Airsoft Pistol Product Details

Green Gas TSD Caspian Tactial 45 Tan 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 Handgun Style Details

Find information about airsoft sidearms and handguns and how you can use them as backup guns or as main weapons on the airsoft playing field. Getting the best handgun and practicing with it can make all the difference in hitting your shots. Handguns, naturally, are lower range airsoft guns. They are generally made after actual sidearms or models of actual handguns. Numerous airsoft sidearms are completely licensed versions of their authentic pistol equivalents. These airsoft guns can visually look and function (without shooting bullets) in the same ways almost identically to the real guns they are modeled around while blasting airsoft BBs rather than real world bullets.

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

Details About CO2 Airsoft Sidearms

CO2 airsoft pistols are among the most standard and heavy-duty styles of handguns. They are all season weapons working well in a lot of kinds of varying temperatures, weather and climates. These pistols use pressurized CO2 gas to send airsoft BBs down the weapon barrel. The CO2 cartridge stores the gas and is normally housed in the handgun’s magazine inside the handle.

These forms of airsoft guns are great choices for playing airsoft in cold and snowy weather conditions because the compressed CO2 gas is less susceptible to FPS decreases caused by low temperature. This gives CO2 airsoft guns good FPS and shot consistency while playing airsoft in the winter season for instance where other varieties of airsoft sidearms like green gas stop working or barely fire BBs.

Information About CO2 Gas and CO2 Cylinders

CO2 airsoft handguns are powered by basic 12 gram CO2 cartridge cylinders. These cartridges resemble a chrome cylinder and hold high-pressure CO2 gas comprised of 1 carbon atom and 2 oxygen atoms hence the molecular formula of “C + O2”.

They come sealed to keep the CO2 gas safely within, however as soon as they are opened (shooting them inside of an airsoft gun 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 opportunity to do some handgun target practice and use up the rest of the extra gas.

CO2 cartridges can be stored for a while if the cylinders are kept sealed. They do have the supplier’s expiration date usually listed on the box or cartridge cylinder, but they can last for an extended period of time past this date if the cartridge seals are not broken.

Details About Green Gas Airsoft Sidearms

Green gas airsoft pistols are comparable to CO2 handguns, but they use green gas or propane instead of CO2 cartridges. The result on the airsoft battlefield and green gas weapon performance is virtually the exact same as CO2 handguns with the weapons around 300+ FPS.

The green gas is held in the handgun’s grip within the magazine which can often hold roughly 15 to 20+ 6mm airsoft BBs depending upon the gun model. A series of valves, rubber stoppers, and seals keep the propane gas pressurized in the pistol mag until the handgun’s trigger is squeezed. It is a good habit to fill up and top off your green gas reserves in your pistol mag each time you reload it. Pistol-wielding players can also bring supplemental bottles of green gas in the field for refilling in-between lulls in the fight or in-between games.

When playing with a green gas handgun on the airsoft field as a backup or main weapon, bringing extra magazines is strongly recommended for quickly reloading. Having extra mags on-hand allows you to get back in the action in the course of firefights or while sweeping buildings in CQB (close quarters combat) room-to-room fighting.

Green gas handguns are perfect for CQB at airsoft fields given that rifles and full-sized AEGs are generally not permitted to be used for indoor gameplay. This is a safety standard due to the close range distance of gamers during the shooting engagements and the potential for players to be injured. While green gas handguns still shoot airsoft BBs at about 300 FPS, the short handgun barrel aids to keep the joules and energy pushing 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 types of green gas airsoft pistols. There are green gas blowback handguns or GBBs. These handguns run like an actual handgun with the pistol’s slide “blowing back” and moving with every shot. Every time a brand-new airsoft BB is loaded into the chamber, the gas causes the slide to cycle. The result is extremely cool, however the pistols frequently cost more and possibly have more that can break. The green gas non-blowback airsoft handguns have a stationary slide which does not move. The non-blowback weapons commonly cost less than GBBs. Efficiency is around the same between the two types of green gas pistols.

