Airsoft Pistol Product Details

Green Gas WE M1911 409 Blowback Pistol FPS-400 Airsoft Gun

Airsoft Pistol Product Features

This is a Green Gas Airsoft Pistol which means that it uses Green Gas as a propellant. It shoots hard and fast and is extremely lifelike. One feature many Green Gas Airsoft Guns have is blowback, meaning that as the BB is propelled forward the slide thrusts backward mimicking the kick of a real gun! This Green Gas Airsoft Pistol doesn’t require any pumping just simply point and shoot. This is a high end Green Gas Airsoft gun. Please only use .20 gram high quality BBs with this item in order to keep it in working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. You must be 18 years of age or older to purchase this Airsoft gun. You will need to purchase Green Gas for this gun separately.

Airsoft Pistol Style Additional Information

Find out about airsoft pistols and sidearms and how you can use them as backup weapons or as main weapons on the airsoft playing field. Getting the best handgun and practicing with it can make all the difference in improving your shots. Sidearms, by nature, are reduced range airsoft weapons. They are usually constructed after real-world sidearms or imitations of actual pistols. A large number of airsoft sidearms are completely certified adaptations of their genuine handgun equivalents. These airsoft guns can visually appear and function (without shooting bullets) in the same ways identically to the real guns they are modeled around while firing airsoft BBs instead of real-world bullets.

There are several varieties of airsoft sidearms including CO2, green gas or propane (blowback and non-blowback), spring powered, and AEG automatic electric gun sidearms. Each of these types of sidearms has negatives and positives associated with them. Learning about the types of airsoft handguns allows you to figure out which type is right for you and your airsoft play style.

CO2 Airsoft Sidearm Details

CO2 airsoft handguns are among the most heavy duty and standard kinds of handguns. They are all-weather pistols and operate well in lots of kinds of weather, varying temperatures, and climates. These sidearms use pressurized CO2 gas to launch airsoft BBs down the gun barrel. The CO2 cartridge is normally held in the handgun’s magazine.

These types of airsoft guns are excellent for playing airsoft in cold and snowy temperatures due to the fact that the high pressure CO2 gas is stored in the sealed cylinders and less sensitive to performance decreases with temperature levels. This offers excellent FPS and shot consistency while playing airsoft in the winter for example where other types of airsoft pistols like green gas cease to operate or hardly shoot BBs.

Additional Info About CO2 Gas and CO2 Cylinders

CO2 airsoft pistols are powered by common 12 gram CO2 cartridges. These cartridges resemble a shiny metallic cylinder and contain high-pressure CO2 gas consisting of a single carbon atom and a couple of oxygen atoms for this reason the molecular formula is “C + O2”.

They come sealed to keep the CO2 gas safely inside, however soon after they are opened (shooting them in an airsoft weapon breaks the cartridge seal) they will begin to lose pressure if they are left unused. If the airsoft games end and you still have CO2 gas left, use the chance to do some pistol target practice and use up the rest of the additional gas.

If they are kept sealed, CO2 cartridges can be stored for a while. They have a manufacturer’s best used by date usually marked on the box or cartridge, however they will probably survive for a long period past this date if the cartridge seal is not damaged.

Details About Green Gas Airsoft Sidearms

Green gas airsoft sidearms are similar to CO2 handguns, however they do not use CO2 cartridges. Instead, they use green gas or propane for propellant to fire 6mm airsoft BBs. The operational impact on the battlefield and green gas sidearm performance is virtually the same as CO2 pistols with the weapons shooting up to about 300+ FPS. Shots are rapidly fired in semi-automatic or automatic shooting modes and precisely hit targets at shorter to mid-range proximities.

The propane is stored in the handgun’s magazine which can frequently hold around 15 to 20+ BBs depending on the pistol type. A series of valves, rubberized gaskets, and silicone o-rings keep the gas stored in the mag up until the handgun’s trigger is squeezed.

When running a green gas pistol on the airsoft field as a main or backup weapon, additional magazines are recommended for rapidly reloading and getting back into the game. Having additional mags on-hand helps you reengage in the action during firefights or while clearing structures in CQB (close quarters combat) room-to-room combat.

Green gas pistols are suitable for CQB at airsoft fields considering that rifles, long guns, and full-sized AEGs are normally not authorized to be used during indoor shooting. This is an essential safety rule because of the close range distance of airsoft players during the shooting engagements and potential for players to get hurt. While green gas pistols can still fire airsoft BBs at about 300 FPS, the shorter handgun barrel helps to keep the joules and energy moving the BB lower compared to AEGs, airsoft rifles, sniper rifles, and long guns.

