How to Pick an Airsoft Handgun
Find information about airsoft pistols and sidearms and how you can use them as backup guns or as main weapons on the airsoft playing field. Numerous airsoft pistols are completely certified variations of their actual weapon counterparts and operate and look in the very same ways while shooting airsoft BBs rather than real bullets.
There are several types of airsoft handguns consisting of CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these styles of handguns has negatives and positives related to them. Learning more about the kinds of airsoft sidearms allows you to make a decision on which type is right for you and your airsoft game play style.
CO2 Airsoft Pistol Details
CO2 airsoft guns are one of the most long-lasting and standard types of sidearms. These handguns use sealed CO2 gas cylinders to push airsoft BBs out of the handgun barrel.
These types of airsoft pistols are exceptional for airsoft games in cold and snowy weather conditions given that the compressed CO2 gas is stored in the sealed cylinders and less sensitive to variation caused by temperature. This fact provides excellent FPS and shot consistency while playing airsoft in the cold weather for example where other styles of pistols like green gas cease to operate or barely shoot pellets.
Info About CO2 Gas and CO2 Cylinders
CO2 airsoft guns are powered by basic 12 gram CO2 cartridge cylinders. These cartridges look like a shiny steel cylinder and store high pressured CO2 gas consisting of a single carbon atom and two oxygen atoms, thus the molecular formula is “C + O2 “. These atoms are bound in the following sequence “O= C =O”. The gas is held in the 12 gram cylinders under extremely high pressure of approximately ~ 800psi which correlates to 55bar.
The CO2 cartridge cylinders are not multiple-use and you can commonly order them in packs of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to retain the CO2 gas safely inside, once they are opened (shooting them inside of an airsoft pistol breaks the seal) cartridges will begin to lose pressure if they are not used up. You need to try to dissipate the whole CO2 cartridge the same day you open the seal. Use the opportunity to do some pistol target practice and use up the rest of the excess gas if the airsoft games 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 pistol stops shooting.
If they are kept sealed, CO2 cartridges have a long storage life. They have a manufacturer’s best used by date typically noted on the package or cylinder, but they may last for a long period past this date if the cartridge seals are not punctured.
Green Gas and Propane Airsoft Handgun Facts
Green gas airsoft handguns function similarly to CO2 guns, but they do not use CO2 cartridges. Rather, they use green gas or propane gas for propellant to shoot the airsoft pellets. The operational impact on airsoft games and green gas pistol operation is essentially the same as CO2 handguns with the weapons shooting up to about 300+ feet per second (FPS). Shots are quickly fired in automatic or semi-automatic firing modes and can hit targets at short to mid-range distances.
The green gas is held in the handgun’s airsoft mag which can usually hold in-between 15 to 20+ airsoft BBs depending on the handgun design. A series of valves, rubberized gaskets, and silicone seals keep the gas stored in the mag until the pistol’s trigger is pulled.
When carrying a green gas pistol on the airsoft field or arena as a backup or main gun, additional magazines are encouraged for quickly reloading and getting back into the game. Having additional mags allows you to reengage in the action during firefights or while sweeping structures in CQB (close quarters combat) room-to-room fights.
Green gas pistols are ideal for CQB at airsoft fields since rifles, long guns, and full-sized AEGs are normally not approved to be used during indoor shooting. This is an essential safety standard because of the close quarters proximity of gamers during shooting engagements. While green gas handguns still fire airsoft BBs at around 300 FPS, the short handgun barrel helps to keep the joules and energy propelling the BB at a lower level compared to AEG airsoft rifles, sniper rifles, and long guns.
About Green Gas Blowback (GBB) VS Green Gas Non-blowback
There are two various varieties of green gas airsoft handguns. There are green gas blowback handguns or GBBs and non-blowback handguns. 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 kept in the mag using rubber o-rings, seals, and silicone gaskets, the cold can influence these seals and allow the gas to escape prior to shooting the pistol. The lack of pressure can make the airsoft BBs to just land a number of feet away (like 10 feet in cold weather ) when the pistol would usually shoot airsoft BBs over 100+ feet in warmer weather conditions).
One solution to this problem is to make the GBB handgun magazines warmer by holding them next to your body or near a heat source before game play. If you truly need to play with a reliable airsoft handgun in the cold weather, it might additionally be worth getting a CO2 style of your preferred handgun.
Spring Airsoft Sidearm Info
Spring airsoft handguns are powered by powerful springs that fire the BBs out of the pistol barrel. The manual functions of reloading, firing, and cocking spring handguns makes the fire rate much slower than CO2, green gas, and GBB airsoft guns.
Spring guns work best in springer wars where airsoft players can just use related, single shot spring weapons or as a transition backup weapon for CQB buildings and MOUT sites when you can often sneak up to other airsoft game players to get an assured one-shot-one-kill. In the latter scenario, a rapid second followup shot will not be really needed considering that the other opponent is already hit by the first shot and out of the game or going back to respawn. When engaging a number of airsoft players since the spring airsoft gun just fires as quickly as you can re-chamber an airsoft BB by hand, be careful.
About Spring Handgun Efficiency
Spring handguns are extremely effective under the most ideal conditions during games. Their FPS often chronos at about 250 FPS to 300 FPS with lighter 0.12g airsoft BBs. These pistols typically fire lighter weight airsoft BBs since the springs are less powerful than other styles of airsoft weapons. Spring handguns can normally shoot up to 120 feet or more with 0.12g BBs however the ability to engage targets accurately decreases quickly. Using conventional 0.20g weight airsoft BBs, you will most likely have a decreased shooting distance of around 60 to 80 feet with heightened precision.
AEG Automatic Electric Airsoft Handguns
AEG airsoft pistols or AEPs (automatic electric pistols) are also a viable option to use as a backup weapon on the airsoft field. These automatic electric handguns are commonly powered by mini stick batteries in the weapon’s butt. They operate similar to an AEG SMG and use forced air with electrically cycled gearboxes and cylinders to propel airsoft BBs out of the barrel and very rapidly at that.
AEG handgun magazines usually carry about 20 to 30 airsoft BBs. The handguns can fire airsoft BBs up to about 300 FPS using 0.12g airsoft BBs or 200 to 250 FPS with 0.20 gram airsoft BBs.
AEG Handgun Quality and Performance
AEG pistol quality has risen considerably in the last few years. The early gen AEP guns were a little bit sketchy and undependable, but the latest designs have the problems resolved and make effective airsoft secondary guns. They can be further modded with maximized magazine storage capacities as well as accommodating bigger batteries.
A significant benefit of using an AEG handgun is that you have the power to rewire the adapters to use a larger battery. Depending on the AEG handgun design, you can get a sizable increase in efficiency by adopting a 2 cell Lipo battery (like an 2S Lipo) instead of the stock battery.
Which Airsoft Pistol is Best for Me to Play with?
If you have $100 or more to use to buy your airsoft pistol, evaluate a green gas blowback handgun or automatic electric pistol. If you have between $50 to $100 to upgrade your gun, look at a CO2 pistol or more affordable GBB handgun. If you have $50 or less, you can still choose a resilient airsoft handgun to use for the handgun games by checking out lower end pistols and by trading with other players on the used gun market.
