Airsoft Pistol Product Details

Green Gas HFC HG-131B FPS-350 Airsoft Revolver Pistol

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 Handgun Variety Information

Learn about airsoft sidearms, pistols, and handguns and how you can use them as extra weapons or as main weapons on the airsoft playing field. Numerous airsoft handguns are completely manufactured and licensed models of their actual pistol counterparts and look and run in the exact same ways while shooting airsoft BBs rather than actual bullets.

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

Details About CO2 Airsoft Sidearms

CO2 airsoft sidearms are one of the most heavy duty and typical styles of pistols. They are all-season, all-weather weapons and work well in lots of types of weather, temperatures, and climates. These pistols use high pressure CO2 gas to send airsoft BBs down the gun barrel. The CO2 cartridge stores the gas within the cylinder and is normally stored in the gun’s magazine inside the handle.

These forms of airsoft handguns are good for airsoft games in cold temperatures considering that the high pressure CO2 gas is less sensitive to performance variations caused by temperature levels. This provides exceptional FPS and shot consistency while playing airsoft in the winter months for instance where other styles of sidearms like green gas cease to work or hardly fire airsoft BBs.

Additional Info About CO2 Gas and CO2 Cylinders

CO2 airsoft guns are powered by basic 12 gram CO2 cartridges. These cartridges resemble a metallic cylinder and store high pressured CO2 gas made up of 1 carbon atom and 2 oxygen atoms, hence the molecular formula comes out to be “C + O2 “. These atoms are connected in the following alignment “O= C =O”. The gas is kept in the 12 gram cylinders under really high pressure of near ~ 800psi that converts to 55bar.

The CO2 cartridges cannot be used multiple times and you can commonly purchase them in bundles of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to retain the CO2 gas securely within, once they are punctured (shooting them in an airsoft handgun breaks the seal) the cartridges will start to lose pressure if they are not used up. You must try to expend the entire CO2 cartridge the same day you open the seal. If the airsoft matches end and you still have CO2 gas left, use the opportunity to do some pistol accuracy and target practice and use up the remainder of the surplus gas. There is no gas level sign on the cartridge so you have to shoot until the gun stops firing airsoft BBs.

CO2 cartridges have a long storage life if the cylinders are stored sealed. They have a supplier’s use by date typically noted on the package or cartridge cylinder, however they may survive for an extended period past this date if the cartridge seal is not damaged.

Info About Green Gas Airsoft Pistols

Green gas airsoft sidearms resemble CO2 pistols, however they do not use CO2 cartridges. Instead, they use green gas or propane for propellant to fire the airsoft pellets. The operational impact on gameplay and green gas pistol efficiency is almost the same as CO2 pistols with the guns shooting up to about 300+ feet per second (FPS). Shots are efficiently fired in semi-automatic or fully-automatic firing modes and can accurately hit targets at very short to mid-range proximities.

The green gas is kept in the handgun’s airsoft magazine which can normally hold around 15 to 20+ airsoft BBs based on the handgun model. A series of valves, rubberized gaskets, and o-rings keep the gas pressurized in the magazine before the handgun’s trigger is squeezed.

When bringing a green gas sidearm on the airsoft field or arena as a primary or backup weapon, bringing additional magazines is highly recommended for quickly reloading and engaging the op force. Having extra magazines helps you re-engage in the action during firefights or while sweeping buildings in CQB (close quarters combat) room-to-room fighting.

Green gas handguns are suitable for CQB at airsoft fields considering rifles, long guns, and full-sized AEGs are normally not approved to be used for indoor engagements. This is an essential safety standard due to the close range distance of gamers during the shooting engagements. While green gas handguns can still shoot airsoft BBs at about 300 FPS, the short handgun barrel assists to keep the joules and energy shooting the BB at a lower level compared to airsoft rifles, sniper rifles, and other long guns.

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

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

About GBB and Green Gas Issues

Since the green gas or propane gas is stored in the magazine by using rubber o-rings, seals, and gaskets, cold temperatures can negatively impact these seals and allow the gas to leak out prior to shooting. The lack of pressure can cause the airsoft BBs to merely land a number of feet (like 10 feet in cold weather ) when the green gas pistol would usually shoot BBs over 100+ feet in warmer weather conditions).

One fix for this issue is to try to keep the GBB handgun magazines warmer by holding them inside your jacket next to your body just before the game play. This can help to warm up the seals, gaskets, and valves and help to seal in the green gas. It may also be worth buying a CO2 variation of your preferred handgun if you actually want to play with a reputable airsoft pistol in the cold. The CO2 cylinders come sealed and the gun shoots far better in sub-freezing conditions and while playing in the snow.

Spring Airsoft Handguns

Spring airsoft pistols are powered by powerful coil springs that fire the BBs out of the gun’s barrel. The manual functions of shooting, cocking, and reloading spring pistols makes the fire rate much slower than CO2, green gas, and GBB handguns.

Spring sidearms and guns work most effectively in springer battles where participants can exclusively use comparable, single shot spring guns or as a transitional backup weapon for CQB buildings and MOUT sites when you can often surprise other airsoft participants to get a guaranteed one-shot-one-kill. In the latter situation, a quick 2nd follow-up shot will not be called for due to the fact that the other player is now hit by the first BB and out of the gameplay or going back to respawn. When engaging multiple opponents considering that the gun only fires as fast as you can re-chamber an airsoft BB manually, be cautious.

About Spring Pistol Performance

Spring guns are extremely useful under the proper situations. Spring handguns can normally fire up to 120 feet or more with 0.12g BBs but the ability to hit targets decreases quickly.

AEG Automatic Electric Airsoft Pistols

AEG airsoft handguns or AEPs (automatic electric pistols) are also an option to carry as a backup gun on the airsoft field. These automatic electric pistols are often powered by mini stick batteries in the gun’s grip. They function similar to an AEG gun and use pressurized air with electrically cycled pistons, cylinders, and gearboxes to shoot airsoft BBs quickly and very quickly at that.

AEG pistol mags typically store about 20 to 30 airsoft BBs. The handguns can fire airsoft BBs right up to about 300 FPS using 0.12 gram airsoft BBs or about 200 to 250 FPS when loaded with 0.20 gram airsoft BBs. The electrical gearbox system can shoot around 700+ BBs per minute which is estimated if you have enough magazines to reload and the battery holds out that long. These handguns can precisely shoot airsoft BBs at about 150 foot ranges.

AEG Handgun Quality and Performance

AEG pistol quality has actually grown substantially in the last few years. The earliest gen AEP guns were a little bit undependable and sketchy, but the newer versions have most of the problems resolved and make efficient airsoft secondary weapons. They can be further upgraded with increased magazine capacities and also accommodating bigger batteries.

A substantial advantage of carrying an AEG handgun is that you have the power to rewire the battery connections to use a larger capacity battery. Depending on the AEG pistol design, you can gain a sizable increase in performance by using a 2 cell Lipo battery (like an 2S Lipo) as an alternative for the stock battery.

Which Airsoft Handgun is Right for Me to Buy?

If you have over $100 to use to buy your airsoft handgun, evaluate a GBB pistol or AEG handgun. If you have around $50 to $100 to invest, evaluate a CO2 pistol or cheaper GBB pistol. If you have less than fifty dollars, you can still choose a durable airsoft handgun to use for the handgun games by checking out lower end pistols and by trading with other players on the used gun market.
