Overview
The Sphinx SDP Compact Alpha is a high-end, Swiss-made 9mm semi-automatic handgun designed for both law enforcement and civilian markets. First released in 2015, the SDP Compact Alpha is a compact version of Sphinx’s renowned SDP series, offering exceptional quality, precision, and reliability.
With a compact 3.6-inch barrel and a weight of 28.5 oz, the SDP Compact Alpha strikes a balance between being maneuverable for concealed carry and maintaining enough heft for excellent recoil control. It is chambered in 9mm Luger, with a 15-round magazine capacity, making it ideal for those seeking a compact pistol with full-size performance.
Strength and Quality
The Sphinx SDP Compact Alpha exemplifies Swiss engineering, delivering a finely crafted handgun. The steel slide and polymer frame construction provide an excellent balance of strength, durability, and weight. The pistol’s precision-machined internals ensure a smooth operation and high reliability.
One of the most notable features of the SDP Compact Alpha is its smooth, crisp trigger pull. The trigger break is short, providing rapid reset times and ensuring faster follow-up shots. The sights are high-quality and easy to align, and the textured grip further improves shooting control.
However, at a premium price, the SDP Compact Alpha’s quality is in line with its cost, positioning it as a luxury handgun rather than a budget or entry-level option.
Safety Features
The Sphinx SDP Compact Alpha comes equipped with several key safety features to ensure safe handling and operation:
- Manual Safety: The pistol features an ambidextrous manual safety that can be engaged to prevent accidental discharge.
- Trigger Safety: Like many modern handguns, the SDP Compact Alpha has a trigger safety to prevent the gun from firing unless the trigger is intentionally pulled.
- Loaded Chamber Indicator: The gun includes a visual loaded chamber indicator, which makes it easier to check the status of the chamber without needing to rack the slide.
Test Results
Accuracy
The Sphinx SDP Compact Alpha provides superb accuracy for its size. During testing, it produced tight groupings at both close and medium ranges. At 7 yards, a group of shots measured around 1.5 inches, while at 15 yards, it expanded slightly to 3 inches, demonstrating consistent precision.
Recoil and Control
The Sphinx SDP Compact Alpha is known for its manageable recoil. Despite its compact design, the pistol’s weight and polymer frame absorb recoil well, allowing for quick follow-up shots. Shooters can maintain a firm grip and control, even during rapid fire, making it an ideal choice for both new and experienced users.
Reliability
Over a 1,000-round endurance test, the SDP Compact Alpha showed outstanding reliability. No malfunctions or failures to feed were experienced, regardless of the ammunition used (FMJ or hollow points). This level of reliability is crucial for those who plan to rely on the gun for personal defense or duty use.
