S-A1's lineage traces to the original Steyr M-series introduced in 1999. The "A1" designation indicates the third-generation update from 2004, adding the accessory rail and revised grip. The S-A1 serves as the smallest variant in Steyr's A1 family, sharing slide and barrel length with the C-A1 compact while reducing grip height for enhanced concealment.
Steyr designed the S-A1 specifically for concealed carry where shooters demand refined shooting characteristics in a compact package. The platform targets serious carriers who prioritize controllability and trigger quality, particularly those seeking alternatives to mainstream subcompacts that may shoot more harshly.
What Are the Complete Specifications of the Steyr S9-A1?
The Steyr S9-A1 chambers 9mm Luger with 10+1 capacity from steel magazines. It measures approximately 6.8 inches in overall length with a 3.6-inch barrel, stands 4.8 inches tall, spans 1.2-1.3 inches wide, and weighs approximately 26.7-27 ounces unloaded.
Caliber Options
The S-A1 platform shipped primarily in 9×19mm (S9-A1), with a .40 S&W variant also produced (S40-A1). The 9mm configuration provides the most common capacity at 10+1 rounds. The .40 S&W variant offered the same 10-round capacity with increased terminal energy at the cost of additional recoil.
Dimensions
Overall length reaches approximately 6.8 inches (172mm)—compact enough for effective concealed carry. Height measures approximately 4.8 inches with the shortened subcompact grip designed for concealment.
Width runs approximately 1.2-1.3 inches (33mm), enabling comfortable IWB and appendix carry.

Unloaded weight reaches approximately 26.7-27 ounces (about 1.67 pounds). The S40-A1 variant weighs slightly less at approximately 23.9 ounces. This moderate weight contributes to the platform's soft shooting characteristics while remaining reasonable for concealed carry.
Magazine Capacity
Standard steel magazines hold 10 rounds for 10+1 total capacity—competitive with the Glock 26 class when the S-A1 launched, though now trailing modern micro-compacts with higher capacities. The shortened grip accommodates these magazines while maximizing concealment.
Barrel Specifications
The barrel measures 3.6 inches (approximately 92mm). Steyr's cold hammer-forged construction creates durable, accurate barrels. This barrel length matches the C-A1 compact variant, providing identical slide dimensions while the grip height differs for concealment optimization.
How Does the Steyr S-A1 Design Achieve Its Soft-Shooting Reputation?
The Steyr S-A1 features a polymer frame with an integrated Picatinny accessory rail and an extremely low bore axis positioning the slide closer to the shooter's hand than most competitors. The Reset Action System trigger provides smooth take-up and clean break superior to most striker-fired triggers. Steyr's proprietary trapezoidal sights offer rapid target acquisition.
Frame and Slide Construction
The polymer frame incorporates ergonomic grip sculpting with integral finger grooves sized for the subcompact configuration. The shortened grip differentiates the S-A1 from the C-A1 while both share the same slide and barrel dimensions. The steel slide receives quality finishing for durability and corrosion resistance.
Low Bore Axis Design
The S-A1's extremely low bore axis represents its defining characteristic—often compared to the legendary HK P7's sight height.
This geometry reduces muzzle rise and softens perceived recoil, leading reviewers to describe it as "one of the softest-shooting 9mm pistols I've ever fired." The low slide profile combined with high tang position enables exceptional control for a subcompact.
Ergonomics and Grip Design
The grip design earns consistent praise. Ergonomic sculpting and a natural pointing angle create comfortable handling even for shooters with smaller hands. Testers noted that even female shooters with smaller hands found no issues. The subcompact grip height reduces printing while the grip angle and texture maintain secure purchase during firing.
Trapezoidal Sight System
Steyr's proprietary triangular front and trapezoidal rear notch sight system provides rapid alignment by focusing attention on the front sight. This unconventional design polarizes users—some appreciate the fast acquisition while others find it slower initially and wish for traditional three-dot options. Limited aftermarket alternatives complicate sight changes.
Trigger System
The Reset Action System trigger represents a major S-A1 strength. This partially pre-cocked striker system provides smooth take-up with a clean break—"significantly improved over earlier Steyr pistols" and "better than most striker-fired triggers." The short reset aids fast follow-up shots. Reviewers note that aftermarket trigger parts "aren't needed" given the quality of the factory trigger.
Safety Systems
Internal safeties include a trigger safety, drop safety, and loaded-chamber indicator. Some models incorporate an optional key-operated manual trigger safety integrated into the frame. Standard U.S. S-A1s rely on internal safeties only, providing adequate passive safety without requiring manual manipulation.
Accessory Rail
The integrated Picatinny-type accessory rail on the dust cover accommodates lights and lasers—notable for a subcompact of this era. This capability enables defensive setups with proper target identification tools.
What Variants of the Steyr A1 Family Exist?
Steyr produced the A1 family in multiple frame sizes: the S-A1 subcompact, C-A1 compact, M-A1 mid-size, and L-A1 long-slide. The S-A1 shipped in 9mm (S9-A1) and .40 S&W (S40-A1) configurations. The platform has been effectively superseded by the A2 MF series and newer ATC/ATD designs.
S-A1 Subcompact (S9-A1/S40-A1)
The S-A1 represents the most concealment-oriented A1 variant. The 3.6-inch barrel matches the C-A1 compact, but the shortened grip reduces height for improved concealment. The 10-round capacity reflects the subcompact grip dimensions.
C-A1 Compact
The C-A1 shares the same slide and barrel length as the S-A1 but features full-height grip accommodating 15-round magazines. This configuration bridges concealment and capacity, offering better grip purchase for shooters willing to accept slightly reduced concealment.
M-A1 Mid-Size and L-A1 Long-Slide
The M-A1 provides mid-size dimensions with 4-inch barrel and 17-round capacity for duty and home defense. The L-A1 long-slide extends to 4.5 inches for competition and maximum accuracy potential.
Evolution to A2 MF and Beyond
The A2 MF series (C9-A2 MF, M9-A2 MF, L9-A2 MF) represents the successor generation with modular frames, improved texturing, and updated controls.
