Three backstraps and two side-panel sizes typically ship with the pistol, enabling shooters to tailor fit. The steel slide receives Steyr's Mannox finish for durability and corrosion resistance.
Low Bore Axis Design
The L9-A2 MF's signature characteristic is its extremely low bore axis—the slide sits unusually low in the hand. This geometry reduces muzzle flip and improves shot-to-shot speed compared to higher-axis competitors.
The high grip undercut, extended beavertail, and frame geometry work together to position the shooter's hand as high as possible.
Ergonomics and Grip Design
The grip design represents one of the platform's most praised aspects. Aggressive but comfortable texturing covers the grip surfaces. The undercut trigger guard allows a high grip. The extended beavertail prevents hammer bite while enhancing control.
The interchangeable panels accommodate various hand sizes and preferences. Reviewers frequently describe the ergonomics as excellent—the gun points naturally and fits the hand securely.
Trapezoidal Sight System
Steyr's proprietary triangular front and trapezoidal rear notch sight system provides quick alignment by focusing attention on the front sight.
This unconventional design polarizes users—some appreciate the fast acquisition while others find it odd compared to traditional three-dot systems. Factory options remain limited, and aftermarket replacements prove scarce.
Trigger System
The Trigger Reset System (T.R.S.) provides approximately 4.5-5-pound pull weight with a fairly crisp break and short reset. Minimal pull-weight variation supports consistent shooting. Multiple reviewers compliment the trigger as superior to stock Glock triggers, with quick reset suitable for fast shooting. Users report no short-stroking issues during rapid fire.
