Airsoft Pistol Product Details

Green Gas KWA H&K MK23 USSOCOM Pistol FPS-440 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 Pistol Design Additional Info

Find out about airsoft handguns and how you can use them as backup weapons or as main weapons on the airsoft playing field. Practicing your shot accuracy and getting the ideal handgun can make an impact in blasting your shots. Pistols, by nature, are much shorter range airsoft weapons. They are frequently manufactured after authentic handguns or replicas of actual pistols. A lot of airsoft sidearms are fully certified variations of their actual pistol equivalents. These airsoft guns can look and function (except for shooting bullets) in the same ways identically to the real guns they are modeled around while blasting airsoft BBs rather than real-world bullets.

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

About CO2 Airsoft Sidearms

CO2 airsoft sidearms are one of the most sturdy and typical types of handguns. These handguns use sealed CO2 gas cylinders to launch airsoft BBs out of the gun barrel.

These styles of airsoft handguns are great choices for airsoft games in cold and snowy weather because the high pressure CO2 gas is stored in the sealed cylinders and less susceptible to performance variations by temperature levels. This provides good FPS and shot consistency while playing airsoft in the cold for example where other kinds of airsoft pistols like green gas stop functioning or hardly shoot BBs.

Info About CO2 Gas and CO2 Cartridges

CO2 airsoft pistols are powered by common 12 gram CO2 cartridge cylinders. These cartridges resemble a shiny metallic cylinder and contain high-pressure CO2 gas composed of just one carbon atom and a pair of oxygen atoms hence the molecular formula is “C + O2”.

They come sealed to keep the CO2 gas securely within, but as soon as they are opened (shooting them inside of an airsoft weapon breaks the cartridge seal) they will begin to lose pressure if they are left unused. If the airsoft matches end and you still have CO2 gas left, use the opportunity to do some pistol target practice and use up the rest of the extra gas.

If they are kept sealed, CO2 cartridges can be stored for a while. They are made with the maker’s expiry date typically printed on the box or cartridge, however, they can maintain pressure for a prolonged time past this date if the cartridge seals are not punctured.

Info About Green Gas Airsoft Handguns

Green gas airsoft pistols are similar to CO2 handguns, however they use green gas instead of CO2 cartridges. The operational impact on the battleground and green gas weapon performance is almost the exact same as CO2 pistols with the guns shooting up to 300+ FPS.

The green gas is held in the handgun’s mag which can often hold around 15 to 20+ 6mm BBs depending on the pistol model. A series of valves, rubber stoppers, and seals keep the green gas sealed in the pistol mag up until the pistol’s trigger is squeezed. It is a good plan to top off and refill your green gas reserves in your pistol mag each time you load it into the pistol. Pistol-wielding airsoft players can also carry supplemental bottles of propane in the field for refilling between lulls in the fight or between gameplay.

When running a green gas handgun on the airsoft field as a backup or main gun, bringing extra pistol mags is recommended for quickly reloading and engaging opponents. Having additional magazines on-hand helps you reengage 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 suitable for CQB at airsoft fields since rifles and full-sized AEGs are usually not permitted to be used for indoor game play. This is a safety rule due to the close range proximity of gamers during the shooting engagements and the potential for players to be hurt. While green gas pistols can still shoot airsoft BBs at around 300 FPS, the shorter pistol barrel aids to keep the joules and energy launching the BB at a decreased level compared to AEG airsoft rifles, sniper rifles, and long guns.

Thinking 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. These guns function like a real pistol with the slide “blowing back” and moving with every shot. Each time a fresh airsoft BB is loaded into the chamber, the gas triggers the slide to cycle. This effect is very cool, but the weapons frequently cost more and likely have more to break. The green gas non-blowback airsoft handguns have a fixed slide which does not cycle. The non-blowback handguns normally cost less than GBBs. Efficiency is around the same between the two varieties of green gas pistols.

About GBB and Green Gas Limitations

While green gas typically performs very well on the airsoft field, it does have drawbacks. When green gas and GBB guns are used over the winter airsoft games in the snow or in cold weather (such as below 32 deg F). Because the green gas or propane gas is stored in the weapon’s magazine using rubber seals and gaskets, cold temperatures can negatively affect the seals and allow the stored gas to seep out prior to shooting airsoft BBs. The depressurized gas can make the airsoft BBs to just shoot a few feet (like 10 feet in the cold ) when it would usually shoot BBs over 100+ foot ranges in warmer temperatures).

One fix for this problem is to make the GBB pistol mags warmer by positioning them inside your jacket next to your body prior to airsoft game play. This can help to warm up the seals and valves and better seal in the green gas. It can also be worth getting a CO2 variation of your favorite pistol if you really prefer to play airsoft with a reputable airsoft handgun in the cold. The CO2 cylinders come sealed and these guns shoot far better in sub-freezing temperatures and while playing in the snow.

Facts About Spring Airsoft Sidearms

Spring airsoft pistols are powered by powerful coil springs that launch the BBs down the handgun barrel. They are typically single shot. The manual functions of shooting, cocking, and reloading spring handguns makes the weapon’s fire rate much slower than CO2 and GBB pistols. This makes spring guns entertaining to use, however they are less efficient when running into players on the airsoft field with upgraded airsoft guns, automatic airsoft AEG SMGs, sniper rifles, and CO2 or GBB airsoft handguns.

Spring guns work the best in springer wars where opponents can only use related, single shot spring weapons or as a transitional backup weapon for CQB buildings when you can frequently surprise other airsoft opponents to get a guaranteed one-shot-one-kill. In the latter case, a fast second follow-up shot will not be really needed given that the other person is now hit and out of the gameplay or running back to respawn. Be careful when fighting multiple adversaries considering the spring airsoft gun just fires as quickly as you can re-chamber an airsoft BB by hand.

About Spring Handgun Effectiveness

Spring pistols are really reliable under the correct game circumstances. Spring guns can typically shoot accurately up to 120 feet or more with 0.12 gram BBs but the ability to hit targets reduces rapidly.

AEG Automatic Electric Airsoft Pistols

AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a good choice to use as a backup weapon on the airsoft field. These automatic electric pistols are typically powered by mini stick batteries in the pistol’s butt. They function much like an AEG rifle and use forced air pumped through electrically cycled gearboxes and cylinders to propel airsoft BBs quickly and very rapidly at that.

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

AEG Handgun Quality and Efficiency

AEG pistol quality has actually grown considerably over the last few years. The earliest generation AEP guns were a bit undependable and questionable, but the newer versions have the bugs worked out and make effective airsoft backup weapons. They can be further modded with increased mag storage capacities along with accommodating more powerful batteries.

A substantial perk of carrying an AEG pistol is that you have the capability to rewire the connections to use a more robust battery with higher mAh. Depending upon the AEG pistol version, you can gain a sizable jump in performance utilizing a two cell Lipo battery (2S Lipo) rather than the standard AEP battery. Beware of modifying the elements and the gun’s wires since you have to take into account the volts, mAh, and electrical loads of the battery. If you have modding concerns, ask an expert airsoft specialist at your nearest airsoft shop or store.

What Airsoft Pistol is Best for Me to Buy?

If you have $100 or more to spend on your airsoft pistol, take a look at a green gas blowback pistol or AEG handgun. If you have in-between fifty to one-hundred dollars to shell out, check out a CO2 pistol or less expensive GBB handgun. You can still play with a resilient airsoft pistol by checking out cheaper pistols and by trading with players selling used airsoft pistols if you need to save money.