Thinking About Green Gas Blowback (GBB) VS Green Gas Non-blowback

There are 2 various types of green gas airsoft handguns. There are green gas blowback handguns or GBBs. The green gas non-blowback airsoft pistols use a fixed slide which does not move.

About GBB and Green Gas Issues

While green gas normally can be used very well on the airsoft field, it does have restrictions. When they are used during the winter airsoft games in the snow or in cold temperatures (such as under 32 degrees F). Since the green gas or propane is kept in the weapon’s magazine by rubber seals, o-rings, and gaskets, low temperatures can impair these seals and trigger the stored gas to seep out prior to shooting airsoft BBs. The depressurized gas can make the airsoft BBs to just shoot several feet (like 10 feet in cold temps ) when the gun would usually shoot BBs over 100+ foot ranges in warmer temperatures).

One solution to this problem is to make the GBB pistol mags warmer by positioning them next to your body or by a heater just before the airsoft game play. If you truly want to play with a trustworthy airsoft handgun in the cold, it may also be worth getting a CO2 variation of your preferred pistol.

Spring Airsoft Sidearms

Spring airsoft guns are powered by strong coil springs that launch the BBs out of the gun’s barrel. The manual action of cocking, shooting, and reloading spring guns makes the fire rate much slower than CO2 and GBB airsoft guns.

Spring guns perform best in springer wars where airsoft players can only use related, single shot spring weapons or as a close quarters backup gun for CQB environments when you can usually surprise other airsoft game players to get a guaranteed one-shot-one-kill. In the latter situation, a quick second follow-up shot isn’t needed given that the other player is now hit by the first shot and out of the game or headed back to respawn. When engaging a number of foes considering that the spring gun only shoots as fast as you can re-chamber an airsoft BB manually, be cautious.

About Spring Handgun Performance

Spring pistols are very reliable under the appropriate game circumstances. Their FPS normally chronos at about 250 FPS to 300 FPS with lighter weight 0.12 gram airsoft BBs. These handguns usually fire the lighter weight airsoft BBs due to the fact that the springs are less effective than other types of airsoft guns like rifles. Spring guns can typically engage targets at ranges of up to 120 feet or more with 0.12g BBs however the ability to engage targets reduces rapidly. Shooting basic 0.20 gram weight airsoft BBs, you will very likely have a decreased range of about 60 to 80 feet or less with enhanced target accuracy.

AEG Automatic Electric Airsoft Handgun Info

AEG airsoft pistols or AEPs (automatic electric pistols) are also a good choice to bring as a backup gun on the airsoft field. These automatic electric pistols are typically powered by mini stick batteries in the pistol’s handle. They function similar to an AEG gun and use pressurized air forced through electrically cycled cylinders, pistons, and gearboxes to shoot airsoft BBs out of the barrel and rapidly.

AEG pistol mags generally can hold about 20 to 30 airsoft BBs. The pistols can fire airsoft BBs as high as about 300 FPS when loaded with 0.12 gram airsoft BBs or 200 to 250 FPS using 0.20 gram airsoft BBs. The electrically powered gearbox system can shoot around 700+ BBs per minute which depends if you have enough magazines to reload with and the battery lasts that long. These AEP handguns can effectively fire airsoft BBs at around 150 foot ranges.

AEG Pistol Quality and Performance

AEG pistol quality has actually risen substantially in the last few years. The initial generations were a little bit sketchy and unreliable, however the new models have most of the deficiencies resolved and make reliable airsoft backup weapons. They can be modified with maximized magazine storage capacities together with accommodating bigger batteries.

A substantial perk of carrying an AEG pistol is that you have the capability to rewire the adapters to use an increased capacity battery with longer life. Depending upon the AEG pistol design, you are able to gain a substantial output in performance by using a 2 cell Lipo battery (2S Lipo) as a replacement for the standard battery. Be careful when adjusting the components and the gun’s wires since you have to think about the volts, mAh, and loads of the batteries. Ask a qualified airsoft gun technician at your nearest airsoft store if you have customization concerns.

What Airsoft Pistol is Best for Me?

If you have $100 or more to spend on your airsoft handgun, check out a GBB handgun or AEG pistol. If you have in-between fifty to one-hundred dollars to buy a gun, review a CO2 pistol or more affordable GBB handgun. You can still look for a durable airsoft pistol by checking out cheaper pistols and by shopping for used pistols if you need to save money.
