Airsoft Pistol Product Details

Green Gas KWA H&K USP 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.

How to Choose an Airsoft Handgun

Find out about airsoft guns like pistols and how you can use them as backup weapons or as primary weapons on the airsoft playing field. Practicing your accuracy and getting the ideal pistol can be a game changer in nailing your shots. Sidearms, naturally, are shorter range airsoft guns. They are generally designed after firearm pistols or replications of authentic handguns. Many airsoft sidearms are fully licensed adaptations of their actual gun counterparts. These airsoft guns can look and function (except for shooting bullets) in the same ways almost identically to the real guns they are designed around while shooting airsoft BBs rather than genuine bullets.

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

CO2 Airsoft Pistols

CO2 airsoft handguns are one of the most typical and resilient types of handguns. They are all-season weapons and operate well in many types of weather, temperatures, and climates. These sidearms use pressurized CO2 gas to shoot airsoft BBs down the weapon barrel. The CO2 cartridge is generally located in the pistol’s magazine.

These styles of airsoft weapons are great for playing airsoft in colder weather conditions considering that the compressed CO2 gas is stored in the sealed cylinders and less prone to FPS decreases with temperature. This provides good FPS and shot consistency while playing airsoft in the cold for example where other styles of pistols like green gas stop functioning or hardly shoot airsoft BBs.

Additional Info About CO2 Gas and CO2 Cartridges

CO2 airsoft sidearms are powered by standard 12 gram CO2 cylinders. These cartridges look like a chrome cylinder and hold high-pressure CO2 gas comprised of one carbon atom and a pair of oxygen atoms for this reason the molecular formula of “C + O2”.

They come sealed to keep the CO2 gas safely inside, however the moment they are opened (shooting them inside of 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 pistol target practice and use up the rest of the extra gas.

CO2 cartridges can be stored for a while if they are kept sealed. They come with a supplier’s use by date typically listed on the box or cartridge cylinder, but they will likely survive for an extended time past this date if the cartridge seal is not tampered with.

Green Gas and Propane Airsoft Sidearm Facts

Green gas airsoft sidearms are similar to CO2 pistols, however they do not use CO2 cartridges. Instead, they use green gas or propane for propellant to fire the airsoft BBs. The result on gameplay and green gas sidearm operation is virtually the same as CO2 handguns with the weapons shooting up to about 300+ feet per second (FPS). Shots are quickly fired in fully-automatic or semi-automatic shooting modes and can accurately hit targets at very short to mid-range ranges.

The green gas is held in the pistol’s magazine and can commonly hold in-between 15 to 20+ 6mm BBs depending on the handgun model. A set of valves, rubberized stoppers, and o-rings keep the propane gas pressurized in the magazine prior to when the pistol’s trigger is squeezed. It is a great habit to top off and refill your green gas supply in the pistol mag each time you reload it. Pistol-wielding airsoft players can also bring supplemental bottles of green gas or propane in the field for refilling magazines between breaks in the fight or in-between game play.

When bringing a green gas sidearm on the airsoft field or arena as a secondary or main gun, bringing extra mags is recommended for rapidly reloading. Having extra magazines on-hand helps you re engage in the action in the course of firefights or while clearing buildings in CQB (close quarters combat) room-to-room fighting.

Green gas handguns are excellent for CQB at airsoft fields given that long guns and full-sized AEGs are normally not allowed to be used for indoor game play. This is a safety standard because of the close quarters distance of players during shooting engagements and potential for players to get hurt. While green gas handguns still shoot airsoft BBs at around 300 FPS, the short handgun barrel helps to keep the joules and energy pushing the BB at a lower level compared to AEGs, sniper rifles, and long guns.

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

There are two various varieties of green gas airsoft pistols. There are green gas blowback handguns 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 Limits

While green gas normally works extremely well on the airsoft field, it does have limitations. This includes when they are used throughout the winter airsoft season in the snow or in colder temperatures (like lower 32 deg F). Since the green gas or propane is stored in the pistol mag by silicone seals, o-rings, and gaskets, low temperatures can affect these seals and cause the stored gas to seep out prior to shooting. The depressurized gas can cause the airsoft BBs to merely shoot a couple of feet (like 10 feet in the cold ) when the gun would typically shoot BBs over 100+ foot ranges in warmer temperatures).

One option to this problem is to keep the GBB pistol mags warmer by putting them next to your body prior to the airsoft game play starts. If you absolutely want to play with a reputable airsoft handgun in the cold weather, it might also be worth getting a CO2 variation of your preferred pistol.

Spring Airsoft Pistols

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

Spring sidearms work the best in springer wars where players can just use related, single shot spring weapons or as a transition backup weapon for CQB buildings and MOUT sites when you can often surprise other airsoft players to get an assured one-shot-one-kill. In the latter situation, a fast 2nd followup shot will not be needed given that the other opponent is now hit and out of the game play or running back to respawn. When engaging numerous adversaries because the springer only shoots as quick as you can re-chamber an airsoft BB by hand, be careful.

About Spring Pistol Performance

Spring pistols are extremely useful under the correct conditions during airsoft games. Spring guns can commonly shoot up to 120 feet or farther with 0.12g BBs however precision decreases rapidly.

Details About AEG Automatic Electric Airsoft Sidearms

AEG airsoft pistols or AEPs (automatic electric pistols) are definitely an option to use as a backup gun on the airsoft field. These automatic electric handguns are normally powered by mini stick batteries in the weapon’s butt. They operate similar to an AEG rifle and use pressured air forced through electrically cycled gearboxes, pistons, and cylinders to propel airsoft BBs out of the barrel and very rapidly at that.

AEG pistol mags generally store about 20 to 30 airsoft BBs. The handguns can shoot airsoft BBs approximately around 300 FPS with 0.12g airsoft BBs or 200 to 250 FPS when loaded with 0.20 gram airsoft BBs. The electrical gearbox system can shoot around 700+ 6mm BBs per minute assuming you have enough spare mags to reload the gun and the battery holds out that long. These AEP handguns can efficiently fire airsoft BBs at around 150 foot ranges.

AEG Pistol Quality and Performance

AEG handgun quality has risen significantly over the last few years. The early generation guns were a bit sketchy and undependable, however the more recent versions have most of the problems resolved and make efficient airsoft secondary weapons. They can be upgraded with increased magazine storage capacities and also accommodating more powerful batteries.

A big advantage of carrying an AEG pistol is that you have the ability to rewire the connectors to use a more substantial battery. Depending on the AEG handgun type, you can get a huge increase in performance by using a two cell Lipo battery (2S Lipo) as an alternative for the stock AEP battery.

Which Airsoft Sidearm is Right for Me to Buy?

If you have over one-hundred dollars to use to buy your airsoft handgun, take a look at a green gas blowback pistol or automatic electric pistol. If you have around $50 to $100 to spend, evaluate a CO2 handgun or cheaper GBB pistol. If your gun budget is lower, you can still get a hold of a resilient airsoft handgun to use for the handgun games.
