Airsoft Pistol Product Details

CO2 Smith & Wesson Sigma Pistol FPS-400 Airsoft Gun

Airsoft Pistol Product Features

This is a CO2 powered Airsoft Pistol which means that it uses CO2 Gas as a propellant. It shoots hard and fast and is extremely lifelike. One feature many CO2 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 CO2 Airsoft Pistol doesn’t require any pumping just simply point and shoot. This is a high end CO2 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 CO2 for this gun separately.

Airsoft Handgun Type Info

Learn about airsoft sidearms and handguns and how you can use them as backup weapons or as primary weapons on the airsoft playing field. Getting the ideal handgun and practicing with it can make an impact in hitting your shots. Pistols, naturally, are lower range airsoft guns. They are typically produced after authentic handguns or replications of actual pistols. A large number of airsoft handguns are completely certified releases of their actual gun counterparts. These airsoft guns can operate in the same ways and appear identically to the real guns they are designed around while blasting airsoft BBs in place of actual 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 handguns. Each of these varieties of sidearms has benefits and differences connected with them. Learning more about the types of airsoft sidearms lets you decide which type is right for you and your airsoft play style.

Details About CO2 Airsoft Pistols

CO2 airsoft handguns are one of the most popular and long lasting types of handguns. These handguns use pressurized CO2 gas to propel airsoft BBs out of the handgun barrel.

These kinds of airsoft weapons are great for playing in cooler weather conditions since the pressurized CO2 gas is less susceptible to performance decreases with temperature levels. This fact gives CO2 airsoft handguns great FPS and shot consistency while playing airsoft in the winter for example where other varieties of airsoft handguns like green gas cease to operate or barely shoot airsoft BBs.

About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft handguns are powered by common 12 gram CO2 cartridge cylinders. These cartridges resemble a shiny cylinder and contain high pressured CO2 gas composed of just one carbon atom and two oxygen atoms for this reason the molecular formula is “C + O2”.

The CO2 gas cartridges cannot be used multiple times and you can commonly order them in packs of 12, 20, 50, or 100 12 gram CO2 cartridge sets. They come sealed to retain the CO2 gas securely within, but soon after they are punctured (shooting them inside of an airsoft handgun breaks the seal) the cartridges will start to lose pressure if they are not expended. You must attempt to deplete the entire CO2 cartridge the exact same day you open the seal. Use the opportunity to do some handgun target practice and use up the rest of the excess gas if the airsoft games end and you still have CO2 gas left. There is no gas level indication on the cartridge so you have to shoot up until the pistol stops cycling.

CO2 cartridges can be stored for a while if the cylinders are kept sealed. They have a manufacturer’s best used by date normally printed on the package or cartridge cylinder, but they will probably last for a very long period of time past this date if the cartridge seals are not broken.

Green Gas Airsoft Sidearms

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

The green gas is housed in the pistol’s mag which can typically hold in-between 15 to 20+ 6mm BBs based on the gun style. A bunch of valves, silicone stoppers, and seals keep the propane gas stored in the pistol mag prior to when the handgun’s trigger is pulled. It is a good plan to top off and fill up your green gas in the pistol mag each time you load it into the handgun. Pistol-wielding airsoft players can also bring excess bottles of propane gas in the field for reloading in-between breaks in the battle or in-between missions.

When bringing a green gas handgun on the airsoft field or arena as a secondary or main weapon, additional handgun magazines are strongly recommended for quickly reloading. Having additional magazines on-hand allows you to join in the action in the middle of firefights or while clearing buildings in CQB (close quarters combat) room-to-room fights.

Green gas handguns are great for CQB at airsoft fields considering that rifles and full-sized AEGs are usually not authorized to be used for indoor engagements. This is a safety regulation because of the close quarters proximity of airsoft players during shooting engagements and the potential for players to be injured. While green gas handguns still shoot airsoft BBs at around 300 FPS, the short handgun barrel aids to keep the joules and energy moving the BB at a decreased level compared to AEGs, sniper rifles, and long guns.

