Airsoft Pistol Product Details

Green Gas TSD Caspian WE Hi-Capa 5.1K-TAC Pistol FPS-400 Full Metal, Blowback Airsoft Gun

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. One feature many Green Gas Airsoft Guns have is blowback, meaning that as the BB is propelled forward the slide thrusts backward mimicking the kick of a real gun! 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.

Airsoft Pistol Type Information

Learn about airsoft handguns and sidearms and how you can use them as secondary weapons or as main weapons on the airsoft playing field. Lots of airsoft handguns are completely accredited variations of their genuine pistol counterparts and look and run in the same ways while shooting airsoft BBs rather than genuine bullets.

There are a variety of airsoft pistols including CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun handguns. Each of these types of pistols come with positives and negatives related to them. Finding out about the styles of airsoft pistols lets you make a decision on which type is right for you and your airsoft gameplay style.

CO2 Airsoft Pistol Details

CO2 airsoft pistols are one of the most popular and heavy-duty types of pistols. These handguns use sealed CO2 gas cylinders to force airsoft BBs out of the pistol barrel.

These types of airsoft handguns are exceptional for playing airsoft in cold and snowy temperatures considering that the compressed CO2 gas is less vulnerable to variation by temperature. This provides very good FPS and shot consistency while playing airsoft in the wintertime for instance where other varieties of handguns like green gas stop functioning or hardly shoot pellets.

Info About CO2 Gas and CO2 Cylinders

CO2 airsoft sidearms are powered by typical 12 gram CO2 cartridges. These cartridges look similar to a metal cylinder and store high-pressure CO2 gas comprised of a single carbon atom and two oxygen atoms hence the molecular formula of “C + O2”.

The cartridges come sealed to keep the CO2 gas safely inside, but when they are opened (firing 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 chance to do some pistol target practice and use up the rest of the additional gas.

If they are kept sealed, CO2 cartridges have a long storage life. They come with a supplier’s use by date normally noted on the package or cylinder, however, they will survive for a long period past this date if the cartridge seals are not damaged.

Details About Green Gas Airsoft Pistols

Green gas airsoft pistols are comparable to CO2 pistols, however they do not use CO2 cartridges. The operational impact on the battleground and green gas weapon performance is almost the same as CO2 pistols with the guns at around 300+ FPS.

The green gas is stashed in the handgun’s mag which can usually hold around 15 to 20+ airsoft BBs based on the pistol style. A series of valves, rubber gaskets, and silicone seals keep the gas stored in the magazine up until the pistol’s trigger is pulled.

When carrying a green gas sidearm on the airsoft field as a primary or secondary gun, bringing additional mags is advised for quickly reloading and engaging the op force. Having extra magazines on-hand allows you to re-engage in the action in the course of firefights or while clearing buildings in CQB (close quarters combat) room-to-room combat.

Green gas pistols are perfect for CQB at airsoft fields since long guns and full-sized AEGs are usually not enabled to be used during indoor gameplay. This is an essential safety standard due to the close range proximity of airsoft players during shooting engagements and the potential for players to be hurt. While green gas handguns can still shoot airsoft BBs at around 300 FPS, the short handgun barrel helps to keep the joules and energy moving the BB at a decreased level compared to AEG airsoft rifles, sniper rifles, and long guns.

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

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

About GBB and Green Gas Issues

While green gas generally works effectively on the airsoft field, it does have limits. When green gas and GBB guns are used during the winter in the snow or in colder weather conditions (like under 32 degrees F). Because the green gas or propane is held in the weapon’s magazine using silicone seals, o-rings, and gaskets, cold weather can negatively impact the seals and make the gas to escape prior to shooting. The decrease in pressure can make the airsoft BBs to only shoot several feet (like 10 feet in the cold ) when it would usually shoot airsoft BBs over 100+ feet in warmer temps).

One option to this issue is to keep the GBB pistol magazines warmer by holding them next to your body, beside a heater, or inside your jacket before game play starts. If you truly need to play with a dependable airsoft handgun in the cold, it might additionally be worth getting a CO2 version of your preferred handgun.

Facts About Spring Airsoft Handguns

Spring airsoft handguns are powered by strong springs that fire the airsoft BBs down the gun barrel. They are generally single shot. The manual functioning of cocking, firing, and reloading spring airsoft guns makes the weapon’s fire rate much slower than CO2, green gas, and GBB handguns. This makes spring airsoft pistols entertaining to use, but they are usually less effective when dueling other airsoft players on the airsoft field with upgraded rifles, automatic airsoft AEG rifles, SMGs, sniper rifles, and CO2 or GBB airsoft pistols.

Spring sidearms and guns perform the best in springer wars where participants can exclusively use similar, single shot spring pistols or as a transition backup weapon for CQB buildings and MOUT sites when you can usually sneak up to other airsoft players to get an assured one-shot-one-kill. In the latter scenario, a quick 2nd followup shot is not really needed because the other opponent is already struck and out of the game play or running back to respawn. Take care when engaging a number of enemies considering the spring gun just fires as quickly as you can re-chamber an airsoft BB manually.

About Spring Pistol Performance

Spring guns are very effective under the correct situations. Spring guns like pistols can commonly shoot up to 120 feet or more with 0.12 gram BBs but accuracy decreases quickly.

AEG Automatic Electric Airsoft Pistol Details

AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a viable option to bring as a secondary gun on the airsoft field. These automatic electric pistols are normally powered by mini stick batteries in the pistol’s grip. They operate much like an AEG rifle and use pressured air with electrically cycled pistons and cylinders to shoot airsoft BBs quickly and rapidly.

AEG handgun mags typically hold around 20 to 30 airsoft BBs. The handguns can launch airsoft BBs up to around 300 FPS with 0.12 gram airsoft BBs or 200 to 250 FPS using 0.20 gram airsoft BBs.

AEG Pistol Quality and Performance

AEG handgun quality has actually grown substantially in recent years. The early generation guns were a little bit unreliable and sketchy, but the new designs have the problems resolved and make efficient airsoft backup weapons. They can be improved with maximized magazine storage capacities and by accommodating bigger batteries.

A significant perk of using an AEG handgun is that you have the capability to rewire the battery connectors to use a larger battery with longer life. Depending on the AEG pistol version, you are able to gain a substantial leap in performance using a two cell Lipo battery (like an 2S Lipo) as an alternative to the standard AEP battery. Take extra precautions when changing the components and the gun’s wires because you need to take into consideration the volts, mAh, and electrical loads of the batteries. Ask an experienced gun tech at your closest airsoft shop or store if you have customization inquiries.

What Airsoft Sidearm is Best for Me to Play with?

If you have $100 or more to use to buy your airsoft pistol, take a look at a GBB handgun or automatic electric pistol. If you have between $50 to $100 to upgrade your gun, review a good quality CO2 handgun or less expensive GBB pistol. You can still find a long lasting airsoft handgun by checking out lower end pistols and by trading with other players in the used gun market if you are looking for a deal.
