Information on Airsoft Handgun Styles

Learn about airsoft pistols and handguns and how you can use them as backup weapons or as primary weapons on the airsoft playing field. Getting the best sidearm and practicing with it can be a game changer in hitting your shots. Pistols, by nature, are shorter range airsoft weapons. They are most often manufactured after genuine pistols or replicas of genuine pistols. Lots of airsoft handguns are fully licensed models of their real weapon counterparts. These airsoft guns can function (without shooting bullets) in the same ways and visually look almost identically to the real guns they are designed after while shooting airsoft BBs as opposed to actual 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 gun pistols. Each of these kinds of handguns has benefits and differences connected with them. Finding out about the types of airsoft pistols lets you make a decision on which type is right for you and your airsoft gameplay style.

Details About CO2 Airsoft Sidearms

CO2 airsoft handguns are among the most popular and heavy-duty kinds of pistols. They are all-season, all-weather weapons and work well in many types of extreme temperatures, weather and environments. These sidearms use high pressure CO2 gas to force airsoft BBs out of the weapon barrel. The CO2 cartridge stores the gas within a cylinder and is generally located in the gun’s mag inside the handle.

These forms of airsoft handguns are very good for playing in colder weather conditions due to the fact that the compressed CO2 gas is less susceptible to variation by temperature levels. This fact offers excellent FPS and shot consistency while playing airsoft in the winter for example where other styles of sidearms like green gas stuffer from low performance or hardly shoot airsoft BBs.

Info About CO2 Gas and CO2 Cylinders

CO2 airsoft pistols are powered by basic 12 gram CO2 cylinders. These cartridges resemble a metallic cylinder and hold high pressure CO2 gas made up of a single carbon atom and a couple of oxygen atoms for this reason the molecular formula of “C + O2”.

They come sealed to keep the CO2 gas securely inside, however soon after they are opened (firing them inside of an airsoft pistol breaks the cartridge 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 opportunity to do some handgun target practice and use up the rest of the excess gas.

CO2 cartridges have a long storage life if they are stored sealed. They do have a manufacturer’s expiry date typically printed on the box or cartridge cylinder, but they will maintain pressure for a very long period past this date if the cartridge seals are not broken.

Green Gas and Propane Airsoft Handgun Facts

Green gas airsoft handguns function similarly to CO2 guns, but they do not use CO2 cartridges. Alternatively, they use green gas or propane for propellant to propel the airsoft BBs. The operational impact on the airsoft battlefield and green gas sidearm operation is essentially the same as CO2 pistols with the guns shooting up to about 300+ feet per second. Shots are rapidly fired in automatic or semi-automatic shooting modes and can accurately hit targets at shorter to mid-range proximities.

The green gas is stored in the handgun’s mag and can commonly hold between 15 to 20+ BBs depending on the pistol model. A series of valves, silicone gaskets, and o-rings keep the green gas pressurized in the pistol magazine up until the pistol’s trigger is pulled. It is a good choice to top off and refill the green gas reserves in the magazine each time you load it into the handgun. Pistol-wielding airsoft players can additionally bring additional bottles of green gas in the field for refilling in-between breaks in the battle or between missions.

When playing with a green gas pistol on the airsoft field or arena as a primary or backup gun, bringing extra pistol mags is recommended for quickly reloading and engaging the op force. Having additional magazines helps you reengage in the action in the middle of firefights or while clearing structures in CQB (close quarters combat) room-to-room combat.

Green gas handguns are excellent for CQB at airsoft fields since long guns and full-sized AEGs are generally not approved to be used for indoor gameplay. This is an essential safety standard because of the close range distance of gamers during shooting engagements. While green gas handguns still shoot airsoft BBs at about 300 FPS, the short pistol barrel assists to keep the joules and energy sending the BB lower compared to AEGs, sniper rifles, and long guns.

