Trigger Characteristics: The trigger pull of the Sig Sauer GSR Sigarms demands a moderate to significant effort. It is heavier than some triggers, likely because of its distinctive 1911-style design.

Shooting Precision: The pistol demonstrates decent precision, producing a 2.5-inch group at 20 feet from a standing position, with shots landing slightly to the left and high. Accuracy improved with familiarity with the trigger pull. Initial chronograph tests showed speeds exceeding the advertised 397 fps, stabilizing around 370 fps, with an average of 422 fps over eight shots using a fresh CO2 cartridge.

Construction Quality: The Cybergun GSR is well-constructed, primarily of metal, with exceptions including the hammer, trigger, magazine release, slide catch, and outer barrel. The slide, frame, magazine, and grips are metal, with a high-quality finish. The air pistol operates reliably without malfunctions.

Authenticity and Realism: The Cybergun Sig Sauer GSR closely replicates the look, weight, and feel of the real GSR Sigarms, featuring a 1911-style trigger and authentic slide markings. Despite lacking a single-action trigger and functional slide, it remains a convincing replica.

Having purchased the Cybergun Sig Sauer GSR Sigarms along with the Cybergun Jericho 941 and Sig Sauer SP2022, I found the GSR to be the most robust due to its metal build. This budget-friendly BB pistol offers excellent value, providing a highly accurate replica of the original GSR Sigarms. For 1911 enthusiasts seeking an affordable airgun, the Cybergun GSR is an outstanding choice, offering significant weight, a metal magazine, and a genuine 1911 trigger experience.
