Airsoft Pistol Product Details

Green Gas TSD Tactical M166 Pistol FPS-390 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.

Information on the Varieties of Airsoft Pistols

Find information about airsoft pistols and sidearms and how you can use them as extra weapons or as core weapons on the airsoft playing field. A large number of airsoft pistols are fully licensed variations of their genuine pistol counterparts and look and function in the exact same ways while shooting airsoft BBs instead of authentic bullets.

There are a number of kinds of airsoft pistols including CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun sidearms. Each of these forms of handguns have negatives and positives related to them. Learning more about the styles of airsoft pistols lets you make a decision on which type is right for you and your airsoft play style.

Details About CO2 Airsoft Pistols

CO2 airsoft sidearms are one of the most long lasting and popular types of sidearms. These handguns use CO2 stored in small cylinders to force airsoft BBs out of the gun barrel.

These styles of airsoft pistols are great for playing in cold and snowy weather conditions given that the high pressure CO2 gas is stored in the sealed cylinders and less vulnerable to performance variations caused by low temperature. This fact provides very good FPS and shot consistency while playing airsoft in the winter for instance where other kinds of airsoft pistols like green gas stop performing or hardly fire pellets.

Information About CO2 Gas and CO2 Cartridges

CO2 airsoft handguns are powered by basic 12 gram CO2 cartridge cylinders. These cartridges look similar to a shiny steel cylinder and hold high-pressure CO2 gas consisting of a single carbon atom and two oxygen atoms, and so the molecular formula of “C + O2 “. These atoms are bound in the following alignment “O= C =O”. The gas is held in the 12 gram cartridge cylinders under extremely high pressure of about ~ 800psi which correlates to 55bar.

The CO2 cartridges cannot be refilled and you can normally buy them in packs of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to keep the CO2 gas safely and securely within, once they are opened (shooting them in an airsoft gun breaks the cartridge seal) they will start to lose pressure if they are not expended. You must try to run through the whole CO2 cartridge the very 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 extra gas. There is no gas level indication on the cartridge so you have to shoot until the handgun stops firing BBs.

If they are kept sealed, CO2 cartridges can be stored for a longtime. They come with a maker’s expiry date typically marked on the package or cartridge cylinder, however they may stay pressurized for a prolonged period past this date if the cartridge seals are not broken.

Info About Green Gas Airsoft Pistols

Green gas airsoft handguns are similar to CO2 handguns, but they use green gas instead of CO2 cartridges. The impact on the battleground and green gas weapon performance is practically the same as CO2 handguns with the weapons shooting up to 300+ FPS.

The propane gas is held in the handgun’s airsoft mag which can frequently hold around 15 to 20+ airsoft BBs based on the handgun model. A series of valves, rubber gaskets, and o-rings keep the gas stored in the magazine until the handgun’s trigger is pulled.

When bringing a green gas handgun on the airsoft field or arena as a primary or secondary gun, bringing extra mags is highly recommended for quickly reloading and getting back into the game. Having extra magazines allows you to reengage in the action throughout firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas pistols are excellent for CQB at airsoft fields considering rifles and full-sized AEGs are generally not enabled to be used during indoor shooting. This is an essential safety rule because of the close range distance of gamers during the shooting engagements. While green gas handguns can still fire airsoft BBs at about 300 FPS, the shorter pistol barrel assists to keep the joules and energy moving the BB at a decreased level compared to AEGs, airsoft rifles, sniper rifles, and long guns.

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

There are two different forms of green gas airsoft pistols. First there are green gas blowback handguns or GBBs. These guns work like a realistic handgun with the slide “blowing back” with every shot. Every time a fresh airsoft BB is loaded into the chamber, the gas causes the slide to cycle. The result is very cool, but the handguns typically cost more and likely have more that can break. The green gas non-blowback airsoft guns use a fixed slide which does not move. The non-blowback weapons commonly cost less than GBBs. Efficiency is around the same when comparing the two types of green gas pistols.