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

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

About GBB and Green Gas Issues

Since the green gas or propane gas is stored in the handgun mag by using rubber seals and silicone gaskets, cold temperatures can negatively affect these o-rings and allow the gas to escape before shooting the pistol. This can make the airsoft BBs to merely land a few feet (like 10 feet in cold temps ) when the green gas handgun would normally shoot 6mm BBs over 100+ foot distances in warmer temps).

One option to fix this challenge is to try to keep the GBB pistol magazines warmer by placing them near your body just before the game play. This can help to warm up the seals and valves and better seal in the green gas. If you honestly want to play airsoft with a reputable airsoft handgun in the cold, it may also be better to check out a CO2 version of your preferred pistol. The CO2 cartridges come sealed and these guns shoot much better in sub-freezing temperatures and while playing in the snow.

Facts About Spring Airsoft Handguns

Spring airsoft pistols are powered by strong coil springs that fire the BBs out of the handgun barrel. They are normally able to only shoot one BB. The manual actions of cocking, reloading, and firing spring guns makes the weapon’s fire rate much slower than CO2, green gas, and GBB handguns. This makes spring airsoft guns fun to use, however they are less practical when encountering opponents on the airsoft field with advanced weaponry, automatic airsoft AEG rifles, SMGs, sniper rifles, and CO2, green gas, or GBB airsoft handguns.

Spring pistols work most effectively in springer wars where airsoft players can solely use comparable, single shot spring guns or as a close quarters weapon for CQB buildings and MOUT sites when you can often surprise other airsoft game players to get an assured one-shot-one-kill. In the latter case, a fast 2nd followup shot isn’t required because the other person is now hit by the first BB and out of the gameplay or heading back to respawn. Be careful when engaging multiple adversaries since the springer just fires as quickly as you can re-chamber an airsoft BB manually.

About Spring Pistol Performance

Spring pistols are considerably efficient under the best conditions during airsoft games. Their FPS typically chronos at around 250 FPS to 300 FPS with 0.12 gram airsoft BBs. These weapons typically fire lighter weight airsoft BBs because the springs are less effective than other kinds of airsoft guns like SMGs. Spring pistols can normally be accurate at up to 120 feet or more with 0.12g BBs but the ability to engage targets accurately diminishes rapidly. Using conventional 0.20 gram weight airsoft BBs, you will most likely have a decreased range of around 60 to 80 feet or less with increased precision.

Info on AEG Automatic Electric Airsoft Sidearms

AEG airsoft sidearms or AEPs (automatic electric pistols) are also a good choice to use as a backup weapon on the airsoft field. These automatic electric pistols are often powered by mini stick batteries in the pistol’s butt. They work just like an AEG SMG and use pressured air with electrically cycled cylinders and gearboxes to propel airsoft BBs out of the barrel and rapidly.

AEG pistol mags generally hold about 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs as high as about 300 FPS using 0.12g airsoft BBs or 200 to 250 FPS when loaded with 0.20 gram airsoft BBs. The electrically powered gearbox system can shoot around 700+ 6mm BBs per minute which depends on if you have enough magazines to maintain the ammo supply and the battery maintains its charge that long. These pistols can efficiently shoot airsoft BBs at about 150 foot ranges.

AEG Pistol Quality and Efficiency

AEG pistol quality has actually grown significantly in recent years. The earliest generation guns were a little bit unreliable and sketchy, however the latest designs have the bugs worked out and make effective airsoft secondary guns. They can be modded with enhanced mag capacities and by accommodating larger batteries.

A huge advantage of carrying an AEG handgun is that you have the ability to rewire the connectors to use a larger capacity battery. Depending on the AEG handgun model, you can get a large output in functionality by employing a two cell Lipo battery (like an 2S Lipo) rather than the stock battery.

What Airsoft Pistol is Right for Me?

If you have over one-hundred dollars to spend on your airsoft handgun, evaluate a green gas blowback pistol or AEG pistol. If you have in-between fifty to one-hundred dollars to spend, look at a CO2 pistol or more affordable GBB handgun. You can still look for a long lasting airsoft pistol by checking out cheaper pistols and by shopping for used pistols if you are looking for a deal.
