Comments: This gun comes as part of a kit that includes a 4" barrel, an 8" barrel, and Crosman red-dot sight (I have also added a 6" barrel to the set). This gun represents an update of the original Model 357-6. However, the fit and finish of the 357GW  are not as good as they were on the earlier 357-6. The grips are made to look like rubber, but are actually plastic. They have a tendency to loosen with use. The accuracy of this gun with the 4" barrel installed is only fair, but with the 8" barrel it is excellent. While the measured muzzle velocities were very consistent, they were far below the advertised velocities.

Pyramyd Air Report on Crosman 357GW.

Performance: Measurements were made on 8/13/06 at a temperature of 77 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using Crosman Premier Super Match pellets (7.9 gr). With the 4" barrel, the highest velocity measured was 326 fps, the lowest was 319 fps (average of the 10-shot string was 322 fps). A six shot string fired with open sights grouped at 0.71". With the 8" barrel, the highest velocity measured was 377 fps, the lowest was 320 fps (average of the 10-shot string was 345 fps). A six shot string fired with open sights grouped at 0.24".

Loading Pellets: A weak point of this design is the latch that holds the barrel closed. This loosens over time resulting in a floppy barrel and a decrease in accuracy.

Loading CO2: Both grips must be removed to install the CO2 bulb. The grips, when installed, conceal the bulb piercing screw. Having to remove both grips makes changing CO2 cylinders a real pain.
