Airsoft Pistol Product Details

Green Gas TSD Tactical M166L 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.

Info About Airsoft Pistol Types

Learn about airsoft sidearms, pistols, and handguns and how you can use them as backup guns or as main weapons on the airsoft playing field. Numerous airsoft handguns are completely manufactured editions of their authentic gun equivalents and look and function in the very same ways while shooting airsoft BBs instead of real bullets.

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

CO2 Airsoft Pistol Details

CO2 airsoft handguns are one of the most heavy duty and standard types of pistols. These handguns use CO2 stored in small cylinders to move airsoft BBs out of the gun barrel.

These types of airsoft pistols are great for airsoft games in colder weather considering that the compressed CO2 gas is less vulnerable to performance variations with temperature. This fact gives CO2 airsoft pistols excellent FPS and shot consistency while playing airsoft in the cold weather for example where other sorts of airsoft sidearms like green gas stuffer from low performance or hardly fire airsoft BBs.

Info About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft handguns are powered by common 12 gram CO2 cartridges. These cartridges resemble a metallic cylinder and store high pressure CO2 gas comprised of just one carbon atom and two oxygen atoms for this reason the molecular formula is “C + O2”.

The CO2 cartridge cylinders are not multiple-use and you can commonly order them in packs of 12, 20, 50, or 100 12 gram CO2 cartridge sets. They come sealed to preserve the CO2 gas safely and securely within, once they are opened (firing them in an airsoft gun breaks the cartridge seal) they will start to lose pressure if they are not expended. You should try to use up the entire CO2 cartridge the same day you open the seal. Use the chance to do some pistol 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 have to shoot until the weapon stops shooting BBs.

CO2 cartridges can be stored for a while if the cylinders are stored sealed. They do have a manufacturer’s use by date normally noted on the box or cartridge cylinder, however they will likely last for a long period of time past this date if the cartridge seals are not broken.

Green Gas Airsoft Pistols

Green gas airsoft handguns function similarly to CO2 guns, but they do not use CO2 cartridges. As an alternative, they use green gas or propane for propellant to shoot 6mm airsoft BBs. The outcome on game play and green gas handgun functionality is essentially the same as CO2 pistols with the weapons shooting up to 300+ feet per second (FPS). Shots are rapidly fired in fully-automatic or semi-automatic firing modes and accurate at very short to mid-range distances.

The propane gas is kept in the handgun’s airsoft magazine that can frequently hold between 15 to 20+ airsoft BBs depending on the pistol model. A series of valves, rubber gaskets, and silicone seals keep the gas stored in the magazine until the pistol’s trigger is squeezed.

When running a green gas pistol on the airsoft field or arena as a backup or primary gun, additional handgun mags are strongly recommended for rapidly reloading and engaging the op force. Having additional mags on-hand helps you re-engage in the action in the middle of firefights or while sweeping buildings in CQB (close quarters combat) room-to-room fighting.

Green gas handguns are suitable for CQB at airsoft fields considering long guns and full-sized AEGs are normally not authorized to be used for indoor game play. This is an essential safety guideline because of the close range proximity of airsoft players during the shooting engagements. While green gas handguns can still shoot airsoft BBs at around 300 FPS, the short pistol barrel assists to keep the joules and energy shooting the BB at a decreased level compared to airsoft rifles, sniper rifles, and other long guns.

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

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

About GBB and Green Gas Issues

While green gas generally performs effectively, it does have drawbacks. When they are used over the winter in the snow or in colder weather conditions (like below 32 deg F). Given that the green gas or propane gas is kept in the weapon’s magazine using silicone seals, o-rings, and gaskets, cold temperatures can impair these seals and make the gas to leak out prior to firing the handgun. The decrease in pressure can make the airsoft BBs to just shoot a few feet (like 10 feet in the cold ) when the gun would ordinarily shoot BBs over 100+ feet in warmer temps).

One fix for this problem is to try to keep the GBB handgun mags warmer by putting them next to your body just before the game play. This can help to warm up the rubber gaskets and better seal in the green gas. It may also be worth buying a CO2 variation of your preferred handgun if you really prefer to play airsoft with a reliable airsoft pistol in the cold. The CO2 cartridges come sealed and the gun shoots better in sub-freezing conditions and while playing in the snow.

Spring Airsoft Pistol Details

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

Spring pistols work best in springer battles where players can exclusively use related, single shot spring handguns or as a transitional backup weapon for CQB environments when you can usually surprise other airsoft participants to get a guaranteed one-shot-one-kill. In the latter case, a fast second followup shot will not be really needed since the other player is now hit by the first shot and out of the game play or moving back to respawn. When engaging several airsoft players because the springer simply shoots as quick as you can re-chamber an airsoft BB manually, be careful.

About Spring Pistol Efficiency

Spring handguns are quite useful under the appropriate conditions during airsoft games. Spring guns like pistols can typically shoot accurately up to 120 feet or more with 0.12g BBs however the ability to hit targets reduces quickly.

AEG Automatic Electric Airsoft Handguns

AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a viable option to carry as a secondary gun on the airsoft field. These automatic electric handguns are commonly powered by mini stick batteries in the pistol’s handle. They operate just like an AEG rifle and use pressured air pumped through electrically cycled gearboxes and cylinders to propel airsoft BBs quickly and very rapidly at that.

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

AEG Handgun Quality and Efficiency

AEG pistol quality has actually risen significantly in recent years. The first gens were a bit undependable and sketchy, but the newer models have the issues resolved and make effective airsoft backup guns. They can be upgraded with maximized magazine capacities as well as accommodating more powerful batteries.

A big perk of buying an AEG pistol is that you have the capacity to rewire the battery connectors to use a larger battery with higher mAh. Based on the AEG handgun design, you are able to gain a big leap in performance utilizing a 2 cell Lipo battery (2S Lipo) as opposed to the standard battery. Take extra precautions when changing the components and the gun’s wires because you need to take into account the voltages, mAh, and loads of the battery. Ask a pro airsoft gun tech at your local airsoft shop if you have customization problems.

What Airsoft Handgun is Best for Me?

Picking the best airsoft pistol for you depends upon how much you want to spend, how much you intend to play airsoft using it, and where you hope to play. Consider a GBB green gas pistol or AEP pistol if you have over $100 to invest on your airsoft handgun. These kinds of guns are normally the top-tier guns, have the most effective efficiency, and are usually a pretty good airsoft gun to invest in. If you can afford about more than $50 but less than $100 to use for your gun, check out a CO2 handgun or less expensive green gas blowback pistol. These guns will still work well and will be durable sidearms. Look for a lower end CO2 or spring handgun if you have fifty dollars or less. You can still buy a strong airsoft handgun to use for the pistol games.
