Green Gas H&K USP Compact FPS-400 Blowback Airsoft Pistol
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 Additional Info
Find info about airsoft sidearms and handguns and how you can use them as backup guns or as main weapons on the airsoft playing field. Practicing your shot accuracy and getting the best sidearm can make a big difference in nailing your shots. Sidearms, by nature, are much shorter range airsoft weapons. They are commonly designed after real world guns or clones of real handguns. Numerous airsoft pistols are completely certified versions of their real weapon counterparts. These airsoft guns can run in the same ways and look almost identically to the real guns they are modeled around while blasting airsoft BBs as opposed to genuine bullets.
There are a number of types of airsoft pistols consisting of CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these varieties of handguns come with negatives and positives related to them. Learning about the varieties of airsoft pistols allows you to choose which type is right for you and your airsoft play style.
Details About CO2 Airsoft Handguns
CO2 airsoft pistols are one of the most popular and tough types of pistols. These pistols use CO2 stored in small cylinders to move airsoft BBs out of the weapon barrel.
These forms of airsoft weapons are exceptional for playing airsoft in colder weather because the compressed CO2 gas is less prone to variation caused by low temperatures. This gives CO2 airsoft pistols great FPS and shot consistency while playing airsoft in the winter for instance where other types of sidearms like green gas stop working or hardly fire BBs.
Info About CO2 Gas and CO2 Cartridge Cylinders
CO2 airsoft pistols are powered by common 12 gram CO2 cylinders. These cartridges look similar to a chrome metal cylinder and contain high pressure CO2 gas composed of just one carbon atom and two oxygen atoms, subsequently the molecular formula comes out to be “C + O2 “. These atoms are bonded in the following sequence “O= C =O”. The gas is stored in the 12 gram cartridge cylinders under very high pressure of approximately ~ 800psi that translates to 55bar.
The cartridges come sealed to keep the CO2 gas securely inside, however once they are opened (firing them in an airsoft handgun breaks the cartridge seal) they will begin to lose pressure if they are left unused. If the airsoft games end and you still have CO2 gas left, use the chance to do some pistol target practice and use up the rest of the remaining gas.
If they are kept sealed, CO2 cartridges have a long storage life. They do have the supplier’s expiry date typically marked on the package or cartridge cylinder, however, they may maintain pressure for a prolonged period of time past this date if the cartridge seal is not punctured.
Info About Green Gas Airsoft Pistols
Green gas airsoft sidearms function similarly to CO2 pistols, but they do not use CO2 cartridges. Alternatively, they use green gas or propane for propellant to propel the airsoft BBs. The outcome on gameplay and green gas sidearm performance is practically the same as CO2 handguns with the guns shooting up to 300+ feet per second. Shots are rapidly fired in fully-automatic or semi-automatic shooting modes and accurate at shorter to mid-range ranges.
The green gas is stored in the handgun’s airsoft mag which can often hold between 15 to 20+ BBs depending on the pistol style. A series of valves, rubber gaskets, and silicone o-rings keep the gas stored in the mag before the pistol’s trigger is squeezed.
When carrying a green gas handgun on the airsoft field or arena as a primary or backup gun, bringing extra handgun magazines is advised for rapidly reloading and getting back into the game. Having additional magazines on-hand allows you to re-engage in the action during firefights or while clearing structures in CQB (close quarters combat) room-to-room battles.
Green gas pistols are excellent for CQB at airsoft fields given that long guns and full-sized AEGs are generally not approved to be used during indoor game play. This is a safety standard due to the close range proximity of airsoft players during shooting engagements and the potential for players to be hurt. While green gas handguns can still shoot airsoft BBs at around 300 FPS, the short pistol barrel aids to keep the joules and energy launching the BB lower compared to airsoft rifles, sniper rifles, and other long guns.
