Please only use .20 gram high quality BBs with this item in order to keep it in working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. You must be 18 years of age or older to purchase this Airsoft gun. You will need to purchase Green Gas for this gun separately.

How to Choose an Airsoft Handgun

Find information about airsoft pistols and handguns and how you can use them as backup weapons or as primary weapons on the airsoft playing field. Practicing your shot accuracy and getting the right sidearm can be a game changer in nailing your shots. Handguns, by nature, are diminished range airsoft guns. They are commonly crafted after firearm pistols or miniatures of actual pistols. A lot of airsoft handguns are completely certified versions of their real handgun equivalents. These airsoft guns can function (except for shooting bullets) in the same ways and visually appear identically to the real guns they are modeled after while shooting airsoft BBs rather than actual bullets.

There are a variety of airsoft sidearms including CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these styles of pistols have negatives and positives related to them. Finding out about the varieties of airsoft handguns helps you figure out which type is right for you and your airsoft game play style.

About CO2 Airsoft Pistols

CO2 airsoft pistols are one of the most heavy duty and standard varieties of pistols. They are all weather guns and operate well in many types of temperatures, weather and environments. These sidearms use high pressure CO2 gas to push airsoft BBs down the handgun barrel. The CO2 cartridge is normally kept in the handgun’s magazine inside the handle.

These forms of airsoft pistols are great for playing airsoft in cold and snowy temperatures considering that the high pressure CO2 gas is stored in the sealed cylinders and less prone to performance decreases by low temperatures. This gives CO2 airsoft guns good FPS and shot consistency while playing airsoft in the cold for example where other kinds of airsoft sidearms like green gas stop operating or hardly fire pellets.

Additional Info About CO2 Gas and CO2 Cylinders

CO2 airsoft sidearms are powered by typical 12 gram CO2 cartridges. These cartridges look similar to a metallic cylinder and store high-pressure CO2 gas composed of 1 carbon atom and two oxygen atoms for this reason the molecular formula is “C + O2”.

The CO2 gas cylinders cannot be refilled and you can normally buy them in packs of 12, 20, 50, or 100 12 gram CO2 cartridge sets. They come sealed to keep the CO2 gas safely and securely inside, but when they are punctured (firing them in an airsoft weapon breaks the cartridge seal) cartridges will begin to lose pressure if they are not expended. You ought to attempt to expend the whole CO2 cartridge the exact same day you open the seal. Use the opportunity to do some handgun 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 gun stops firing airsoft BBs.

CO2 cartridges can be stored for a longtime if the cylinders are kept sealed. They do have the maker’s use by date typically marked on the package or cartridge cylinder, but they will probably survive for a prolonged time past this date if the cartridge seal is not broken.

Green Gas Airsoft Handgun Facts

Green gas airsoft handguns are similar to CO2 pistols, but they use green gas or propane instead of CO2 cartridges. The effect on the airsoft battlefield and green gas weapon efficiency is practically the exact same as CO2 handguns with the weapons at around 300+ FPS.

The green gas is housed in the handgun’s mag and can often hold in-between 15 to 20+ BBs depending upon the pistol model. A sequence of valves, silicone gaskets, and seals keep the green gas pressurized in the magazine till the handgun’s trigger is pulled. It is a good plan to top off and fill up the propane supply in your magazine each time you reload it. Pistol-wielding airsoft players can also bring additional bottles of green gas in the field for refilling magazines in-between breaks in the battle or in-between missions.

When bringing a green gas pistol on the airsoft field as a main or secondary weapon, bringing additional handgun mags is strongly recommended for quickly reloading. Having extra magazines on-hand allows you to reengage in the action in the middle of firefights or while sweeping buildings in CQB (close quarters combat) room-to-room fights.

Green gas handguns are excellent for CQB at airsoft fields given that rifles and full-sized AEGs are usually not allowed to be used for indoor gameplay. This is an essential safety regulation because of the close quarters distance of airsoft players during shooting engagements and the potential for players to be hurt. While green gas pistols still shoot airsoft BBs at around 300 FPS, the short handgun barrel assists to keep the joules and energy moving the BB at a lower level compared to AEGs, airsoft rifles, sniper rifles, and long guns.

