Airsoft Pistol Product Features

This is a Green Gas Airsoft Pistol which means that it uses Green Gas as a propellant. It shoots hard and fast and is extremely lifelike.

This Green Gas Airsoft Pistol doesn’t require any pumping just simply point and shoot. This is a high end Green Gas Airsoft gun. 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 Pick an Airsoft Pistol

Learn more about airsoft pistols and sidearms and how you can use them as backup weapons or as primary weapons on the airsoft playing field. Practicing your accuracy and getting the right handgun can make a big difference in aiming your shots. Sidearms, by nature, are diminished range airsoft guns. They are commonly made after firearm handguns or copies of legitimate handguns. Lots of airsoft handguns are completely certified releases of their genuine weapon counterparts. These airsoft guns can handle in the same ways and appear identically to the real guns they are modeled around while shooting airsoft BBs as opposed to real bullets.

There are a few types of airsoft sidearms including CO2, green gas or propane (blowback and non-blowback), spring powered, and AEG automatic electric gun handguns. Each of these varieties of sidearms has benefits and differences related to them. Finding out about the kinds of airsoft handguns lets you decide which type is right for you and your airsoft gameplay style.

Details About CO2 Airsoft Handguns

CO2 airsoft sidearms are one of the most heavy-duty and common types of handguns. They are all-season handguns and work well in lots of types of extreme temperatures, weather and environments. These sidearms use high pressure CO2 gas to send airsoft BBs down the handgun barrel. The CO2 cartridge stores the gas within the cylinder and is normally held in the handgun’s magazine in the handle.

These types of airsoft weapons are exceptional for playing in cooler temperatures because the compressed CO2 gas is less vulnerable to performance variations with low temperatures. This provides very good FPS and shot consistency while playing airsoft in the winter for instance where other types of airsoft pistols like green gas stop functioning or hardly fire BBs.

Information About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft pistols are powered by conventional 12 gram CO2 cartridges. These cartridges look similar to a metal cylinder and store high-pressure CO2 gas consisting of one carbon atom and 2 oxygen atoms hence the molecular formula is “C + O2”.

The cartridges come sealed to keep the CO2 gas securely inside, however the moment they are opened (firing them inside of an airsoft pistol breaks the cartridge seal) they will begin to lose pressure if they are left unused. If the airsoft games end and you still have CO2 gas left, use the opportunity to do some handgun target practice and use up the rest of the extra gas.

CO2 cartridges have a long storage life if they are stored sealed. They come with a manufacturer’s expiration date usually printed on the package or cylinder, however, they will maintain pressure for a very long period past this date if the cartridge seal is not tampered with.

Green Gas and Propane Airsoft Sidearm Facts

Green gas airsoft pistols function similarly to CO2 handguns, however they do not use CO2 cartridges. As an alternative, they use green gas or propane gas for propellant to propel 6mm airsoft pellets. The operational impact on airsoft games and green gas weapon effectiveness is virtually the same as CO2 handguns with the guns shooting up to about 300+ feet per second. Shots are rapidly fired in automatic or semi-automatic shooting modes and can hit targets at short to mid-range ranges.

The green gas is stored in the handgun’s magazine and can frequently hold in-between 15 to 20+ 6mm BBs depending upon the handgun design. A sequence of valves, rubber stoppers, and seals keep the propane sealed in the pistol magazine until the handgun’s trigger is pulled. It is a great habit to top off and fill up the green gas in your pistol mag each time you reload it. Pistol-wielding gamers can even take surplus bottles of green gas in the field for reloading in-between breaks in the battle or in-between game play.

When bringing a green gas sidearm on the airsoft field as a main or backup weapon, bringing additional magazines is advised for rapidly reloading and engaging the op force. Having extra magazines allows you to get back in the action during firefights or while clearing buildings in CQB (close quarters combat) room-to-room battles.

Green gas handguns are optimal for CQB at airsoft fields because rifles and full-sized AEGs are generally not approved to be used for indoor shooting. This is an essential safety rule due to the close quarters distance of players during shooting engagements. While green gas pistols can still fire airsoft BBs at about 300 FPS, the short pistol barrel aids to keep the joules and energy pushing the BB at a decreased level compared to airsoft rifles, sniper rifles, and other long guns.

