How to Choose an Airsoft Handgun

Learn about airsoft sidearms and handguns and how you can use them as backup guns or as main weapons on the airsoft playing field. Getting the best pistol and practicing with it can make all the difference in hitting your shots. Sidearms, by nature, are lower range airsoft weapons. They are generally created after genuine handguns or look-alikes of real handguns. A lot of airsoft handguns are fully licensed variations of their real-world pistol counterparts. These airsoft guns can function (without shooting bullets) in the same ways and look identical to the real guns they are modeled around while firing airsoft BBs rather than real-world bullets.

There are a number of types of airsoft handguns such as CO2, green gas or propane (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these kinds of handguns has negatives and positives related to them. Learning about the types of airsoft sidearms allows you to decide which type is right for you and your airsoft gameplay style.

CO2 Airsoft Sidearms

CO2 airsoft sidearms are one of the most typical and heavy-duty types of handguns. They are all-season, all-weather pistols and function well in lots of types of weather conditions and environments. These handguns use high pressure CO2 gas to propel airsoft BBs down the handgun barrel. The CO2 cartridge stores the gas within a cylinder and is normally kept in the handgun’s magazine inside the handle.

These kinds of airsoft weapons are good choices for airsoft games in colder weather given that the high pressure CO2 gas is less prone to performance variations caused by low temperatures. This fact provides good FPS and shot consistency while playing airsoft in the winter months for instance where other styles of airsoft sidearms like green gas stuffer from low performance or hardly fire BBs.

Info About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft guns are powered by common 12 gram CO2 cartridge cylinders. These cartridges look like a metallic cylinder and contain high pressured CO2 gas composed of a single carbon atom and a pair of oxygen atoms, as a result of the molecular formula of “C + O2 “. These atoms are bonded in the following alignment “O= C =O”. The gas is stored in the 12 gram cylinders under really high pressure of near ~ 800psi that converts to 55bar.

The CO2 cartridge cylinders cannot be used multiple times and you can commonly buy them in packs of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to keep the CO2 gas safely and securely within, once they are punctured (firing them inside of an airsoft handgun breaks the seal) they will begin to lose pressure if they are not expended. You must try to dissipate the entire CO2 cartridge the very same day you open the seal. Use the chance to do some handgun target practice and use up the rest of the extra gas if the airsoft matches end and you still have CO2 gas left. There is no gas level gauge on the cartridge so you need to shoot up until the pistol stops firing BBs.

CO2 cartridges have a long storage life if they are stored sealed. They are made with the manufacturer’s use by date normally listed on the package or cartridge cylinder, however, they may last for a long time past this date if the cartridge seals are not tampered with.

Green Gas and Propane Airsoft Sidearms

Green gas airsoft pistols are similar to CO2 pistols, but they use green gas instead of CO2 cartridges. The result on the airsoft battlefield and green gas weapon efficiency is virtually the very same as CO2 pistols with the weapons shooting up to 300+ FPS.

The propane is stashed in the handgun’s airsoft magazine which can commonly hold between 15 to 20+ airsoft BBs based on the handgun type. A series of valves, rubberized gaskets, and silicone o-rings keep the gas stored in the magazine till the pistol’s trigger is pulled.

When playing with a green gas sidearm on the airsoft field as a main or backup weapon, additional handgun mags are suggested for rapidly reloading and engaging the op force. Having extra mags on-hand helps you re engage in the action in the middle of firefights or while clearing structures in CQB (close quarters combat) room-to-room fights.

Green gas pistols are optimal for CQB at airsoft fields since rifles and full-sized AEGs are normally not permitted to be used for indoor gameplay. This is a safety standard due to the close range proximity of players during the shooting engagements and the potential for players to be hurt. While green gas pistols still fire airsoft BBs at around 300 FPS, the short handgun barrel aids to keep the joules and energy pushing the BB at a lower level compared to AEG airsoft rifles, sniper rifles, and other long guns.

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

There are 2 various types of green gas airsoft pistols. There are green gas blowback pistols or GBBs. These handguns function like a genuine pistol with the pistol slide “blowing back” with every shot. Each time a fresh airsoft BB is chambered, the gas triggers the slide to cycle. The result is very cool, but the handguns typically cost more and likely have more parts which can break. The green gas non-blowback airsoft handguns use a fixed slide which does not move. The non-blowback pistols commonly cost less than GBBs. Performance is about the same when comparing the two types of green gas handguns.

