"I have the green gas version of the gun and I've had it for about a year and the gun is great even though the mag leaks because I dropped the gun(I am left handed and can't find a holdster)

Good gas use
Relatively high gas efficiency
Decent range and fps

Fragial mag (mine hit dirt)

"Realism: Looks, feels, and weighs like the real thing. No Sigma licensing, but there's also no warning information, which gives the gun a clean look. All you get is the KWC badge on either side of the grip. Ejection port is cut out which allows for inspection, removal of jammed BB's, etc. Gun field strips for cleaning and maintenance. Last, but not least, is the full-sized 22 round C02 metal magazine.

Function: Single action, blow back. Blow back is quite forceful and the slide remains open when the last round has been fired.

Accuracy/Reliability: This gun shot a tight group, for the most part, in and around bulls eye from 20 feet. No jams were experienced from initial shooting session. Target acquisition was easy to achieve with the aid of the bold white dot sights.

C02 Consumption: Excellent! Shot 4-20 round magazines from one Crosman C02 cartridge.

Fit and Finish: Barrel is loose. Don't know if that is by design or a design flaw. Orange tip came loose during initial shooting session (removed it and gun looks even more real!). Plastic trigger and safety are causes for minor concern; both could eventually break.

This Sigma replica is a 'can't go wrong' choice if you're new to airsoft and looking for a first gun, or if you're already established and looking to add more to you're collection.

"I got the black version a few months back, and it was an awesome gun. good fps (380-400), accurate to beyond 100 feet, and a 39-round mag that lasted forever and looked cool.
