Information About the Varieties of Airsoft Handguns

Learn about airsoft sidearms, pistols, and handguns and how you can use them as backup weapons or as core weapons on the airsoft playing field. A lot of airsoft pistols are fully manufactured and licensed variations of their real weapon counterparts and look and function in the exact same ways while shooting airsoft BBs instead of real bullets.

There are several kinds of airsoft sidearms including CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun pistols. Each of these forms of pistols has benefits and differences connected with them. Learning more about the styles of airsoft handguns helps you choose which type is right for you and your airsoft game play style.

CO2 Airsoft Sidearms

CO2 airsoft handguns are one of the most common and dependable kinds of pistols. They are all season, all weather guns working well in a lot of kinds of weather, extreme temperatures, and climates. These handguns use high pressure CO2 gas to launch airsoft BBs down the weapon barrel. The CO2 cartridge stores the gas within a cylinder and is typically located in the gun’s magazine.

These styles of airsoft guns are exceptional for playing airsoft in colder temperatures because the high pressure CO2 gas is stored in the sealed cylinders and less prone to variation with low temperature. This fact gives CO2 airsoft handguns great FPS and shot consistency while playing airsoft in the winter season for instance where other kinds of airsoft pistols like green gas stop functioning or hardly shoot airsoft BBs.

Information About CO2 Gas and CO2 Cartridges

CO2 airsoft sidearms are powered by regular 12 gram CO2 cartridges. These cartridges resemble a metal cylinder and hold high-pressure CO2 gas made up of just one carbon atom and 2 oxygen atoms, hence the molecular formula is “C + O2 “. These atoms are attached in the following alignment “O= C =O”. The gas is held in the 12 gram cartridges under very high pressure of roughly ~ 800psi that translates to 55bar.

They come sealed to keep the CO2 gas securely within, however soon after they are opened (shooting them in an airsoft handgun breaks the seal) they will start to lose pressure if they are left unused. If the airsoft matches end and you still have CO2 gas left, use the opportunity to do some pistol target practice and use up the rest of the extra gas.

If they are kept sealed, CO2 cartridges can be stored for a while. They have a manufacturer’s use by date normally noted on the box or cartridge, however, they will likely maintain pressure for a very long time past this date if the cartridge seal is not tampered with.

Green Gas and Propane Airsoft Handgun Info

Green gas airsoft handguns are similar to CO2 pistols, but they do not use CO2 cartridges. As an alternative, they use green gas or propane for propellant to shoot the airsoft pellets. The result on game play and green gas sidearm effectiveness is almost the same as CO2 pistols with the guns shooting up to 300+ FPS. Shots are rapidly fired in fully-automatic or semi-automatic firing modes and can hit targets at short to mid-range proximities.

The green gas is sealed in the handgun’s grip within the magazine which can typically hold around 15 to 20+ BBs based on the pistol design. A set of valves, silicone stoppers, and o-rings keep the propane gas pressurized in the magazine prior to when the pistol’s trigger is pulled. It is a good idea to top off and refill your propane supply in your pistol mag each time you load it into the pistol. Pistol-wielding gamers can additionally bring surplus bottles of green gas or propane in the field for reloading mags in-between lulls in the battle or between missions.

When running a green gas sidearm on the airsoft field as a backup or main gun, bringing additional mags is strongly recommended for quickly reloading and getting back into the game. Having additional mags on-hand allows you to join in the action throughout firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas pistols are optimal for CQB at airsoft fields since rifles, long guns, and full-sized AEGs are usually not allowed to be used during indoor engagements. This is a safety regulation due to the close quarters distance of players during shooting engagements and potential for players to get hurt. While green gas pistols can still fire airsoft BBs at about 300 FPS, the short handgun barrel assists to keep the joules and energy propelling the BB lower compared to AEGs, airsoft rifles, sniper rifles, and long guns.

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

There are 2 different types 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 fixed slide which does not move.

About GBB and Green Gas Limits

Since the green gas or propane is stored in the mag by rubber o-rings, seals, and silicone gaskets, cold temperatures can negatively impact these gaskets and cause the gas to escape prior to shooting the gun. This can make the airsoft BBs to just land a couple of feet away (like 10 feet in the cold ) when the gun would normally shoot 6mm BBs over 100+ feet in warmer temps).

One solution to this problem is to try to keep the GBB pistol mags warmer by putting them near your body before game play. This can help to warm up the rubber seals and better seal in the green gas. If you honestly prefer to play airsoft with a trustworthy airsoft handgun in the cold, it may also be worth buying a CO2 variation of your preferred pistol. The CO2 cylinders come sealed and these guns shoot far better in sub-freezing conditions and while playing in the snow.

Spring Airsoft Pistols

Spring airsoft handguns are powered by powerful springs with irregular pitches that launch the airsoft BBs down the handgun barrel. They are normally able to only shoot one BB. The manual actions of cocking, reloading, and firing spring guns makes the fire rate much slower than CO2, green gas, and GBB handguns. This makes spring guns interesting to use, yet they can be less practical when shooting at players on the airsoft field with advanced guns like automatic airsoft AEG rifles, SMGs, sniper rifles, and CO2 or GBB airsoft handguns.

Spring sidearms work most effectively in springer wars where participants can only use comparable, single shot spring weapons or as an alternative weapon for CQB environments when you can frequently sneak up to other airsoft game players to get a guaranteed one-shot-one-kill. In the latter circumstance, a fast second follow-up shot isn’t needed given that the other player is now hit by the airsoft BB and out of the game play or running back to respawn. Take care when fighting numerous foes considering that the spring gun just fires as quick as you can re-chamber an airsoft BB manually.

About Spring Pistol Efficiency

Spring guns are extremely effective under the proper game conditions. Spring handguns can commonly fire up to 120 feet or more with 0.12 gram BBs however the ability to engage targets reduces rapidly.

Facts About AEG Automatic Electric Airsoft Pistols

AEG airsoft handguns or AEPs (automatic electric pistols) are also a good choice to bring as a secondary gun on the airsoft field. These automatic electric handguns are often powered by mini stick batteries in the gun’s grip. They work just like an AEG gun and use pressurized air forced through electrically cycled cylinders and gearboxes to propel airsoft BBs out of the barrel and rapidly.

AEG handgun magazines generally can hold about 20 to 30 airsoft BBs. The handguns can launch 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 over the last few years. The early gen AEP guns were a little bit questionable and undependable, but the new models have most of the bugs resolved and make reliable airsoft backup guns. They can be further modded with increased magazine storage capacities together with accommodating bigger batteries.

A large advantage of carrying an AEG handgun is that you have the ability to rewire the adapters to use an enhanced capacity battery. Based on the AEG pistol design, you can get a sizable leap in functionality using a 2 cell Lipo battery (like an 2S Lipo) in place of the standard AEP battery. Take care of adjusting the parts and wires since you should take into account the voltages, mAh, and electrical loads of the batteries. Ask an expert gun technician at your local airsoft shop if you have modding questions.

Which Airsoft Sidearm is Right for Me to Buy?

Picking the best airsoft handgun for you depends upon how much you want to spend, how often you want to play airsoft using it, and where you decide to play. If you have over $100 to invest in your airsoft handgun, check out a green gas blowback or GBB handgun or AEG handgun. These guns are normally the best of the best, have great efficiency, and are usually a good airsoft gun to invest in. Consider a CO2 pistol or less expensive GBB handgun if you have between more than $50 but less than $100 to spend. These guns will still work well and will be pretty long lasting sidearms. If you have less than $50, search for a cheap CO2 or spring pistol. You can still buy a well-built airsoft pistol to use for the pistol games.
