About the Gun

Built on the patented modular steel frame with polymer grip, the Eagle delivers the traditional features of a 1911 and allows the added benefit of high capacity magazines. The frame design preserves the original 1911 angle of the grip in relation to the slide. The essential design element for high capacity, the polymer grip, allows for double stack magazines without over-sizing the circumference of the grip, which remains comparatively the same as the circumference of a 1911. The Eagle has a classic scalloped slide with front and rear cocking serrations, dovetail front sight and adjustable rear sight. The Eagle comes standard with features such as a stainless steel hi-ride grip safety and stainless steel ambi-thumb safety.

Analysis

This 9x21 mm pistol demonstrates notable precision, thanks to its well-engineered barrel and consistent lockup, making it a solid choice for target shooting or competition. The ergonomic design offers a comfortable grip, accommodating a wide range of hand sizes, while the balance aids in steady handling during extended sessions. Reliability is a strong point, with the firearm cycling smoothly under various conditions when properly maintained. However, upkeep can be demanding, as it requires meticulous cleaning to prevent malfunctions due to its tight tolerances. Availability of replacement parts may pose a challenge, potentially frustrating owners in need of repairs. The trigger pull is crisp, averaging around 4.5 pounds in single action, which enhances control. Felt recoil is moderate for the caliber, manageable for most shooters with proper technique, though less experienced users might find it somewhat sharp during rapid fire.
