Airsoft Pistol Product Details

Green Gas WE V4 Hi-Capa Pistol FPS-400 Full Metal, Blowback 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.

How to Pick an Airsoft Pistol

Find information about airsoft sidearms, pistols, and handguns and how you can use them as secondary weapons or as primary weapons on the airsoft playing field. A large number of airsoft pistols are completely manufacturer licensed versions of their genuine firearm equivalents and operate and appear in the very same ways while shooting airsoft BBs rather than authentic bullets.

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

Details About CO2 Airsoft Handguns

CO2 airsoft guns are one of the most dependable and standard types of pistols. These pistols use high pressure CO2 gas to move airsoft BBs out of the gun barrel.

These types of airsoft pistols are great for playing airsoft in cooler weather conditions due to the fact that the pressurized CO2 gas is stored in the sealed cylinders and less susceptible to performance decreases by low temperature. This fact gives CO2 airsoft guns very good FPS and shot consistency while playing airsoft in the cold for instance where other styles of airsoft pistols like green gas stuffer from low performance or barely shoot airsoft BBs.

Information About CO2 Gas and CO2 Cartridges

CO2 airsoft pistols are powered by standard 12 gram CO2 cartridges. These cartridges look like a shiny cylinder and store high-pressure CO2 gas consisting of one carbon atom and a pair of oxygen atoms for this reason the molecular formula is “C + O2”.

They come sealed to keep the CO2 gas safely inside, however when they are opened (firing them in an airsoft handgun breaks the cartridge seal) they will start to lose pressure if they are left unused. If the airsoft matches 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 have a long storage life. They come with the maker’s expiration date typically printed on the package or cylinder, but they will likely last for a very long period of time past this date if the cartridge seals are not punctured.

Green Gas Airsoft Sidearm Information

Green gas airsoft pistols are comparable to CO2 pistols, but they use propane gas instead of CO2 cartridges. The operational impact on the airsoft battlefield and green gas weapon efficiency is virtually the same as CO2 handguns with the weapons shooting up to 300+ FPS.

The green gas is stored in the pistol’s magazine which can commonly hold between 15 to 20+ airsoft BBs depending on the handgun design. A series of valves, rubber gaskets, and silicone o-rings keep the gas stored in the mag until the handgun’s trigger is pulled.

When bringing a green gas sidearm on the airsoft field or arena as a backup or primary gun, extra mags are encouraged for rapidly reloading. Having extra mags on-hand helps you reengage in the action in the course of firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas handguns are ideal for CQB at airsoft fields because rifles and full-sized AEGs are normally not allowed to be used during indoor gameplay. This is a safety standard due to the close quarters distance of players during the shooting engagements. While green gas handguns still fire airsoft BBs at around 300 FPS, the shorter pistol barrel assists to keep the joules and energy moving the BB lower compared to AEG airsoft rifles, sniper rifles, and long guns.

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

There are 2 different kinds of green gas airsoft handguns. There are green gas blowback handguns or GBBs. The green gas non-blowback airsoft pistols have a fixed slide which does not move.

About GBB and Green Gas Limitations

Due to the fact that the green gas or propane is housed in the pistol mag using rubber o-rings, seals, and silicone gaskets, the cold can negatively impact these seals and cause the gas to escape prior to shooting. The lack of pressure can cause the airsoft BBs to merely land a couple of feet away (like 10 feet in cold temps ) when the GBB handgun would usually shoot airsoft BBs over 100+ foot distances in warmer temperatures).

One option to this problem is to make the GBB handgun mags warmer by placing them next to your body just before the airsoft game play starts. If you truly need to play with a trustworthy airsoft handgun in the cold weather, it may additionally be worth getting a CO2 style of your favorite handgun.

About Spring Airsoft Pistols

Spring airsoft sidearms are powered by powerful springs with irregular pitches that launch the airsoft BBs down the handgun barrel. They are typically one shot only. The manual action of cocking, shooting, and reloading spring handguns makes the weapon’s fire rate much slower than CO2 and GBB pistols. When confronting rivals on the airsoft field with enhanced guns like automatic airsoft AEG assault rifles, sniper rifles, and CO2, green gas, or GBB airsoft handguns, this can make spring guns entertaining to use, however less effective.

Spring handguns perform most effectively in springer battles where game players can exclusively use similar, single shot spring guns or as an alternative weapon for CQB environments when you can usually sneak up to other airsoft participants to get a guaranteed one-shot-one-kill. In the latter situation, a quick 2nd followup shot isn’t really needed since the other opponent is already hit by the airsoft BB and out of the game play or headed back to respawn. When engaging several airsoft players since the springer just shoots as quick as you can re-chamber an airsoft BB manually, be cautious.

About Spring Handgun Performance

Spring guns are really effective under the correct conditions during airsoft games. Spring guns can often fire up to 120 feet or more with 0.12 gram BBs but the ability to hit targets reduces rapidly.

AEG Automatic Electric Airsoft Handguns

AEG airsoft handguns or AEPs (automatic electric pistols) are definitely a viable option to use as a backup gun on the airsoft field. These automatic electric handguns are typically powered by mini stick batteries in the weapon’s butt. They operate similar to an AEG rifle and use pressured air forced through electrically cycled pistons, gearboxes, and cylinders to shoot airsoft BBs quickly and rapidly.

AEG pistol magazines usually carry about 20 to 30 airsoft BBs. The pistols can fire airsoft BBs up to around 300 FPS using 0.12g airsoft BBs or around 200 to 250 FPS when loaded with 0.20 gram airsoft BBs. The electric battery powered gearbox system can shoot around 700+ BBs per minute which depends on if you have enough spare magazines to maintain the ammo supply and the battery lasts that long. These AEP handguns can accurately fire airsoft BBs at about 150 foot ranges.

AEG Pistol Quality and Efficiency

AEG pistol quality has actually risen considerably in the last few years. The earliest gen guns were a little bit sketchy and undependable, but the more recent designs have most of the issues worked out and make effective airsoft backup weapons. They can be further modified with maximized mag storage capacities along with accommodating larger batteries.

A substantial advantage of using an AEG handgun is that you have the ability to rewire the connectors to use a more substantial battery. Depending on the AEG handgun style, you can gain a substantial increase in performance by adopting a 2 cell Lipo battery (2S Lipo) instead of the stock AEP battery.

Which Airsoft Handgun is Best for Me to Buy?

Picking out the right airsoft sidearm for you depends on how much you want to spend, how much you desire to play airsoft using it, and where you decide to play. Check out a green gas blowback pistol or AEG handgun if you have more than $100 to invest on your airsoft pistol. These kinds of guns are typically the top of the line, have the greatest efficiency, and are usually a good airsoft gun to invest in. If you have about fifty to one-hundred dollars to spend on upgrading your airsoft arsenal, look at a CO2 pistol or a cheaper green gas blowback pistol. Mid-tier guns like these will still work well and can be pretty tough sidearms. If you have less than fifty dollars, consider a lower end CO2 or springer handgun. You can still get a well-built airsoft pistol to use for the pistol airsoft guns.