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

There are 2 various styles of green gas airsoft handguns. First, there are green gas blowback pistols or GBBs. These handguns run like a genuine pistol with the gun’s slide “blowing back” and cycling with every shot. The propane triggers the slide to cycle each time when a fresh airsoft BB is loaded into the chamber. The result is really cool, however the GBB pistols typically cost more and possibly have more that can break. The green gas non-blowback airsoft guns use a stationary slide which does not move. The non-blowback pistols normally cost less than GBBs. Performance is around the same when comparing the two varieties of green gas handguns.

About GBB and Green Gas Limits

While green gas normally functions extremely well, it does have limitations. This includes when they are used during the winter airsoft games in the snow or in cold weather (like under 32 degrees F). Because the green gas or propane gas is held in the pistol mag by silicone seals, o-rings, and gaskets, cold weather can negatively affect these seals and make the gas to escape before firing the pistol. The depressurized gas can make the airsoft BBs to merely shoot a few feet (like 10 feet in the cold ) when the gun would usually shoot airsoft BBs over 100+ foot ranges in warmer weather).

One strategy to this problem is to keep the GBB pistol magazines warmer by putting them next to your body, beside a heater, or inside your jacket just before the airsoft game play starts. If you absolutely desire to play with a dependable airsoft handgun in the cold weather, it may additionally be worth getting a CO2 version of your preferred pistol.

Spring Airsoft Sidearm Info

Spring airsoft guns are powered by strong springs that send the BBs out of the handgun barrel. The manual action of reloading, firing, and cocking spring pistols makes the fire rate much slower than CO2 and GBB airsoft guns.

Spring handguns perform most effectively in springer battles where participants can just use comparable, single shot spring handguns or as a close quarters backup gun for CQB settings when you can frequently surprise other airsoft opponents to get an assured one-shot-one-kill. In the latter case, a fast 2nd follow-up shot isn’t really needed since the other opponent is now hit and out of the game or heading back to respawn. Beware when engaging many different airsoft players since the gun only fires as quick as you can re-chamber an airsoft BB by hand.

About Spring Pistol Efficiency

Spring pistols are quite useful under the appropriate game conditions. Spring guns can normally shoot up to 120 feet or farther with 0.12g BBs however accuracy reduces quickly.

AEG Automatic Electric Airsoft Handguns

AEG airsoft pistols or AEPs (automatic electric pistols) are definitely a viable option to carry as a backup weapon on the airsoft field. These automatic electric pistols are commonly powered by mini stick batteries in the pistol’s grip. They operate much like an AEG SMG and use pressured air pumped through electrically cycled cylinders, pistons, and gearboxes to propel airsoft BBs out of the barrel and very rapidly at that.

AEG handgun mags usually carry around 20 to 30 airsoft BBs. The pistols can fire airsoft BBs right up to around 300 FPS when loaded with 0.12g airsoft BBs or about 200 to 250 FPS with 0.20g airsoft BBs. The electric gearbox system can shoot around 700+ BBs per minute which depends on if you have enough spare magazines to maintain the ammo supply and the battery maintains its charge that long. These AEP pistols can effectively shoot airsoft BBs at around 150 foot ranges.

AEG Handgun Quality and Performance

AEG pistol quality has actually increased substantially in recent years. The first gen guns were a bit undependable and questionable, but the newer models have the bugs worked out and make efficient airsoft secondary weapons. They can be improved with maximized magazine capacities and also accommodating larger batteries.

A large perk of buying an AEG pistol is that you have the capability to rewire the connections to use an enhanced battery. Based on the AEG pistol type, you can get a sizable output in efficiency using a 2 cell Lipo battery (2S Lipo) as opposed to the stock AEP battery. Beware of tweaking the components and the gun’s wires since you should take into account the volts, mAh, and electrical loads of the batteries. If you have customization questions, ask a qualified professional airsoft specialist at your closest airsoft shop.

Which Airsoft Sidearm is Right for Me to Play with?

Finding the ideal airsoft sidearm for you depends upon how much you can afford, how much you intend to play airsoft using it, and where you hope to play. If you have more than one-hundred dollars to invest in your airsoft pistol, consider a green gas handgun or AEG handgun. These are typically the top of the line, have the very best build qualities, and are usually a great investment. If you can afford about more than fifty but less than one-hundred dollars to use for your gun, look into a CO2 pistol or a 2nd-tier green gas pistol. Mid-tier guns like these will still do the job and are durable sidearms. Look for a cheaper CO2 or spring handgun if you have $50 or less. You can still buy a dependable airsoft handgun to use for the handgun airsoft guns.
