How to Choose an Airsoft Pistol
Find information about airsoft handguns and pistols and how you can use them as backup weapons or as main weapons on the airsoft playing field. Practicing your accuracy and getting the ideal pistol can make an impact in the accuracy of your shots. Pistols, by nature, are lower range airsoft guns. They are quite often constructed after real world guns or replications of real pistols. Many airsoft pistols are fully licensed variations of their real handgun counterparts. These airsoft guns can appear and function (sans shooting bullets) in the same ways similarly to the real guns they are modeled around while firing airsoft BBs in place of real-world bullets.
There are a variety of airsoft sidearms consisting of CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun sidearms. Each of these forms of pistols have positives and negatives connected with them. Learning more about the varieties of airsoft pistols allows you to decide which type is right for you and your airsoft gameplay style.
Details About CO2 Airsoft Handguns
CO2 airsoft guns are one of the most popular and tough types of sidearms. These pistols use pressurized CO2 gas to shoot airsoft BBs out of the gun barrel.
These styles of airsoft pistols are good for playing in colder temperatures given that the high pressure CO2 gas is stored in the sealed cylinders and less susceptible to FPS decreases with low temperatures. This gives CO2 airsoft pistols great FPS and shot consistency while playing airsoft in the wintertime for instance where other kinds of airsoft pistols like green gas stop functioning or hardly shoot airsoft BBs.
About CO2 Gas and CO2 Cartridge Cylinders
CO2 airsoft sidearms are powered by regular 12 gram CO2 cartridge cylinders. These cartridges look like a metal cylinder and store high pressured CO2 gas comprised of 1 carbon atom and a couple of oxygen atoms, consequently the molecular formula is “C + O2 “. These atoms are connected in the following order “O= C =O”. The gas is held in the 12 gram cartridges under extremely high pressure of approximately ~ 800psi that translates to 55bar.
The CO2 cylinders cannot be refilled and you can usually buy them in packs of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to keep the CO2 gas securely within, once they are opened (shooting them in an airsoft pistol breaks the seal) they will start to lose pressure if they are not expended. You must try to expend the entire CO2 cartridge the same day you open the seal. If the airsoft matches end and you still have CO2 gas left, use the chance to do some pistol accuracy and target practice and consume the remaining excess gas. There is no gas level guide on the cartridge so you need to shoot until the handgun stops cycling.
CO2 cartridges can be stored for a while if they are stored sealed. They are made with a manufacturer’s use by date normally printed on the box or cartridge, but they may stay pressurized for a prolonged period past this date if the cartridge seal is not broken.
Information About Green Gas Airsoft Sidearms
Green gas airsoft handguns are similar to CO2 handguns, but they do not use CO2 cartridges. Rather, they use green gas or propane for propellant to fire 6mm airsoft pellets. The result on airsoft games and green gas sidearm effectiveness is just about the same as CO2 pistols with the weapons shooting up to about 300+ FPS. Shots are efficiently fired in automatic or semi-automatic shooting modes and accurate at very short to mid-range ranges.
The propane is held in the pistol’s airsoft mag that can usually hold in-between 15 to 20+ BBs depending on the pistol design. A series of valves, rubber gaskets, and silicone o-rings keep the gas pressurized in the mag till the handgun’s trigger is pulled.
When running a green gas sidearm on the airsoft field as a backup or primary gun, bringing additional handgun mags is highly recommended for quickly reloading. Having extra mags on-hand allows you to join in the action throughout firefights or while clearing buildings in CQB (close quarters combat) room-to-room battles.
Green gas pistols are excellent for CQB at airsoft fields considering long guns and full-sized AEGs are normally not authorized to be used for indoor shooting. This is a safety guideline because of the close range distance of gamers during the shooting engagements and potential for players to get hurt. While green gas handguns still shoot airsoft BBs at around 300 FPS, the short pistol barrel helps to keep the joules and energy forcing the BB at a decreased level compared to AEGs, airsoft rifles, sniper rifles, and long guns.
About Green Gas Blowback (GBB) VS Green Gas Non-blowback
There are 2 different varieties of green gas airsoft handguns. To start with there are green gas blowback handguns or GBBs. These guns operate like a realistic handgun with the pistol slide “blowing back” and cycling with every shot. The gas triggers the slide to cycle every time when a new airsoft BB is loaded into the chamber. The result is extremely cool, but the GBB weapons frequently cost more and possibly have more to break. The green gas non-blowback airsoft handguns have a stationary slide which does not move. The non-blowback weapons typically cost less than GBBs. Performance is about the same between the two varieties of green gas pistols.