About Green Gas Blowback (GBB) VS Green Gas Non-blowback
There are two different varieties of green gas airsoft pistols. There are green gas blowback handguns or GBBs. These guns operate like an authentic pistol with the pistol slide “blowing back” and cycling with every shot. The propane induces the slide to cycle every time when a brand-new airsoft BB is loaded into the chamber. This functioning while shooting is really cool, however the weapons often are more expensive and likely have more that can break. The green gas non-blowback airsoft guns have a stationary slide which does not cycle. The non-blowback handguns usually cost less than GBBs. Efficiency is about the same between the two varieties of green gas pistols.
About GBB and Green Gas Limits
Since the green gas or propane is stored in the mag by using rubber seals, o-rings, and silicone gaskets, the cold can influence these seals and allow the gas to escape prior to shooting the gun. The decrease in pressure can cause the airsoft BBs to merely shoot a couple of feet (like 10 feet in cold temps ) when the GBB handgun would usually shoot airsoft BBs over 100+ foot distances in warmer temps).
One option to fix this challenge is to try to keep the GBB pistol magazines warmer by positioning them next to a heat source or by your body just before the game play. This can help to warm up the seals and valves and better seal in the green gas. It might also be worth buying a CO2 variation of your preferred handgun if you really need to play with a trustworthy airsoft handgun in the cold. The CO2 cylinders come sealed and the gun will shoot better in sub-freezing temperatures and while playing in the snow.
Spring Airsoft Handguns
Spring airsoft guns are powered by strong springs with irregular pitches that send the BBs out of the gun barrel. The manual actions of firing, reloading, and cocking spring guns makes the fire rate much slower than CO2, green gas, and GBB handguns.
Spring sidearms and guns work most effectively in springer battles where players can just use similar, single shot spring handguns or as a transitional backup weapon for CQB buildings and MOUT sites when you can often sneak up to other airsoft opponents to get a guaranteed one-shot-one-kill. In the latter situation, a rapid second followup shot is not required given that the other person is already hit and out of the game or heading back to respawn. Look out when fighting many different players because the spring gun just fires as quick as you can re-chamber an airsoft BB by hand.
About Spring Handgun Performance
Spring pistols are extremely efficient under the most ideal game circumstances. Spring guns like pistols can usually shoot up to 120 feet or more with 0.12 gram BBs but the ability to hit targets reduces rapidly.
AEG Automatic Electric Airsoft Handguns
AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely an option to bring as a secondary weapon on the airsoft field. These automatic electric handguns are typically powered by mini stick batteries in the pistol’s grip. They operate similar to an AEG rifle and use pressured air with electrically cycled gearboxes and cylinders to fire airsoft BBs out of the barrel and very rapidly at that.
AEG pistol mags usually store about 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs up to about 300 FPS when loaded with 0.12 gram airsoft BBs or around 200 to 250 FPS using 0.20g airsoft BBs. The electric battery powered gearbox system can shoot around 700+ BBs per minute which is estimated if you have enough spare mags to maintain the ammo supply and the battery maintains its charge that long. These pistols can effectively fire airsoft BBs at about 150 foot ranges.
AEG Handgun Quality and Efficiency
AEG handgun quality has grown substantially in the last few years. The earliest gen guns were a bit undependable and sketchy, but the newer designs have the problems resolved and make reliable airsoft secondary weapons. They can be modded with increased magazine capacities and also accommodating larger batteries.
A large advantage of using an AEG handgun is that you have the capability to rewire the wires to use a more robust battery with longer life. Depending on the AEG handgun model, you may be able to get a large output in performance and fire rate by using a two cell Lipo battery (2S Lipo) instead of the standard AEP battery. Take extra precautions when customizing the parts and the gun’s wires because you have to consider the voltages, mAh, and electrical loads of the battery. If you have customization questions, ask an experienced airsoft gun service tech at your local airsoft shop.
Which Airsoft Pistol is Right for Me to Buy?
If you have more than one-hundred dollars to spend on your airsoft handgun, check out a green gas blowback pistol or AEG handgun. If you have between $50 to $100 to shell out, check out a CO2 handgun or more affordable GBB handgun. You can still find a durable airsoft pistol by checking out lower end pistols and by trading with players selling used airsoft pistols if you are trying to save money.
