How to Choose an Airsoft Pistol

Find info about airsoft pistols and handguns and how you can use them as backup guns or as main weapons on the airsoft playing field. Practicing your accuracy and getting the best handgun can be a game changer in aiming your shots. Sidearms, naturally, are much shorter range airsoft guns. They are frequently designed after real world handguns or look-alikes of legitimate pistols. A large number of airsoft handguns are fully certified reproductions of their genuine firearm equivalents. These airsoft guns can visually look and run in the same ways almost identically to the real guns they are modeled around while shooting airsoft BBs in place of genuine bullets.

There are a variety of airsoft handguns such as CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric pistols. Each of these varieties of sidearms come with benefits and differences associated with them. Learning about the varieties of airsoft handguns allows you to choose which type is right for you and your airsoft game play style.

CO2 Airsoft Sidearm Details

CO2 airsoft handguns are among the most long lasting and typical kinds of pistols. They are all weather pistols and work well in a lot of kinds of extreme temperatures, weather and environments. These handguns use high pressure CO2 gas to launch airsoft BBs down the pistol barrel. The CO2 cartridge stores the gas and is typically housed in the handgun’s magazine.

These forms of airsoft guns are good for playing in cooler weather since the pressurized CO2 gas is less vulnerable to performance variations with temperature. This provides good FPS and shot consistency while playing airsoft in the winter season for example where other varieties of guns like green gas stuffer from low performance or barely shoot BBs.

Information About CO2 Gas and CO2 Cylinders

CO2 airsoft sidearms are powered by basic 12 gram CO2 cylinders. These cartridges look like a shiny metallic cylinder and store high pressured CO2 gas composed of a single carbon atom and two oxygen atoms hence the molecular formula is “C + O2”.

The CO2 cartridges are not refillable and you can usually buy them in packs of 12, 20, 50, or 100 12 gram CO2 cartridge sets. They come sealed to retain the CO2 gas safely within, once they are opened (firing them inside of an airsoft pistol breaks the cartridge seal) they will begin to lose pressure if they are not used up. You must attempt to consume the whole CO2 cartridge the same day you open the seal. Use the chance to do some pistol target practice and use up the rest of the additional gas if the airsoft matches end and you still have CO2 gas left. There is no gas level sign on the cartridge so you need to shoot up until the handgun stops shooting BBs.

CO2 cartridges can be stored for a while if the cylinders are stored sealed. They have the manufacturer’s expiry date usually marked on the box or cartridge cylinder, however, they may last for a very long time past this date if the cartridge seal is not damaged.

Green Gas and Propane Airsoft Sidearms

Green gas airsoft sidearms are similar to CO2 handguns, however they do not use CO2 cartridges. Alternatively, they use green gas or propane for propellant to propel the airsoft BBs. The result on the airsoft battlefield and green gas pistol functionality is just about the same as CO2 pistols with the guns shooting up to 300+ feet per second. Shots are efficiently fired in semi-automatic or fully-automatic firing modes and precisely hit targets at short to mid-range proximities.

The green gas is kept in the pistol’s mag which can often hold around 15 to 20+ airsoft BBs depending upon the handgun style. A series of valves, silicone gaskets, and seals keep the green gas stored in the pistol mag up to when the handgun’s trigger is squeezed. It is a great idea to fill up and top off your green gas reserves in the pistol mag each time you load it into the pistol. Pistol-wielding airsoft players can even take additional bottles of propane in the field for refilling magazines between breaks in the battle or in-between activities.

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

Green gas pistols are optimal for CQB at airsoft fields considering that rifles, long guns, and full-sized AEGs are usually not authorized to be used during indoor engagements. This is a safety regulation because of the close quarters proximity of players during shooting engagements. While green gas handguns can still shoot airsoft BBs at about 300 FPS, the shorter pistol barrel assists to keep the joules and energy forcing the BB at a lower level compared to AEGs, sniper rifles, and other long guns.

