Airsoft Pistol Product Details

Spring Walther P99 Pistol Extra Kit Black FPS-300 Airsoft Gun

Airsoft Pistol Product Features

This is a Spring Airsoft Pistol, which means it’s powered by a spring and must be cocked for each shot. It’s fast, clean, inexpensive and easily maintained; it requires no gas or batteries to operate. Also, Spring Airsoft Guns are the toughest, most durable of all Airsoft Guns, because they’re made with few breakable pieces. If you’re looking for a fun, reliable Airsoft Pistol that’ll look great and perform even better, you’ve come to the right place. You must be 18 years of age or older to purchase this Airsoft gun.

Airsoft Pistol Variety Details

Find information about airsoft pistols and sidearms and how you can use them as extra weapons or as main weapons on the airsoft playing field. Lots of airsoft handguns are fully manufacturer licensed variations of their actual handgun equivalents and function and appear in the exact same ways while shooting airsoft BBs rather than authentic bullets.

There are a variety of airsoft sidearms including CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun sidearms. Each of these types of pistols have positives and negatives related to them. Learning about the varieties of airsoft sidearms lets you choose which type is right for you and your airsoft play style.

CO2 Airsoft Handgun Details

CO2 airsoft sidearms are one of the most long lasting and popular types of sidearms. These pistols use sealed CO2 gas cylinders to shoot airsoft BBs out of the weapon barrel.

These kinds of airsoft handguns are great for playing in cold and snowy weather considering that the high pressure CO2 gas is less vulnerable to performance decreases by temperature levels. This gives CO2 airsoft guns good FPS and shot consistency while playing airsoft in the winter season for example where other styles of airsoft sidearms like green gas stop performing or hardly fire airsoft BBs.

Additional Info About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft handguns are powered by typical 12 gram CO2 cartridges. These cartridges look like a shiny steel cylinder and contain high-pressure CO2 gas consisting of 1 carbon atom and 2 oxygen atoms, and so the molecular formula comes out to be “C + O2 “. These atoms are connected in the following order “O= C =O”. The gas is held in the 12 gram cylinders under extremely high pressure of about ~ 800psi which translates to 55bar.

The CO2 cylinders cannot be refilled and you can typically buy them in packs of 12, 20, 50, or 100 12 gram CO2 cartridge sets. They come sealed to preserve the CO2 gas securely inside, once they are punctured (shooting them in an airsoft gun breaks the seal) cartridges will begin to lose pressure if they are not used up. You must try to burn up the whole CO2 cartridge the very same day you open the seal. If the airsoft matches end and you still have CO2 gas leftover, use the chance to do some handgun accuracy and target practice and burn up the remainder of the excess gas. There is no gas level sign on the cartridge so you have to shoot until the gun stops shooting airsoft BBs.

CO2 cartridges have a long storage life if they are stored sealed. They come with a maker’s expiry date typically marked on the box or cartridge cylinder, however, they will maintain pressure for a very long time past this date if the cartridge seals are not damaged.

Green Gas and Propane Airsoft Handguns

Green gas airsoft pistols resemble CO2 pistols, however they do not use CO2 cartridges. Alternatively, they use green gas or propane gas for propellant to propel 6mm airsoft BBs. The impact on airsoft games and green gas weapon performance is basically the same as CO2 pistols with the guns shooting up to about 300+ feet-per-second (FPS). Shots are quickly fired in automatic or semi-automatic firing modes and can hit targets at very short to mid-range proximities.

The propane gas is stashed in the handgun’s airsoft magazine which can often hold in-between 15 to 20+ airsoft BBs based on the pistol style. A series of valves, rubberized gaskets, and seals keep the gas pressurized in the magazine before the pistol’s trigger is pulled.

When carrying a green gas handgun on the airsoft field as a secondary or main weapon, extra pistol mags are encouraged for rapidly reloading and engaging opponents. Having additional mags allows you to get back in the action in the course of firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas pistols are perfect for CQB at airsoft fields because rifles, long guns, and full-sized AEGs are usually not authorized to be used for indoor engagements. This is an essential safety rule because of the close quarters proximity of players during the shooting engagements. While green gas pistols can still fire airsoft BBs at about 300 FPS, the short pistol barrel helps to keep the joules and energy propelling the BB at a lower level compared to airsoft rifles, sniper rifles, and other long guns.