About GBB and Green Gas Limits

While green gas typically functions effectively on the airsoft field, it does have limits. For example, when they are used throughout the winter season in the snow or in colder temperatures (like under 32 degrees F). Considering that the green gas or propane gas is kept in the pistol mag by silicone seals and gaskets, low temperatures can affect these seals and cause the stored gas to seep out prior to shooting airsoft BBs. The depressurized gas can cause the airsoft BBs to merely shoot a couple of feet (like 10 feet in the cold ) when the gun would ordinarily shoot BBs over 100+ foot distances in warmer temps).

One fix for this problem is to try to keep the GBB pistol magazines warmer by putting them next to your body prior to game play. This can help to warm the seals, gaskets, and valves and better seal in the green gas. It may also be worth buying a CO2 variation of your preferred handgun if you truly prefer to play with a reputable airsoft handgun in the cold. The CO2 cylinders come sealed and the gun will shoot much better in sub-freezing temps and while playing in the snow.

Facts About Spring Airsoft Sidearms

Spring airsoft handguns are powered by powerful coil springs that propel the airsoft BBs down the gun barrel. They are normally one shot. The manual action of firing, reloading, and cocking spring airsoft guns makes the weapon’s fire rate much slower than CO2, green gas, and GBB pistols. When dueling enemies on the airsoft field with upgraded rifles like fully auto airsoft AEG SMGs, sniper rifles, and CO2 or GBB airsoft handguns, this can make spring guns fun to use, however less effective.

Spring guns perform most effectively in springer battles where airsoft players can only use related, single shot spring guns or as a transitional backup weapon for CQB buildings when you can usually quietly sneak up on other airsoft players to get an assured one-shot-one-kill. In the latter situation, a fast 2nd followup shot will not be called for due to the fact that the other opponent is already hit by the first BB and out of the gameplay or headed back to respawn. Beware when fighting many different airsoft players considering the spring airsoft gun only fires as quickly as you can re-chamber an airsoft BB by hand.

About Spring Handgun Effectiveness

Spring guns are extremely useful under the right game conditions. Their FPS often chronos at around 250 FPS to 300 FPS with lighter weight 0.12g airsoft BBs. These guns usually fire lighter weight airsoft BBs since the coiled springs are less effective than other styles of airsoft guns like rifles. Spring handguns can usually shoot up to 120 feet or more with 0.12 gram BBs however precision reduces rapidly. Choosing regular 0.20 gram weight airsoft BBs, you will most likely have a decreased range of around 60 to 80 feet with improved precision.

Info on AEG Automatic Electric Airsoft Handguns

AEG airsoft pistols or AEPs (automatic electric pistols) are also a viable option to bring as a backup gun on the airsoft field. These automatic electric pistols are normally powered by mini stick batteries in the pistol’s butt. They operate much like an AEG rifle and use forced air pumped through electrically cycled cylinders and gearboxes to shoot airsoft BBs quickly and rapidly.

AEG handgun mags generally can hold around 20 to 30 airsoft BBs. The handguns can shoot airsoft BBs up to about 300 FPS with 0.12g airsoft BBs or 200 to 250 FPS with 0.20g airsoft BBs.

AEG Pistol Quality and Performance

AEG handgun quality has actually risen considerably in recent years. The first generation guns were a little bit sketchy and undependable, but the newer designs have the issues resolved and make efficient airsoft secondary guns. They can be further modified with maximized magazine storage capacities together with accommodating more powerful batteries.

A large perk of buying an AEG pistol is that you have the ability to rewire the connections to use a bigger battery. Depending on the AEG pistol type, you may be able to get a sizable boost in performance utilizing a two cell Lipo battery (2S Lipo) in place of the stock mini battery. Take care of changing the elements and the gun’s wires since you should consider the volts, mAh, and electrical loads of the battery. If you have modding concerns, ask an experienced airsoft tech at your local airsoft shop.

Which 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 pistol or AEG handgun. If you have in-between fifty to one-hundred dollars to upgrade your gun, look at a good quality CO2 pistol or less expensive GBB handgun. If you are on a budget, you can still get a hold of a resilient airsoft pistol to use for the pistol games.