About GBB and Green Gas Limitations

Because the green gas or propane is held in the pistol magazine by rubber seals, o-rings, and silicone gaskets, cold temperatures can impact these o-rings and allow the gas to leak out prior to shooting. This lack of pressure can make the airsoft BBs to only shoot a few feet away (like 10 feet in cold weather ) when the GBB handgun would typically shoot 6mm BBs over 100+ feet in warmer temperatures).

One fix for this challenge is to try to keep the GBB pistol mags warmer by putting them next to your body before game play. This can help to warm up the rubber gaskets and help to seal in the green gas. It may also be worth checking out a CO2 version of your preferred pistol if you truly prefer to play airsoft with a reputable airsoft pistol in the cold. The CO2 cylinders come sealed and the gun will shoot better in sub-freezing conditions and while playing in the snow.

Spring Airsoft Sidearms

Spring airsoft handguns are powered by strong springs that launch the BBs out of the gun barrel. They are generally able to only shoot one BB at a time. The manual functions of reloading, firing, and cocking spring airsoft guns makes the fire rate much slower than CO2, green gas, and GBB handguns. When fighting against adversaries on the airsoft field with upgraded rifles like auto airsoft AEG SMGs, assault rifles, sniper rifles, and CO2 or GBB airsoft handguns, this can make spring airsoft pistols entertaining to use, but less efficient.

Spring guns work most effectively in springer wars where players can exclusively use related, single shot spring pistols or as a transition backup weapon for CQB settings when you can often sneak up to other airsoft participants to get an assured one-shot-one-kill. In the latter circumstance, a fast second follow-up shot will not be required because the other opponent is already hit by the airsoft BB and out of the game play or running back to respawn. Beware when fighting several adversaries due to the fact that the weapon only shoots as quick as you can re-chamber an airsoft BB manually.

About Spring Handgun Performance

Spring guns are very reliable under the right circumstances and airsoft games. Their FPS usually chronos at about 250 FPS to 300 FPS with 0.12 gram airsoft BBs. These weapons usually fire lighter weight airsoft BBs due to the fact that the coiled springs are less effective than other kinds of airsoft guns like rifles. Spring guns can typically be accurate at up to 120 feet or more with 0.12 gram BBs however the ability to engage targets decreases quickly. Using conventional 0.20 gram weight airsoft BBs, you will very likely have a decreased shooting distance of about 60 to 80 feet or less with improved accuracy.

Info on AEG Automatic Electric Airsoft Sidearms

AEG airsoft sidearms or AEPs (automatic electric pistols) are also a good choice to use as a sidearm on the airsoft field. These automatic electric handguns are often powered by mini stick batteries in the weapon’s butt. They function similar to an AEG rifle and use compressed air pumped through electrically cycled gearboxes and cylinders to propel airsoft BBs quickly and rapidly.

AEG pistol magazines typically can hold about 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs approximately about 300 FPS when loaded with 0.12g airsoft BBs or 200 to 250 FPS using 0.20 gram airsoft BBs. The electric gearbox system can shoot around 700+ BBs per minute which depends if you have enough spare magazines to maintain the ammo supply and the battery holds out that long. These AEP pistols can accurately fire airsoft BBs at around 150 foot distances.

AEG Handgun Quality and Performance

AEG pistol quality has actually increased significantly over the last few years. The initial gens were a little bit unreliable and sketchy, but the new versions have the problems resolved and make efficient airsoft backup weapons. They can be improved with maximized magazine capacities in addition to accommodating bigger batteries.

A large perk of carrying an AEG handgun is that you have the capability to rewire the battery wires to use an enhanced capacity battery with higher mAh. Depending on the AEG handgun design, you are able to gain a big jump in efficiency by using a 2 cell Lipo battery (like an 2S Lipo) instead of the stock battery. Be careful with tweaking the components and wires because you have to think about the volts, mAh, and loads of the battery. Ask a qualified weapon tech at your closest airsoft shop if you have customization problems.

Which Airsoft Pistol is Best for Me to Play with?

If you have $100 or more to use to buy your airsoft pistol, check out a green gas blowback handgun or AEG pistol. If you have in-between fifty to one-hundred dollars to invest, review a CO2 handgun or more affordable GBB pistol. You can still play with a resilient airsoft pistol by checking out lower end pistols and by trading with other players in the used gun market if you are on a budget.