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

There are two different forms of green gas airsoft handguns. To start with there are green gas blowback handguns or GBBs. These handguns work like a legitimate pistol with the gun’s slide “blowing back” and moving with every shot. The propane gas induces the slide to cycle each time when a brand-new airsoft BB is chambered. This effect is extremely cool, however the weapons often cost more and likely have more parts to break. The green gas non-blowback airsoft handguns use a stationary slide which does not move. The non-blowback handguns generally cost less than GBBs. Efficiency is around the same between the two kinds of green gas pistols.

About GBB and Green Gas Limitations

While green gas generally functions extremely well on the airsoft field, it does have drawbacks. When green gas and GBB guns are used over the winter in the snow or in colder temperatures (such as below 32 deg F). Since the green gas or propane gas is held in the pistol mag using rubber seals, o-rings, and gaskets, the cold can impair these seals and allow the stored gas to escape before shooting airsoft BBs. This can make the airsoft BBs to just shoot a couple of feet (like 10 feet in cold temps ) when the gun would typically shoot airsoft BBs over 100+ foot ranges in warmer temperatures).

One option to this problem is to make the GBB pistol magazines warmer by putting them next to your body just before game play. If you truly need to play with a reliable airsoft handgun in the cold, it may also be worth getting a CO2 style of your preferred handgun.

Spring Airsoft Handgun Information

Spring airsoft sidearms are powered by powerful springs with irregular pitches that launch the airsoft BBs down the gun barrel. They are typically able to only shoot one BB. The manual functions of cocking, reloading, and firing spring guns makes the weapon’s fire rate much slower than CO2 and GBB pistols. This makes spring airsoft guns fun to use, however they are less effective when dueling competitors on the airsoft field with upgraded weapons, fully automatic airsoft AEG SMGs and CO2, green gas, or GBB airsoft pistols.

Spring guns work the best in springer wars where participants can only use comparable, single shot spring handguns or as a transition weapon for CQB buildings and MOUT sites when you can often surprise other airsoft participants to get an assured one-shot-one-kill. In the latter case, a rapid second followup shot will not be required considering that the other person is now hit by the first shot and out of the game play or moving back to respawn. When engaging several players since the springer simply shoots as quickly as you can re-chamber an airsoft BB manually, be careful.

About Spring Pistol Efficiency

Spring guns are very efficient under the correct conditions during airsoft games. Spring guns can usually shoot up to 120 feet or farther with 0.12g BBs but accuracy decreases rapidly.

Facts About AEG Automatic Electric Airsoft Pistols

AEG airsoft handguns or AEPs (automatic electric pistols) are definitely an option to bring into the field as a backup gun on the airsoft field. These automatic electric handguns are normally powered by mini stick batteries in the gun’s grip. They work similar to an AEG gun and use forced air with electrically cycled gearboxes, pistons, and cylinders to propel airsoft BBs quickly and very rapidly at that.

AEG handgun mags generally can carry around 20 to 30 airsoft BBs. The pistols can fire airsoft BBs up to around 300 FPS with 0.12 gram airsoft BBs or 200 to 250 FPS with 0.20g airsoft BBs.

AEG Pistol Quality and Efficiency

AEG handgun quality has actually grown considerably recently. The first generation guns were a bit unreliable and sketchy, but the new versions have most of the bugs resolved and make effective airsoft secondary weapons. They can be further modified with enhanced magazine capacities and also accommodating more powerful batteries.

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

What Airsoft Pistol is Best for Me?

If you have $100 or more to use to buy your airsoft handgun, check out a green gas blowback pistol or automatic electric pistol. If you have between $50 to $100 to invest, evaluate a good quality CO2 handgun or more affordable GBB handgun. If you have less than $50, you can still look for a resilient airsoft handgun to use for the pistol games by checking out lower end pistols and by shopping the used airsoft gun market.
