Airsoft Pistol Product Details

Green Gas Walther P99 FS Pistol FPS-415 Non-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 Styles

Learn more about airsoft pistols and how you can use them as backup guns or as primary weapons on the airsoft playing field. Getting the best sidearm and practicing with it can be a game changer in hitting your shots. Sidearms, naturally, are shorter range airsoft guns. They are most often made after genuine sidearms or copies of real handguns. Many airsoft pistols are completely licensed editions of their actual pistol equivalents. These airsoft guns can run in the same ways and visually appear almost identically to the real guns they are modeled around while blasting airsoft BBs instead of authentic bullets.

There are a variety of airsoft handguns such as CO2, green gas or propane (blowback and non-blowback), spring powered, and AEG automatic electric gun pistols. Each of these forms of pistols come with benefits and differences associated with them. Learning about the styles of airsoft handguns lets you decide which type is right for you and your airsoft play style.

About CO2 Airsoft Pistols

CO2 airsoft pistols are among the most standard and tough types of pistols. They are all-weather guns and work well in many types of weather, temperatures, and environments. These sidearms use pressurized CO2 gas to launch airsoft BBs down the gun barrel. The CO2 cartridge stores the gas within the cylinder and is usually kept in the pistol’s mag inside the handle.

These types of airsoft guns are good choices for playing airsoft in cooler weather due to the fact that the pressurized CO2 gas is stored in the sealed cylinders and less sensitive to performance decreases caused by low temperatures. This offers excellent FPS and shot consistency while playing airsoft in the winter for instance where other styles of airsoft guns like green gas stuffer from low performance or hardly shoot BBs.

Info About CO2 Gas and CO2 Cylinders

CO2 airsoft sidearms are powered by regular 12 gram CO2 cylinders. These cartridges resemble a shiny metallic cylinder and contain high-pressure CO2 gas made up of 1 carbon atom and a pair of oxygen atoms hence the molecular formula of “C + O2”.

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

If they are kept sealed, CO2 cartridges have a long storage life. They come with the maker’s best used by date typically listed on the box or cylinder, however, they can last for a very long period past this date if the cartridge seal is not broken.

Green Gas and Propane Airsoft Pistol Facts

Green gas airsoft sidearms function similarly to CO2 pistols, but they do not use CO2 cartridges. Alternatively, they use green gas or propane gas for propellant to propel the airsoft pellets. The effect on game play and green gas sidearm operation is practically the same as CO2 pistols with the guns shooting up to about 300+ feet-per-second (FPS). Shots are rapidly fired in semi-automatic or fully-automatic firing modes and accurate at very short to mid-range proximities.

The propane is held in the pistol’s airsoft magazine which can typically hold between 15 to 20+ airsoft BBs depending on the pistol type. A series of valves, rubber gaskets, and silicone seals keep the gas stored in the mag up until the handgun’s trigger is pulled.

When bringing a green gas sidearm on the airsoft field as a backup or primary gun, extra pistol mags are encouraged for quickly reloading. Having additional mags allows you to re engage in the action during firefights or while sweeping structures in CQB (close quarters combat) room-to-room combat.

Green gas handguns are perfect for CQB at airsoft fields because rifles, long guns, and full-sized AEGs are generally not allowed to be used during indoor engagements. This is an essential safety regulation due to the close quarters distance of airsoft players during shooting engagements. While green gas handguns can still fire airsoft BBs at around 300 FPS, the shorter pistol barrel aids to keep the joules and energy shooting the BB at a decreased level compared to AEGs, sniper rifles, and other long guns.

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

There are two different forms of green gas airsoft handguns. There are green gas blowback handguns or GBBs. These handguns function like an authentic handgun with the gun’s slide “blowing back” with every shot. Every time a fresh airsoft BB is chambered, the gas triggers the slide to cycle. The result is really cool, but the pistols typically cost more and likely have more parts that can break. The green gas non-blowback airsoft pistols have a stationary slide which does not cycle. The non-blowback pistols normally cost less than GBBs. Performance is about the same between the two types of green gas handguns.

