Airsoft Pistol Product Details

Green Gas HFC M9 121 Pistol FPS-360 Non-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.

Airsoft Handgun Style Details

Learn about airsoft pistols and handguns and how you can use them as extra weapons or as main weapons on the airsoft playing field. A large number of airsoft handguns are completely manufacturer licensed variations of their genuine weapon equivalents and look and operate in the same ways while shooting airsoft BBs rather than real bullets.

There are a variety of airsoft handguns consisting of CO2, green gas or propane (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these styles of sidearms have negatives and positives related to them. Learning about the styles of airsoft handguns allows you to decide which type is right for you and your airsoft play style.

Details About CO2 Airsoft Pistols

CO2 airsoft handguns are one of the most typical and tough types of handguns. These pistols use CO2 stored in small cylinders to send airsoft BBs out of the handgun barrel.

These styles of airsoft pistols are good choices for playing airsoft in cooler temperatures because the compressed CO2 gas is less susceptible to FPS decreases with temperature levels. This fact gives CO2 airsoft guns very good FPS and shot consistency while playing airsoft in the winter for instance where other styles of pistols like green gas stuffer from low performance or hardly shoot BBs.

Info About CO2 Gas and CO2 Cartridge Cylinders

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

The CO2 cylinders cannot be used multiple times and you can normally purchase them in bundles of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to retain the CO2 gas safely and securely inside, once they are opened (shooting them inside of an airsoft gun breaks the seal) the cartridges will begin to lose pressure if they are not used up. You should try to deplete the entire CO2 cartridge the exact same day you open the seal. If the airsoft games end and you still have CO2 gas leftover, use the opportunity to do some handgun accuracy and target practice and expend the rest of the excess gas. There is no gas level guide on the cartridge so you need to shoot until the weapon stops firing BBs.

CO2 cartridges can be stored for a while if the cylinders are kept sealed. They are made with a maker’s expiration date normally printed on the package or cartridge, however, they will likely stay pressurized for an extended time past this date if the cartridge seals are not punctured.

Info About Green Gas Airsoft Sidearms

Green gas airsoft sidearms resemble CO2 pistols, however they do not use CO2 cartridges. Rather, they use green gas or propane gas for propellant to shoot 6mm airsoft BBs. The effect on game play and green gas sidearm operation is almost the same as CO2 handguns with the weapons shooting up to about 300+ feet per second (FPS). Shots are quickly fired in semi-automatic or automatic firing modes and can hit targets at short to mid-range ranges.

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

When carrying a green gas pistol on the airsoft field or arena as a main or backup gun, extra pistol mags are suggested for rapidly reloading. Having additional mags on-hand allows you to re engage in the action during firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas pistols are excellent for CQB at airsoft fields given that rifles, long guns, and full-sized AEGs are generally not authorized to be used for indoor gameplay. This is a safety standard due to the close range distance of players during shooting engagements and the potential for players to be injured. While green gas pistols still fire airsoft BBs at around 300 FPS, the shorter handgun barrel helps to keep the joules and energy propelling the BB lower compared to AEG airsoft rifles, sniper rifles, and other long guns.

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

There are two various styles of green gas airsoft handguns. 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 Limits

Since the green gas or propane gas is stored in the pistol mag by using rubber seals, o-rings, and silicone gaskets, cold weather can negatively affect these seals and allow the gas to leak out before shooting. The decrease in pressure can make the airsoft BBs to only shoot a number of feet away (like 10 feet in cold temps ) when the green gas handgun would typically shoot BBs over 100+ foot distances in warmer weather).

One solution to this problem is to make the GBB handgun mags warmer by holding them next to a heater or by your body just before the game play. This can help to warm up the seals and valves and better seal in the green gas. It might also be worth getting a CO2 version of your preferred handgun if you actually prefer to play with a trustworthy airsoft handgun in the cold. The CO2 cartridges come sealed and the gun shoots much better in sub-freezing conditions and while playing in the snow.

Details About Spring Airsoft Handguns

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

Spring pistols perform best in springer wars where players can only use related, single shot spring handguns or as a close quarters combat weapon for CQB settings when you can often surprise other airsoft opponents to get a guaranteed one-shot-one-kill. In the latter case, a quick 2nd followup shot isn’t called for since the other person is now hit by the first BB and out of the game play or heading back to respawn. When engaging several rivals given that the springer simply shoots as quick as you can re-chamber an airsoft BB manually, be careful.

About Spring Pistol Effectiveness

Spring pistols are really useful under the most ideal situations. Spring pistols can normally shoot accurately up to 120 feet or more with 0.12 gram BBs but the ability to engage targets reduces rapidly.

AEG Automatic Electric Airsoft Handgun Facts

AEG airsoft pistols or AEPs (automatic electric pistols) are also a viable option to bring into the field as a secondary weapon on the airsoft field. These automatic electric pistols are normally powered by mini stick batteries in the pistol’s butt. They work similar to an AEG gun and use compressed air with electrically cycled pistons and cylinders to propel airsoft BBs out of the barrel and very quickly at that.

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

AEG Handgun Quality and Performance

AEG handgun quality has risen substantially in the last few years. The early gen AEP guns were a little bit questionable and unreliable, however the new models have most of the problems resolved and make effective airsoft secondary guns. They can be further modified with increased magazine storage capacities and by accommodating more powerful batteries.

A large benefit of carrying an AEG handgun is that you have the capability to rewire the battery connectors to use a larger capacity battery. Depending on the AEG handgun type, you can gain a sizable jump in functionality by adopting a 2 cell Lipo battery (2S Lipo) as a replacement for the stock mini battery.

What Airsoft Pistol is Best for Me?

Picking the best airsoft handgun for you depends on your budget, how often you intend to play airsoft with it, and where you decide to play. Look into a green gas blowback handgun or AEP handgun if you have more than $100 to invest on your airsoft handgun. These kinds of handguns are typically the best of the best, have good efficiency, and are usually a great airsoft gun to invest in. Look at a CO2 pistol or less costly GBB pistol if you have about more than fifty but less than one-hundred dollars to put into an airsoft gun purchase. Middle of the road guns like these will still be fun to play with and can be durable sidearms. Look for a lower end CO2 or spring pistol if you have less than $50. You can still buy a durable airsoft pistol to use for the handgun games.