About GBB and Green Gas Limits
While green gas normally can be used effectively on the airsoft field, it does have limits. When green gas and GBB guns are used over the winter playing in the snow or in cold weather (such as under 32 degrees F). Given that the green gas or propane gas is stored in the mag using silicone seals, o-rings, and gaskets, cold temperatures can impact the seals and trigger the gas to escape prior to shooting airsoft BBs. This can make the airsoft BBs to merely shoot a few feet (like 10 feet in cold temps ) when the pistol would usually shoot airsoft BBs over 100+ foot distances in warmer temps).
One option to this issue is to keep the GBB pistol mags warmer by putting them next to your body or by a heater just before game play starts. If you truly want to play with a reliable airsoft pistol in the cold, it might additionally be worth getting a CO2 variation of your preferred handgun.
Spring Airsoft Pistol Info
Spring airsoft sidearms 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 at a time. The manual functioning of cocking, reloading, and firing spring guns makes the fire rate much slower than CO2, green gas, and GBB handguns. This makes spring guns enjoyable to use, but they are usually less effective when facing attackers on the airsoft field with upgraded weapons and fully auto airsoft AEG rifles and CO2 or GBB airsoft pistols.
Spring pistols work the best in springer battles where players can exclusively use comparable, single shot spring weapons or as a transition backup gun for CQB buildings when you can often sneak up to other airsoft opponents to get an assured one-shot-one-kill. In the latter case, a fast 2nd follow-up shot isn’t required since the other person is already hit by the first BB and out of the game play or running back to respawn. Take care when fighting a number of players considering that the gun only fires as fast as you can re-chamber an airsoft BB manually.
About Spring Handgun Efficiency
Spring guns are remarkably efficient under the most ideal game conditions. Their FPS normally chronos at around 250 FPS to 300 FPS with 0.12g airsoft BBs. These pistols usually fire the lighter weight airsoft BBs because the coiled springs are less powerful than other styles of airsoft guns like rifles. Spring pistols can generally engage targets at ranges of up to 120 feet or more with 0.12g BBs but the ability to engage targets accurately decreases quickly. Shooting normal 0.20 gram weight airsoft BBs, you will very likely have a decreased range of around 60 to 80 feet or less with enhanced precision.
Facts About AEG Automatic Electric Airsoft Sidearms
AEG airsoft pistols or AEPs (automatic electric pistols) are also an option to bring as a sidearm on the airsoft field. These automatic electric pistols are normally powered by mini stick batteries in the gun’s grip. They work just like an AEG SMG and use pressurized air pumped through electrically cycled gearboxes, pistons, and cylinders to propel airsoft BBs out of the barrel and very quickly at that.
AEG pistol mags generally can carry about 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs right up to about 300 FPS using 0.12g airsoft BBs or about 200 to 250 FPS using 0.20g airsoft BBs. The electrical gearbox system can shoot around 700+ BBs per minute which depends on if you have enough spare mags to reload (after every 20 to 30 rounds) and the battery maintains its charge that long. These handguns can efficiently shoot airsoft BBs at around 150 foot distances.
AEG Pistol Quality and Performance
AEG pistol quality has increased substantially in the last few years. The earliest gen AEP guns were a bit sketchy and undependable, but the new models have most of the problems resolved and make efficient airsoft secondary guns. They can be modified with increased magazine storage capacities and by accommodating more powerful batteries.
A substantial benefit of using an AEG handgun is that you have the power to rewire the connections to use a more substantial battery. Depending on the AEG pistol type, you can gain a substantial increase in efficiency by employing a 2 cell Lipo battery (like an 2S Lipo) rather than the stock AEP battery.
Which Airsoft Handgun is Right for Me to Buy?
Looking for the right airsoft sidearm for you depends upon how much you can afford, how often you want to play airsoft with it, and where you hope to play. Look at a green gas blowback pistol or AEP handgun if you have $100 or more to spend on your airsoft pistol. These kinds of pistols are typically the top of the line, have good efficiency, and are usually a great gun to get. Check out a CO2 handgun or cheaper GBB handgun if you have around $50 to $100 to invest. These mid-tier guns will still get the job done and will be resilient sidearms. If you have fifty dollars or less, consider a cheap CO2 or springer handgun. You can still find a durable airsoft handgun to use for the pistol games.
