In my two days of possession of this fine product, I have placed 98 shots with it, using but a singular CO2 cartridge. This facsimile of a firearm looks wonderful, as advertised it is indeed 1:1 weight with the actual firearm it was designed after. There is indeed an under-barrel rail attached, to mine I purchased and attached a NC STAR Green Laser (http://www.airsoftgi.com/product_info.php?products_id=6855) which fits wonderfully. Unfortunately, there is no blowback on this handgun, meaning that it cannot recock itself with each shot. To assist in this manner, a double action functionality was added to the hammer, meaning that whilst the trigger is pulled, the hammer is cocked. However, this begets this otherwise stellar airsoft gun in that much more force is required to pull the trigger, which may very likely throw off your aim as one goes to fire. Overall, this is a wonderful product, and within the criterium in which I have searched for a handgun, I have found the "WG Full Metal Xtreme Special 1911 CO2 Pistol Airsoft Gun" to be peerless.
-Incredibly powerful, accurate, and reliable hardware.
-Incredibly fuel efficient: One CO2 cartridge can provide enough fuel to fire near 100 times.
-Beautiful: Despite the fact that the "wood" is in fact a plastic facsimile (that looks wonderful regardless of material), the firearm looks wonderful, as is undoubtedly observable in the picture included.
-Fully supports under-barrel attachments.
-Inexpensive: I have spent literally double the price on a handgun nowhere near the quality and performance of this product.
-No blowback functionality, which begets the second "con."
-The double action functionality: greatly increases the amount of force required to pull the trigger, resulting in a reduction of accuracy as you shift the focus of your hand from aiming the gun to pulling the trigger.
