Airsoft Pistol Product Details

Green Gas WE M.E.U. 412 Blowback Pistol FPS-390 Airsoft Gun (2 Magazines)

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.

Information About Airsoft Handgun Styles

Find information about airsoft pistols and handguns and how you can use them as extra guns or as primary weapons on the airsoft playing field. A large number of airsoft pistols are fully manufacturer licensed replications of their real gun equivalents and run and look in the same ways while shooting airsoft BBs rather than actual bullets.

There are a few kinds of airsoft sidearms consisting of CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun pistols. Each of these styles of handguns come with benefits and differences connected with them. Finding out about the styles of airsoft sidearms lets you make a decision on which type is right for you and your airsoft game play style.

About CO2 Airsoft Handguns

CO2 airsoft guns are one of the most common and heavy duty types of pistols. These handguns use sealed CO2 gas cylinders to send airsoft BBs out of the handgun barrel.

These kinds of airsoft weapons are excellent for playing airsoft in cooler weather since the pressurized CO2 gas is less sensitive to performance variations with temperature levels. This fact gives CO2 airsoft guns exceptional FPS and shot consistency while playing airsoft in the winter season for instance where other varieties of guns like green gas cease to function or hardly shoot airsoft BBs.

Information About CO2 Gas and CO2 Cartridges

CO2 airsoft sidearms are powered by conventional 12 gram CO2 cartridges. These cartridges resemble a metallic cylinder and store high pressure CO2 gas composed of just one carbon atom and a couple of oxygen atoms, as a result of the molecular formula is “C + O2 “. These atoms are bonded in the following order “O= C =O”. The gas is held in the 12 gram cylinders under extremely high pressure of around ~ 800psi that converts to 55bar.

They come sealed to keep the CO2 gas safely within, but when they are opened (shooting them inside of an airsoft gun breaks the 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 opportunity to do some handgun target practice and use up the rest of the excess gas.

CO2 cartridges can be stored for a while if the cylinders are stored sealed. They come with a manufacturer’s expiry date normally listed on the box or cartridge cylinder, however they can stay pressurized for a long period of time past this date if the cartridge seals are not broken.

Green Gas and Propane Airsoft Handguns

Green gas airsoft handguns function similarly to CO2 pistols, but they do not use CO2 cartridges. Alternatively, they use green gas or propane for propellant to fire the airsoft pellets. The outcome on the airsoft battlefield and green gas sidearm functionality is practically the same as CO2 handguns with the guns shooting up to 300+ feet-per-second (FPS). Shots are quickly fired in semi-automatic or automatic firing modes and can accurately hit targets at very short to mid-range proximities.

The propane is stashed in the pistol’s mag that can usually hold around 15 to 20+ BBs based on the handgun design. A series of valves, rubber gaskets, and seals keep the gas stored in the mag until the pistol’s trigger is squeezed.

When using a green gas sidearm on the airsoft field as a secondary or main gun, bringing extra magazines is recommended for quickly reloading and engaging opponents. Having additional magazines allows you to join in the action throughout firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas pistols are perfect for CQB at airsoft fields considering long guns and full-sized AEGs are normally not approved to be used during indoor gameplay. This is an essential safety regulation because of the close quarters proximity of gamers during shooting engagements and the potential for players to be hurt. While green gas handguns still fire airsoft BBs at about 300 FPS, the shorter handgun barrel assists to keep the joules and energy launching the BB at a decreased level compared to AEGs, sniper rifles, and long guns.

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

There are two various forms of green gas airsoft handguns. To start with there are green gas blowback handguns or GBBs. These guns work like a realistic pistol with the slide “blowing back” and cycling with every shot. The propane triggers the slide to cycle each time when a fresh airsoft BB is loaded into the chamber. The result is really cool, however the GBB guns usually are more expensive and possibly have more parts that can break. The green gas non-blowback airsoft guns use a fixed slide which does not cycle. The non-blowback guns usually cost less than GBBs. Efficiency is around the same between the two kinds of green gas handguns.