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

There are 2 various kinds of green gas airsoft pistols. First there are green gas blowback pistols or GBBs. These pistols operate like a real pistol with the pistol slide “blowing back” and cycling with every shot. The propane causes the slide to cycle each time when a fresh airsoft BB is loaded into the chamber. This effect is very cool, but the handguns typically cost more and possibly have more to break. The green gas non-blowback airsoft handguns use a stationary slide which does not move. The non-blowback weapons normally cost less than GBBs. Efficiency is about the same when comparing the two kinds of green gas pistols.

About GBB and Green Gas Limitations

Due to the fact that the green gas or propane gas is housed in the pistol magazine using rubber seals, o-rings, and silicone gaskets, cold temperatures can negatively impact these gaskets and cause the gas to escape before shooting the handgun. The decrease in pressure can make the airsoft BBs to just shoot a few feet (like 10 feet in cold temps ) when the GBB handgun would normally shoot airsoft BBs over 100+ feet in warmer weather conditions).

One solution to this problem is to try to keep the GBB pistol magazines warmer by holding them next to a heat source or by your body before game play. This can help to warm up the seals and better seal in the green gas. It may also be worth checking out a CO2 variation of your preferred handgun if you really need to play airsoft with a reliable airsoft pistol in the cold. The CO2 cylinders come sealed and perform far better in sub-freezing temps and while playing in the snow.

Spring Airsoft Sidearms

Spring airsoft pistols are powered by powerful springs that launch the BBs out of the pistol barrel. The manual action of cocking, firing, and reloading spring guns makes the fire rate much slower than CO2 and GBB pistols.

Spring sidearms perform the best in springer battles where participants can solely use related, single shot spring guns or as a transitional backup weapon for CQB buildings and MOUT sites when you can usually sneak up to other airsoft players to get a guaranteed one-shot-one-kill. In the latter situation, a rapid 2nd followup shot is not really needed given that the other opponent is now hit by the airsoft BB and out of the gameplay or going back to respawn. Look out when engaging several adversaries considering the weapon only fires as fast as you can re-chamber an airsoft BB manually.

About Spring Pistol Efficiency

Spring guns are extremely useful under the most ideal game circumstances. Their FPS generally chronos at about 250 FPS to 300 FPS with 0.12g airsoft BBs. These handguns typically fire the lighter weight airsoft BBs because the coiled springs are less powerful than other types of airsoft guns. Spring handguns can typically be accurate at up to 120 feet or more with 0.12g BBs but the ability to hit targets accurately is reduced quickly. Using normal 0.20 gram weight airsoft BBs, you will very likely have a reduced range of about 60 to 80 feet with increased accuracy.

AEG Automatic Electric Airsoft Pistol Info

AEG airsoft pistols or AEPs (automatic electric pistols) are also a viable option to use as a sidearm on the airsoft field. These automatic electric handguns are normally powered by mini stick batteries in the pistol’s butt. They work just like an AEG SMG and use compressed air pumped through electrically cycled pistons and gearboxes to propel airsoft BBs out of the barrel and rapidly.

AEG pistol magazines usually can carry about 20 to 30 airsoft BBs. The handguns can fire airsoft BBs approximately around 300 FPS with 0.12g airsoft BBs or about 200 to 250 FPS when loaded with 0.20g airsoft BBs. The electric gearbox system can shoot around 700+ BBs per minute which is estimated if you have enough spare mags to reload with and the battery lasts that long. These AEP pistols can accurately shoot airsoft BBs at around 150 foot ranges.

AEG Handgun Quality and Efficiency

AEG pistol quality has increased substantially in recent years. The first generation AEP guns were a little bit questionable and undependable, however the more recent models have most of the issues resolved and make reliable airsoft backup guns. They can be modded with enhanced mag storage capacities together with accommodating bigger batteries.

A significant perk of carrying an AEG handgun is that you have the opportunity to rewire the connectors to use a more substantial battery with higher mAh. Depending on the AEG handgun type, you can gain a large output in functionality using a 2 cell Lipo battery (2S Lipo) rather than the stock battery. Be careful with adjusting the components and wires since you should take into account the voltages, mAh, and loads of the battery. Ask a pro gun specialist at your closest airsoft shop or store if you have customization issues.

What Airsoft Pistol 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 green gas blowback handgun or automatic electric handgun. If you have in-between fifty to one-hundred dollars to buy a gun, look at a CO2 pistol or less expensive GBB handgun. You can still find a durable airsoft pistol by checking out lower end pistols and by trading with other players in the used gun market if you are trying to save money.
