Airsoft Pistol Product Details

Green Gas HFC HGA-199 FPS-350 Full Metal Airsoft 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.

How to Choose an Airsoft Pistol

Learn about airsoft pistols and handguns and how you can use them as extra guns or as core weapons on the airsoft playing field. Lots of airsoft handguns are completely manufacturer licensed variations of their real gun counterparts and look and operate in the very same ways while shooting airsoft BBs instead of genuine bullets.

There are a number of kinds of airsoft handguns including CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric pistols. Each of these styles of handguns come with negatives and positives related to them. Learning more about the varieties of airsoft sidearms allows you to choose which type is right for you and your airsoft gameplay style.

CO2 Airsoft Sidearm Details

CO2 airsoft pistols are one of the most common and heavy duty types of pistols. These handguns use pressurized CO2 gas to move airsoft BBs out of the handgun barrel.

These kinds of airsoft guns are great for airsoft games in colder temperatures since the compressed CO2 gas is stored in the sealed cylinders and less prone to FPS decreases with low temperature. This fact offers excellent FPS and shot consistency while playing airsoft in the winter for instance where other styles of handguns like green gas stop working or hardly shoot BBs.

Info About CO2 Gas and CO2 Cartridges

CO2 airsoft guns are powered by typical 12 gram CO2 cartridge cylinders. These cartridges resemble a shiny steel cylinder and contain high-pressure CO2 gas consisting of 1 carbon atom and a pair of oxygen atoms, and so the molecular formula is “C + O2 “. These atoms are bonded in the following alignment “O= C =O”. The gas is kept in the 12 gram cylinders under really high pressure of about ~ 800psi which correlates to 55bar.

They come sealed to keep the CO2 gas safely within, however soon after they are opened (firing them in an airsoft handgun breaks the seal) they will start 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.

CO2 cartridges have a long storage life if they are stored sealed. They are made with the supplier’s expiration date usually marked on the box or cartridge, but they may survive for a very long time past this date if the cartridge seals are not damaged.

Info About Green Gas Airsoft Handguns

Green gas airsoft sidearms function similarly to CO2 guns, however they do not use CO2 cartridges. As an alternative, they use green gas or propane gas for propellant to fire the airsoft BBs. The effect on gameplay and green gas handgun efficiency is just about the same as CO2 handguns with the guns shooting up to 300+ FPS. Shots are rapidly fired in semi-automatic or automatic shooting modes and can hit targets at very short to mid-range proximities.

The green gas is kept in the pistol’s grip within the magazine and can typically hold between 15 to 20+ BBs depending upon the pistol design. A series of valves, rubber stoppers, and o-rings keep the green gas stored in the mag prior to when the pistol’s trigger is pulled. It is a great choice to top off and refill the green gas in the mag each time you load it into the handgun. Pistol-wielding gamers can also bring supplemental bottles of propane gas in the field for refilling magazines between lulls in the battle or in-between missions.

When using a green gas sidearm on the airsoft field as a main or backup gun, extra magazines are strongly recommended for rapidly reloading and getting back into the game. Having additional magazines allows you to reengage in the action in the course of firefights or while sweeping buildings in CQB (close quarters combat) room-to-room combat.

Green gas handguns are ideal for CQB at airsoft fields given that rifles, long guns, and full-sized AEGs are typically not authorized to be used during indoor shooting. This is an essential safety rule due to the close quarters proximity of gamers during the shooting engagements and the potential for players to be hurt. While green gas handguns can still shoot airsoft BBs at around 300 FPS, the shorter pistol barrel helps to keep the joules and energy launching the BB lower compared to AEG airsoft rifles, sniper rifles, and long guns.

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

There are two different varieties of green gas airsoft handguns. To begin with there are green gas blowback handguns or GBBs. These handguns run like a real pistol with the pistol’s slide “blowing back” and moving with every shot. Each time a fresh airsoft BB is chambered, the gas triggers the slide to cycle. This functionality is extremely cool, but the weapons typically are more expensive and likely have more parts to break. The green gas non-blowback airsoft pistols use a fixed slide which does not move. The non-blowback pistols generally cost less than GBBs. Efficiency is about the same when comparing the two types of green gas pistols.

About GBB and Green Gas Limits

Because the green gas or propane is housed in the mag by using rubber seals and gaskets, cold weather can negatively influence these seals and allow the stored gas to escape before shooting. This lack of pressure can make the airsoft BBs to just shoot a few feet (like 10 feet in cold temps ) when the pistol would normally shoot BBs over 100+ foot distances in warmer weather).

One solution to this challenge is to try to keep the GBB pistol magazines warmer by holding them next to a heater or by your body just before the airsoft game play. This can help to warm the seals, gaskets, and valves and better seal in the green gas. It might also be worth getting a CO2 variation of your favorite pistol if you truly want to play airsoft with a reputable airsoft pistol in the cold. The CO2 cylinders come sealed and perform better in sub-freezing temps and while playing in the snow.

Info on Spring Airsoft Sidearms

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

Spring airsoft guns perform most effectively in springer battles where airsoft players can only use similar, single shot spring weapons or as a close quarters backup gun for CQB environments when you can frequently sneak up to other airsoft opponents to get a guaranteed one-shot-one-kill. In the latter scenario, a rapid second follow-up shot isn’t called for due to the fact that the other opponent is already struck and out of the gameplay or heading back to respawn. When engaging multiple opponents because the springer only shoots as quick as you can re-chamber an airsoft BB by hand, be cautious.

About Spring Pistol Efficiency

Spring pistols are very reliable under the proper scenarios and airsoft games. Their FPS typically chronos at around 250 FPS to 300 FPS with lighter 0.12g airsoft BBs. These handguns normally fire the lighter weight airsoft BBs since the coiled springs are less effective than other styles of airsoft guns. Spring guns can normally be accurate at up to 120 feet or more with 0.12g BBs but the ability to hit targets diminishes rapidly. Using standard 0.20g weight airsoft BBs, you will probably have a range of around 60 to 80 feet or less with increased target accuracy.

AEG Automatic Electric Airsoft Sidearms

AEG airsoft pistols or AEPs (automatic electric pistols) are also an option to bring into the field as a backup gun on the airsoft field. These automatic electric handguns are often powered by mini stick batteries in the gun’s grip. They work similar to an AEG SMG and use pressurized air with electrically cycled cylinders, pistons, and gearboxes to propel airsoft BBs out of the barrel and rapidly.

AEG handgun magazines usually carry about 20 to 30 airsoft BBs. The handguns can fire airsoft BBs up to around 300 FPS using 0.12 gram airsoft BBs or 200 to 250 FPS with 0.20g airsoft BBs.

AEG Pistol Quality and Efficiency

AEG pistol quality has increased substantially over the last few years. The initial generation AEP guns were a bit questionable and unreliable, but the newer versions have the deficiencies worked out and make reliable airsoft backup weapons. They can be further upgraded with increased magazine capacities along with accommodating more powerful batteries.

A large advantage of carrying an AEG handgun is that you have the ability to rewire the adapters to use a bigger battery. Depending on the AEG pistol type, you can gain a huge increase in efficiency by adopting a 2 cell Lipo battery (2S Lipo) rather than the stock AEP battery.

What Airsoft Sidearm is Best for Me to Buy?

If you have over $100 to use to buy your airsoft handgun, you may want to consider a GBB pistol or AEG pistol. If you have between $50 to $100 to shell out, look at a good quality CO2 pistol or more affordable GBB handgun. You can still get a durable airsoft handgun by checking out cheaper pistols and by shopping for used pistols if you need to save money.
