Airsoft Pistol Product Details

Green Gas KWA H&K USP Match Pistol FPS-410 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 Info

Learn about airsoft pistols and sidearms and how you can use them as backup guns or as core weapons on the airsoft playing field. Many airsoft handguns are fully manufactured and licensed releases of their real firearm equivalents and run and appear in the very same ways while shooting airsoft BBs rather than actual bullets.

There are a variety of airsoft pistols consisting of CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these varieties of pistols have negatives and positives related to them. Learning more about the types of airsoft pistols allows you to make a decision on which type is right for you and your airsoft gameplay style.

About CO2 Airsoft Handguns

CO2 airsoft handguns are among the most common and long lasting kinds of pistols. They are all season, all weather guns and function well in lots of kinds of extreme temperatures, weather and climates. These handguns use high pressure CO2 gas to propel airsoft BBs out of the gun barrel. The CO2 cartridge stores the gas and is usually stored in the gun’s handle.

These kinds of airsoft weapons are good choices for playing airsoft in cold and snowy temperatures considering that the high pressure CO2 gas is less prone to variation with low temperatures. This fact offers excellent FPS and shot consistency while playing airsoft in the winter months for example where other styles of airsoft guns like green gas cease to function or hardly fire pellets.

Info About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft pistols are powered by regular 12 gram CO2 cartridge cylinders. These cartridges resemble a metal cylinder and store high-pressure CO2 gas comprised of a single carbon atom and two oxygen atoms for this reason the molecular formula is “C + O2”.

The cartridges come sealed to keep the CO2 gas securely within, but when they are opened (firing them in an airsoft pistol breaks the seal) they will start to lose pressure if they are left unused. If the airsoft games end and you still have CO2 gas left, use the opportunity to do some handgun target practice and use up the rest of the excess gas.

CO2 cartridges have a long storage life if they are kept sealed. They do have a maker’s use by date normally printed on the package or cartridge cylinder, but they may survive for an extended period of time past this date if the cartridge seal is not tampered with.

Green Gas and Propane Airsoft Sidearms

Green gas airsoft sidearms function similarly to CO2 guns, however they do not use CO2 cartridges. Instead, they use green gas or propane for propellant to fire 6mm airsoft pellets. The operational impact on airsoft games and green gas sidearm operation is virtually the same as CO2 pistols with the guns shooting up to 300+ feet per second (FPS). Shots are quickly fired in automatic or semi-automatic shooting modes and accurate at short to mid-range ranges.

The green gas is held in the pistol’s mag that can typically hold in-between 15 to 20+ airsoft BBs based on the pistol style. A series of valves, rubber gaskets, and silicone o-rings keep the gas stored in the magazine before the handgun’s trigger is pulled.

When playing with a green gas sidearm on the airsoft field as a backup or main gun, bringing extra pistol mags is suggested for quickly reloading and engaging opponents. Having additional magazines helps you re-engage in the action in the middle of firefights or while sweeping structures in CQB (close quarters combat) room-to-room battles.

Green gas pistols are ideal for CQB at airsoft fields since rifles and full-sized AEGs are usually not allowed to be used during indoor gameplay. This is a safety standard because of the close quarters proximity of gamers during shooting engagements and potential for players to get hurt. While green gas handguns still shoot airsoft BBs at about 300 FPS, the shorter pistol barrel helps to keep the joules and energy forcing the BB lower compared to AEGs, airsoft rifles, sniper rifles, and long guns.

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

There are two various styles of green gas airsoft handguns. There are green gas blowback pistols or GBBs. These pistols function like a legitimate handgun with the gun’s slide “blowing back” and moving with every shot. The propane induces the slide to cycle each time a new airsoft BB is chambered. The result is extremely cool, however the GBB handguns usually are more expensive and likely have more to break. The green gas non-blowback airsoft handguns have a stationary slide which does not cycle. The non-blowback guns usually cost less than GBBs. Efficiency is about the same when comparing the two types of green gas handguns.

About GBB and Green Gas Limitations

While green gas usually functions effectively on the airsoft field, it does have issues. When green gas and GBB guns are used in the winter airsoft games in the snow or in cold temps (like under 32 deg F). Since the green gas or propane is stored in the weapon’s magazine by rubber seals and gaskets, cold weather can impair these seals and trigger the gas to seep out prior to firing the pistol. This can cause the airsoft BBs to only shoot a few feet (like 10 feet in cold temps ) when it would usually shoot airsoft BBs over 100+ feet in warmer temperatures).

One solution to this issue is to keep the GBB handgun mags warmer by putting them next to a heat source or by your body before game play. This can help to warm the seals, gaskets, and valves and help to seal in the green gas. It may also be worth getting a CO2 variation of your favorite pistol if you actually prefer to play airsoft with a reliable airsoft handgun in the cold. The CO2 cartridges come sealed and the gun shoots better in sub-freezing temperatures and while playing in the snow.

Spring Airsoft Sidearms

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

Spring airsoft guns perform the best in springer wars where participants can only use comparable, single shot spring pistols or as a transition weapon for CQB buildings when you can often quietly sneak up on other airsoft opponents to get a guaranteed one-shot-one-kill. In the latter circumstance, a rapid second follow-up shot isn’t called for given that the other person is now hit by the first shot and out of the gameplay or heading back to respawn. Look out when engaging multiple airsoft players considering the gun just fires as fast as you can re-chamber an airsoft BB by hand.

About Spring Pistol Efficiency

Spring handguns are really reliable under the appropriate situations. Their FPS usually chronos at about 250 FPS to 300 FPS with lighter 0.12 gram airsoft BBs. These guns usually fire the lighter weight airsoft BBs since the springs are less powerful than other types of airsoft guns like SMGs. Spring pistols can generally be accurate at up to 120 feet or more with 0.12g BBs however the ability to engage targets accurately diminishes quickly. Using conventional 0.20 gram weight airsoft BBs, you will very likely have a decreased shooting distance of about 60 to 80 feet or less with increased target accuracy.

AEG Automatic Electric Airsoft Pistols

AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a viable option to bring into the field as a backup gun on the airsoft field. These automatic electric handguns are normally powered by mini stick batteries in the gun’s grip. They function similar to an AEG SMG and use pressured air pumped through electrically cycled pistons and cylinders to shoot airsoft BBs out of the barrel and very rapidly at that.

AEG handgun mags normally can carry about 20 to 30 airsoft BBs. The handguns can launch airsoft BBs up to about 300 FPS using 0.12g airsoft BBs or 200 to 250 FPS using 0.20g airsoft BBs.

AEG Pistol Quality and Performance

AEG pistol quality has actually risen significantly over the last few years. The initial gen guns were a little bit unreliable and sketchy, but the more recent versions have the issues worked out and make reliable airsoft backup weapons. They can be modified with increased magazine capacities along with accommodating more powerful batteries.

A large benefit of using an AEG pistol is that you have the ability to rewire the battery connections to use a more substantial battery. Depending on the AEG handgun type, you can get a sizable increase in functionality by taking advantage of a two cell Lipo battery (2S Lipo) as a replacement for the stock AEP battery.

Which Airsoft Handgun is Best for Me?

If you have over one-hundred dollars to use to buy your airsoft pistol, you may want to consider a GBB pistol or automatic electric handgun. If you have between $50 to $100 to spend, evaluate a good quality CO2 handgun or more affordable GBB handgun. If you have less than $50, you can still get a durable airsoft pistol to use for the pistol games.