About GBB and Green Gas Issues

While green gas typically functions very well on the airsoft field, it does have restrictions. When green gas and GBB guns are used during the winter airsoft games in the snow or in colder temperatures (like below 32 degrees F). Because the green gas or propane gas is stored in the weapon’s magazine by silicone seals, o-rings, and gaskets, cold weather can negatively impact these seals and cause the gas to leak out before shooting airsoft BBs. The depressurized gas can cause the airsoft BBs to merely shoot a couple of feet (like 10 feet in cold temps ) when the gun would typically shoot airsoft BBs over 100+ feet in warmer weather).

One solution to this challenge is to make the GBB pistol mags warmer by putting them next to a heat source or by your body prior to airsoft game play. This can help to warm up the rubber gaskets and help to seal in the green gas. It might also be worth getting a CO2 version of your favorite pistol if you truly prefer to play with a reliable airsoft handgun in the cold. The CO2 cylinders come sealed and the gun will shoot better in sub-freezing conditions and while playing in the snow.

Spring Airsoft Sidearms

Spring airsoft sidearms are powered by strong springs with irregular pitches that launch the airsoft BBs down the gun barrel. They are usually only able to shoot one BB. The manual functions of reloading, cocking, and shooting spring guns makes the weapon’s fire rate much slower than CO2 and GBB handguns. When taking on enemies on the airsoft field with upgraded rifles, automatic airsoft AEG rifles and CO2 or GBB airsoft handguns, this makes spring airsoft guns fun to use, but less efficient.

Spring airsoft guns work most effectively in springer wars where participants can solely use similar, single shot spring pistols or as a close quarters combat backup weapon for CQB buildings when you can often surprise other airsoft game players to get a guaranteed one-shot-one-kill. In the latter circumstance, a quick 2nd follow-up shot will not be called for because the other person is already hit by the airsoft BB and out of the game or running back to respawn. Beware when fighting many different foes considering the springer just shoots as quickly as you can re-chamber an airsoft BB by hand.

About Spring Pistol Efficiency

Spring pistols are very reliable under the proper scenarios. Spring guns like pistols can normally fire up to 120 feet or farther with 0.12g BBs however the ability to hit targets decreases rapidly.

AEG Automatic Electric Airsoft Sidearms

AEG airsoft handguns or AEPs (automatic electric pistols) are also a good choice to carry as a backup gun on the airsoft field. These automatic electric handguns are normally powered by mini stick batteries in the weapon’s handle. They work much like an AEG rifle and use pressured air pumped through electrically cycled pistons, gearboxes, and cylinders to fire airsoft BBs out of the barrel and very rapidly at that.

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

AEG Handgun Quality and Efficiency

AEG handgun quality has actually grown significantly recently. The earliest generation guns were a little bit sketchy and undependable, but the newer versions have most of the bugs worked out and make efficient airsoft secondary guns. They can be upgraded with increased mag capacities as well as accommodating bigger batteries.

A substantial perk of buying an AEG pistol is that you have the opportunity to rewire the adapters to use an enhanced battery. Depending upon the AEG pistol type, you can gain a large output in performance and fire rate by using a 2 cell Lipo battery (like an 2S Lipo) as an alternative to the stock AEP battery. Take extra precautions when tweaking the parts and the gun’s wires because you have to take into account the volts, mAh, and electrical loads of the battery. If you have modding concerns, ask a pro airsoft gun service technician at your local airsoft shop.

Which Airsoft Handgun is Right for Me?

If you have over one-hundred dollars to use to buy your airsoft handgun, evaluate a GBB pistol or AEG pistol. If you have between fifty to one-hundred dollars to buy a gun, check out a CO2 handgun or cheaper GBB pistol. If your gun budget is lower, you can still choose a durable airsoft handgun to use for the handgun games.