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

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

About GBB and Green Gas Limitations

While green gas typically can be used extremely well on the airsoft field, it does have drawbacks. This includes when green gas guns are played with throughout the winter airsoft games in the snow or in colder weather (like lower 32 degrees F). Considering that the green gas or propane gas is stored in the weapon’s magazine using silicone seals, o-rings, and gaskets, the cold can impact these seals and make the gas to escape prior to shooting. The decrease in pressure can make the airsoft BBs to just shoot a couple of feet (like 10 feet in cold temps ) when the gun would usually shoot airsoft BBs over 100+ foot ranges in warmer temps).

One option to this issue is to keep the GBB handgun magazines warmer by placing them next to your body prior to game play. If you absolutely need to play with a reputable airsoft pistol in the cold, it might also be worth getting a CO2 variation of your favorite handgun.

Spring Airsoft Pistols

Spring airsoft handguns are powered by strong springs with irregular pitches that fire the BBs down the handgun barrel. They are generally one shot only. The manual functions of reloading, firing, and cocking spring pistols makes the fire rate much slower than CO2, green gas, and GBB pistols. When shooting at foes on the airsoft field with upgraded weapons and fully automatic airsoft AEG assault rifles, SMGs, sniper rifles, and CO2, green gas, or GBB airsoft handguns, this can make spring airsoft guns entertaining to use, however less effective.

Spring guns perform best in springer wars where airsoft players can just use comparable, single shot spring handguns or as a transitional weapon for CQB settings when you can often quietly sneak up on other airsoft opponents to get an assured one-shot-one-kill. In the latter situation, a quick 2nd follow-up shot is not really needed since the other player is now struck and out of the game play or running back to respawn. Take care when attacking a number of foes since the spring gun just shoots as quick as you can re-chamber an airsoft BB manually.

About Spring Pistol Efficiency

Spring guns are considerably reliable under the most ideal conditions. Their FPS normally chronos at around 250 FPS to 300 FPS with lighter 0.12g airsoft BBs. These pistols typically fire lighter weight airsoft BBs due to the fact that the springs are less powerful than other styles of airsoft weapons. Spring guns can typically shoot up to 120 feet or more with 0.12g BBs however precision diminishes quickly. Choosing conventional 0.20g weight airsoft BBs, you will most likely have a decreased range of around 60 to 80 feet with enhanced target accuracy.

AEG Automatic Electric Airsoft Pistols

AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a viable option to use as a secondary gun on the airsoft field. These automatic electric handguns are typically powered by mini stick batteries in the pistol’s butt. They operate similar to an AEG gun and use pressurized air with electrically cycled pistons and gearboxes to shoot airsoft BBs quickly and rapidly.

AEG pistol magazines usually can hold about 20 to 30 airsoft BBs. The pistols can fire airsoft BBs up to around 300 FPS with 0.12 gram airsoft BBs or 200 to 250 FPS using 0.20g airsoft BBs.

AEG Pistol Quality and Performance

AEG handgun quality has actually risen substantially over the last few years. The initial generations were a bit sketchy and unreliable, however the new versions have most of the bugs worked out and make efficient airsoft secondary guns. They can be improved with maximized mag storage capacities and also accommodating more powerful batteries.

A huge advantage of using an AEG pistol is that you have the ability to rewire the adapters to use a bigger battery. Depending on the AEG pistol design, you can get a large increase in efficiency by adopting a two cell Lipo battery (2S Lipo) instead of the stock mini battery.

Which Airsoft Pistol is Right for Me?

If you have $100 or more to spend on your airsoft pistol, take a look at a green gas blowback handgun or automatic electric pistol. If you have in-between fifty to one-hundred dollars to invest, look at a CO2 handgun or cheaper GBB handgun. You can still look for a resilient airsoft pistol by checking out cheaper pistols and by shopping for used pistols if you are on a budget.