About GBB and Green Gas Issues

Because the green gas or propane is kept in the pistol magazine by rubber o-rings, seals, and silicone gaskets, cold temps can negatively affect these o-rings and cause the stored gas to leak out before shooting the gun. This can make the airsoft BBs to merely land a couple of feet (like 10 feet in cold weather ) when the handgun would typically shoot airsoft BBs over 100+ foot distances in warmer temperatures).

One fix for this issue is to keep the GBB pistol mags warmer by placing them next to a heater or by your body just before the airsoft game play. This can help to warm up the seals and valves and better seal in the green gas. It may also be worth getting a CO2 variation of your favorite pistol if you truly want to play with a reputable airsoft handgun in the cold. The CO2 cartridges come sealed and these guns shoot much better in sub-freezing conditions and while playing in the snow.

Spring Airsoft Handguns

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

Spring sidearms work best in springer battles where participants can only use related, single shot spring handguns or as a close quarters backup gun for CQB buildings when you can usually surprise other airsoft players to get a guaranteed one-shot-one-kill. In the latter scenario, a rapid 2nd follow-up shot will not be called for because the other player is already hit by the first shot and out of the game play or headed back to respawn. Beware when engaging many different adversaries given that the weapon just shoots as quick as you can re-chamber an airsoft BB manually.

About Spring Pistol Efficiency

Spring guns are extremely effective under the best conditions during games. Their FPS typically chronos at around 250 FPS to 300 FPS with lighter weight 0.12 gram airsoft BBs. These pistols normally fire lighter weight airsoft BBs due to the fact that the springs are less powerful than other types of airsoft guns like rifles. Spring handguns can normally shoot up to 120 feet or more with 0.12g BBs but the ability to hit targets accurately is reduced rapidly. Using regular 0.20 gram weight airsoft BBs, you will probably have a decreased shooting distance of around 60 to 80 feet with increased target accuracy.

AEG Automatic Electric Airsoft Handguns

AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a viable option to bring into the field as a backup weapon on the airsoft field. These automatic electric pistols are normally powered by mini stick batteries in the gun’s handle. They function just like an AEG rifle and use pressured air with electrically cycled cylinders, pistons, and gearboxes to fire airsoft BBs quickly and very quickly at that.

AEG handgun mags typically can carry around 20 to 30 airsoft BBs. The handguns can fire airsoft BBs up to about 300 FPS with 0.12 gram airsoft BBs or 200 to 250 FPS using 0.20g airsoft BBs.

AEG Pistol Quality and Performance

AEG pistol quality has actually grown substantially in the last few years. The initial generations were a little bit undependable and questionable, however the newer designs have the issues worked out and make effective airsoft backup guns. They can be upgraded with maximized magazine storage capacities along with accommodating bigger batteries.

A huge advantage of carrying an AEG handgun is that you have the ability to rewire the adapters to use a more robust battery with higher mAh. Depending on the AEG pistol style, you can gain a sizable jump in performance utilizing a 2 cell Lipo battery (2S Lipo) as an alternative to the stock AEP battery. Take care of customizing the parts and wires since you should consider the volts, mAh, and electrical loads of the batteries. If you have customization questions, ask a professional airsoft service technician at your local airsoft shop or store.

What Airsoft Pistol is Best for Me?

Selecting the right airsoft handgun for you depends on how much you can afford, how often you want to play airsoft using it, and where you plan to play. Look at a GBB green gas pistol or automatic electric AEP handgun if you have $100 or more to invest on your airsoft handgun. These guns are normally the top of the line, have good performance, and are usually a pretty good gun to invest in. If you can afford around $50 to $100 to devote to your airsoft gun purchase, look at a CO2 pistol or a less expensive green gas handgun. Mid-tier guns like these will still do the job and will be tough sidearms. If you have $50 or less, research a cheap CO2 or springer handgun. You can still get a tough airsoft handgun to use for the pistol airsoft guns.