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

There are 2 different styles of green gas airsoft pistols. There are green gas blowback handguns or GBBs and non-blowback pistols. The green gas non-blowback airsoft handguns have a fixed slide which does not move.

About GBB and Green Gas Limits

While green gas normally performs very well, it does have drawbacks. When they are used during the winter airsoft games in the snow or in colder temperatures (like below 32 degrees F). Considering that the green gas or propane is stored in the magazine using rubber seals, o-rings, and gaskets, cold weather can impair the seals and make the stored gas to escape before shooting. This can make the airsoft BBs to just shoot several feet (like 10 feet in cold temps ) when the pistol would typically shoot BBs over 100+ foot ranges in warmer weather conditions).

One option to fix this challenge is to try to keep the GBB pistol magazines warmer by positioning them near your body prior to game play. This can help to warm up the rubber seals and better seal in the green gas. If you definitely prefer to have fun with a reputable airsoft handgun in the cold, it may also be worth buying a CO2 version of your favorite handgun. The CO2 cylinders come sealed and these guns shoot much better in sub-freezing conditions and while playing in the snow.

About Spring Airsoft Handguns

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

Spring guns work best in springer wars where opponents can only use related, single shot spring handguns or as a transition weapon for CQB buildings when you can usually surprise other airsoft players to get an assured one-shot-one-kill. In the latter circumstance, a rapid second followup shot will not be needed due to the fact that the other opponent is already hit and out of the game or running back to respawn. Look out when attacking several opponents since the spring gun only fires as fast as you can re-chamber an airsoft BB by hand.

About Spring Pistol Effectiveness

Spring pistols are extremely reliable under the proper conditions during airsoft games. Their FPS often chronos at about 250 FPS to 300 FPS with lighter 0.12g airsoft BBs. These handguns typically fire the lighter weight airsoft BBs since the springs are less powerful than other styles of airsoft guns like rifles. Spring guns can normally shoot up to 120 feet or more with 0.12g BBs however the ability to hit targets accurately reduces quickly. Shooting normal 0.20g weight airsoft BBs, you will very likely have a shooting distance of around 60 to 80 feet or less with increased target accuracy.

Facts About AEG Automatic Electric Airsoft Handguns

AEG airsoft handguns or AEPs (automatic electric pistols) are definitely a good choice to carry as a secondary gun on the airsoft field. These automatic electric pistols are typically powered by mini stick batteries in the gun’s handle. They work just like an AEG rifle and use pressured air pumped through electrically cycled pistons, gearboxes, and cylinders to shoot airsoft BBs quickly and rapidly.

AEG pistol mags usually can carry around 20 to 30 airsoft BBs. The pistols can launch airsoft BBs up to about 300 FPS with 0.12 gram airsoft BBs or 200 to 250 FPS with 0.20g airsoft BBs.

AEG Handgun Quality and Efficiency

AEG handgun quality has increased substantially recently. The first generation guns were a bit questionable and undependable, however the newer versions have most of the deficiencies resolved and make reliable airsoft backup weapons. They can be upgraded with enhanced mag capacities together with accommodating bigger batteries.

A large benefit of using an AEG handgun is that you have the capacity to rewire the battery connectors to use an increased capacity battery. Based on the AEG pistol design, you can get a big boost in efficiency utilizing a two cell Lipo battery (2S Lipo) as an alternative to the standard battery. Beware of changing the components and the gun’s wires because you should take into consideration the volts, mAh, and electrical loads of the battery. If you have customization questions, ask a pro weapon service technician at your nearest airsoft store or shop.

What Airsoft Handgun is Right for Me to Buy?

Looking for the best airsoft sidearm for you depends upon your budget, how often you wish to play airsoft with it, and where you hope to play. Check out a green gas blowback pistol or automatic electric AEP handgun if you have more than one-hundred dollars to invest on your airsoft handgun. These guns are usually the top-tier guns, have the most effective performance, and can be a great airsoft gun to invest in. Consider a CO2 pistol or more affordable green gas GBB handgun if you have about more than $50 but less than $100 to put into an airsoft gun purchase. Middle of the road guns like these will still be fun to play with and are pretty durable sidearms. Look for a low end CO2 or spring pistol if you have less than fifty dollars. You can still get a long-lasting airsoft handgun to use for the handgun games.