About GBB and Green Gas Limits

Due to the fact that the green gas or propane gas is stored in the pistol mag by using rubber o-rings, seals, and gaskets, cold temperatures can influence these seals and allow the stored gas to escape before shooting the handgun. The decrease in pressure can cause the airsoft BBs to just land a few feet (like 10 feet in the cold ) when it would usually shoot 6mm BBs over 100+ feet in warmer weather).

One solution to this problem is to try to keep the GBB pistol magazines warmer by putting them next to a heat source or by your body prior to game play. This can help to heat up the rubber seals and better seal in the green gas. If you really desire to play airsoft with a reliable airsoft handgun in the cold, it may also be worth getting a CO2 version of your preferred handgun. The CO2 cylinders come sealed and perform much better in sub-freezing conditions and while playing in the snow.

About Spring Airsoft Pistols

Spring airsoft handguns are powered by powerful coil springs that launch the BBs out of the pistol barrel. They are typically one shot only. The manual action of reloading, shooting, and cocking spring guns makes the weapon’s fire rate much slower than CO2 and GBB handguns. This makes spring airsoft guns entertaining to use, yet they can be less effective when taking on competitors on the airsoft field with upgraded airsoft guns like auto airsoft AEG assault rifles and CO2, green gas, or GBB airsoft pistols.

Spring sidearms and guns work most effectively in springer wars where participants can solely use related, single shot spring weapons or as a close quarters combat backup gun for CQB buildings and MOUT sites when you can frequently quietly sneak up on other airsoft participants to get a guaranteed one-shot-one-kill. In the latter case, a fast second follow-up shot is not really needed due to the fact that the other opponent is already hit by the first shot and out of the game or headed back to respawn. Take care when fighting numerous adversaries given that the spring airsoft gun only fires as quickly as you can re-chamber an airsoft BB by hand.

About Spring Handgun Efficiency

Spring guns are really reliable under the proper scenarios and airsoft games. Spring guns like pistols can usually shoot accurately up to 120 feet or farther with 0.12 gram BBs but the ability to hit targets reduces rapidly.

Info on AEG Automatic Electric Airsoft Handguns

AEG airsoft sidearms or AEPs (automatic electric pistols) are also a good choice to use as a backup gun on the airsoft field. These automatic electric pistols are commonly powered by mini stick batteries in the gun’s grip. They operate similar to an AEG SMG and use pressured air pumped through electrically cycled pistons and cylinders to shoot airsoft BBs out of the barrel and rapidly.

AEG pistol magazines generally carry about 20 to 30 airsoft BBs. The pistols can fire airsoft BBs up to about 300 FPS using 0.12g airsoft BBs or 200 to 250 FPS with 0.20g airsoft BBs.

AEG Handgun Quality and Efficiency

AEG handgun quality has actually grown substantially recently. The earliest generation guns were a bit questionable and unreliable, but the new designs have most of the deficiencies resolved and make efficient airsoft backup guns. They can be further modded with increased mag storage capacities and by accommodating bigger batteries.

A huge perk of using an AEG handgun is that you have the ability to rewire the adapters to use a bigger battery with higher mAh. Depending on the AEG handgun design, you can gain a large jump in efficiency by using a two cell Lipo battery (2S Lipo) as a replacement for the standard mini battery. Take extra precautions when customizing the elements and wires because you need to take into consideration the voltages, mAh, and loads of the batteries. If you have customization concerns, ask a pro airsoft gun tech at your closest airsoft shop.

What Airsoft Pistol is Right for Me to Play with?

Choosing the right airsoft sidearm for you depends upon how much you can afford to spend, how much you would like to play airsoft with it, and where you hope to play. Look into a GBB handgun or AEG handgun if you have more than one-hundred dollars to invest on your airsoft pistol. These guns are normally the best of the best, have the best build qualities, and are usually a really good airsoft gun to invest in. Look into a CO2 handgun or cheaper GBB handgun if you have around more than $50 but less than $100 to buy a gun. These guns will still finish the job and are pretty tough sidearms. Look for a low end CO2 or spring pistol if you have $50 or less. You can still buy a dependable airsoft handgun to use for the handgun games.
