Comments: The Sig Sauer GSR 1911 is one in a series of CO2-powered replicas made in Taiwan by KWC and distributed world-wide by Cybergun (France). The U.S. importer is Palco Sports. The trademarks on this gun are officially licensed from Sigarms. The GSR 1911 is, itself, a modified copy of the venerable Colt 1911. This all metal replica (even the grip panels are metal) is a good reproduction of the details from the original firearm, including the Weaver-style accessory rail under the dust cover. The only functional parts on the GSR 1911 are the trigger, magazine release, and thumb safety. All the other replica parts (slide, grip safety, sights, slide lock) are non-functional and molded into the frame as a single unit. The trigger has a long hard pull with no distinct breaking point. This very heavy and well-built gun has an authentic feel and decent accuracy for a smooth-bore BB gun.

Performance: Measurements were made on 11/28/08 at a temperature of 72 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using Daisy Avanti BBs (5.5 gr). The highest velocity measured was 407 fps, the lowest was 351 fps (average of the 10-shot string was 377 fps, s = 18). A six shot string fired with open sights using Daisy Avanti BBs grouped at 0.76". Click the thumbnail below to see a larger image. Click here for a description of the measurement methods.


 


 
Right Profile:

 
Left Profile 2: The hammer moves back and forth as the gun is fired, but it is a purely cosmetic effect. The front and rear sights have white dots painted on them.

 
Front View: The molded controls look pretty authentic even though they are non-functional except for the magazine release and thumb safety. The thumb safety can only be operated from the left side of the gun.

 
Right Side Markings: The outer barrel, visible through the "ejection port", is made from plastic.

 
Left Side Markings:

 
Loading BBs: BBs are loaded from the top of the magazine while holding down the spring follower. Release the follower slowly to avoid having BBs spill out the top of the magazine. The gun is provided with a plastic tool to aid in loading the magazine.

 
Loading CO2: The CO2 piercing mechanism is tightened with a 5 mm hex key. The piercing mechanism is not visible once it is tightened.
