About the Types of Airsoft Handguns

Learn more about airsoft pistols and sidearms and how you can use them as backup guns or as main weapons on the airsoft playing field. Practicing your shot accuracy and getting the right handgun can be a game changer in hitting your shots. Pistols, naturally, are lower range airsoft weapons. They are commonly produced after actual guns or miniatures of actual pistols. A large number of airsoft pistols are completely certified variations of their real world weapon equivalents. These airsoft guns can visually appear and function (except for shooting bullets) in the same ways identically to the real guns they are designed around while blasting airsoft BBs instead of authentic bullets.

There are several types of airsoft sidearms consisting of CO2, green gas or propane (blowback and non-blowback), spring powered, and AEG automatic electric pistols. Each of these types of sidearms has negatives and positives related to them. Finding out about the types of airsoft pistols helps you decide which type is right for you and your airsoft play style.

Details About CO2 Airsoft Sidearms

CO2 airsoft pistols are among the most heavy duty and popular types of pistols. They are all-season guns working well in a lot of types of weather, temperatures, and climates. These handguns use high pressure CO2 gas to force airsoft BBs out of the handgun barrel. The CO2 cartridge is generally housed in the gun’s magazine inside the handle.

These kinds of airsoft pistols are exceptional for airsoft games in cold temperatures due to the fact that the pressurized CO2 gas is stored in the sealed cylinders and less susceptible to performance decreases with low temperatures. This offers great FPS and shot consistency while playing airsoft in the winter months for instance where other kinds of airsoft pistols like green gas stop performing or barely shoot BBs.

About CO2 Gas and CO2 Cartridges

CO2 airsoft pistols are powered by standard 12 gram CO2 cartridge cylinders. These cartridges resemble a metal cylinder and hold high-pressure CO2 gas composed of one carbon atom and two 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 held in the 12 gram cylinders under very high pressure of near ~ 800psi which correlates to 55bar.

The CO2 gas cartridges are not refillable and you can normally order them in packs of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to preserve the CO2 gas securely inside, but once they are opened (shooting them inside of an airsoft handgun breaks the seal) they will begin to lose pressure if they are not used up. You need to attempt to deplete the entire CO2 cartridge the same day you open the seal. If the airsoft matches end and you still have CO2 gas leftover, use the chance to do some pistol target practice and consume the remainder of the surplus gas. There is no gas level sign on the cartridge so you need to shoot until the handgun stops firing BBs.

CO2 cartridges have a long storage life if the cylinders are stored sealed. They do have the maker’s expiration date typically listed on the box or cylinder, however they will maintain pressure for a prolonged time past this date if the cartridge seal is not broken.

Green Gas and Propane Airsoft Handguns

Green gas airsoft handguns are comparable to CO2 pistols, however they do not use CO2 cartridges. The impact on the airsoft battlefield and green gas weapon performance is virtually the exact same as CO2 pistols with the weapons shooting up to 300+ FPS.

The green gas is kept in the handgun’s magazine which can typically hold around 15 to 20+ airsoft BBs depending upon the handgun style. A series of valves, rubber stoppers, and o-rings keep the propane gas sealed in the pistol magazine until the handgun’s trigger is pulled. It is a great idea to fill up and top off your propane supply in the mag each time you reload it. Pistol-wielding gamers can even bring extra bottles of propane gas in the field for refilling magazines between lulls in the war or in-between games.

When playing with a green gas pistol on the airsoft field or arena as a backup or main weapon, additional pistol mags are highly recommended for quickly reloading. Having extra magazines allows you to join in the action throughout firefights or while sweeping structures in CQB (close quarters combat) room-to-room fighting.

Green gas handguns are optimal for CQB at airsoft fields because rifles, long guns, and full-sized AEGs are usually not allowed to be used for indoor engagements. This is a safety guideline because of the close range distance of gamers during the shooting engagements and the potential for players to be injured. While green gas handguns can still shoot airsoft BBs at around 300 FPS, the shorter pistol barrel aids to keep the joules and energy pushing the BB lower compared to AEGs, sniper rifles, and long guns.

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

There are two different varieties 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 Limitations

Since the green gas or propane is stored in the magazine using rubber seals and silicone gaskets, cold temps can negatively influence these seals and cause the stored gas to escape prior to shooting the gun. This lack of pressure can cause the airsoft BBs to only shoot a number of feet away (like 10 feet in the cold ) when the green gas pistol would normally shoot airsoft BBs over 100+ feet in warmer temperatures).

One fix to this issue is to keep the GBB pistol mags warmer by placing them next to your body prior to game play starts. If you truly desire to play with a reputable airsoft handgun in the cold, it may additionally be worth getting a CO2 version of your preferred handgun.

Facts About Spring Airsoft Pistols

Spring airsoft handguns are powered by powerful coil springs that propel the airsoft BBs out of the handgun barrel. They are generally only able to shoot one BB. The manual actions of shooting, cocking, and reloading spring pistols makes the weapon’s fire rate much slower than CO2 and GBB handguns. When dueling airsoft players on the airsoft field with upgraded weapons, auto airsoft AEG assault rifles, SMGs, sniper rifles, and CO2 or GBB airsoft pistols, this can make spring airsoft guns enjoyable to use, but less effective.

Spring airsoft guns work most effectively in springer wars where participants can exclusively use similar, single shot spring handguns or as a transition backup gun for CQB environments when you can often sneak up to other airsoft game players to get an assured one-shot-one-kill. In the latter situation, a quick 2nd followup shot isn’t required since the other player is now hit and out of the game or moving back to respawn. When engaging many different adversaries given that the weapon simply shoots as quickly as you can re-chamber an airsoft BB manually, be careful.

About Spring Pistol Effectiveness

Spring guns are quite reliable under the most ideal game circumstances. Spring pistols can generally fire up to 120 feet or more with 0.12g BBs but the ability to engage targets reduces quickly.

AEG Automatic Electric Airsoft Pistols

AEG airsoft handguns or AEPs (automatic electric pistols) are also a viable option to use as a backup gun on the airsoft field. These automatic electric handguns are commonly powered by mini stick batteries in the gun’s butt. They operate just like an AEG gun and use compressed air with electrically cycled cylinders, pistons, and gearboxes to fire airsoft BBs out of the barrel and very rapidly at that.

AEG pistol magazines normally hold around 20 to 30 airsoft BBs. The pistols can launch airsoft BBs up to around 300 FPS using 0.12g airsoft BBs or 200 to 250 FPS using 0.20g airsoft BBs.

AEG Handgun Quality and Efficiency

AEG handgun quality has increased substantially recently. The first generations were a bit undependable and sketchy, but the latest designs have the bugs resolved and make efficient airsoft secondary guns. They can be further upgraded with enhanced magazine capacities along with accommodating more powerful batteries.

A large benefit of carrying an AEG pistol is that you have the ability to rewire the battery connectors to use a more substantial battery. Depending on the AEG handgun model, you can gain a big output in performance by using a 2 cell Lipo battery (like an 2S Lipo) as a replacement for the stock mini battery.

Which Airsoft Pistol is Right for Me to Play with?

If you have over $100 to spend on your airsoft handgun, check out a GBB handgun or AEG pistol. If you have in-between fifty to one-hundred dollars to shell out, check out a CO2 pistol or less expensive GBB pistol. You can still find a resilient airsoft pistol by checking out lower end pistols and by trading with players selling used airsoft pistols if you are trying to save money.
