Green Gas KWA M9 300 FPS Blowback Airsoft Gun

Airsoft Pistol Product Features

Airsoft Pistol Type Info

Find information about airsoft pistols and sidearms and how you can use them as backup weapons or as primary weapons on the airsoft playing field. Numerous airsoft pistols are completely certified releases of their authentic pistol counterparts and operate and appear in the exact same ways while shooting airsoft BBs instead of actual bullets.

There are a variety of airsoft pistols including CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric sidearms. Each of these kinds of handguns has negatives and positives connected with them. Learning about the varieties of airsoft pistols helps you choose which type is right for you and your airsoft gameplay style.

About CO2 Airsoft Sidearms

CO2 airsoft handguns are one of the most durable and popular types of pistols. These pistols use CO2 stored in small cylinders to push airsoft BBs out of the gun barrel.

These kinds of airsoft guns are good for playing airsoft in cooler temperatures given that the pressurized CO2 gas is stored in the sealed cylinders and less susceptible to FPS decreases caused by temperature levels. This fact gives CO2 airsoft pistols exceptional FPS and shot consistency while playing airsoft in the winter season for instance where other sorts of airsoft sidearms like green gas stop performing or barely fire BBs.

Additional Info About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft pistols are powered by common 12 gram CO2 cartridge cylinders. These cartridges look similar to a metal cylinder and hold high-pressure CO2 gas consisting of one carbon atom and a pair of oxygen atoms thus the molecular formula is “C + O2”.

They come sealed to keep the CO2 gas securely inside, however when they are opened (shooting them in an airsoft weapon breaks the 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 handgun target practice and use up the rest of the excess gas.

CO2 cartridges can be stored for a while if the cylinders are kept sealed. They are made with a maker’s expiry date normally printed on the package or cartridge, however, they will probably last for a very long time past this date if the cartridge seals are not punctured.

Green Gas Airsoft Sidearm Details

Green gas airsoft handguns resemble CO2 pistols, however they do not use CO2 cartridges. Alternatively, they use green gas or propane gas for propellant to propel 6mm airsoft pellets. The result on airsoft games and green gas pistol operation is basically the same as CO2 pistols with the weapons shooting up to about 300+ feet per second (FPS). Shots are efficiently fired in automatic or semi-automatic shooting modes and accurate at short to mid-range ranges.

The green gas is kept in the pistol’s mag and can often hold in-between 15 to 20+ BBs depending on the handgun style. A set of valves, rubber gaskets, and o-rings keep the propane sealed in the mag prior to when the pistol’s trigger is squeezed. It is a good plan to top off and fill up your green gas in the mag each time you load it into the handgun. Pistol-wielding airsoft players can even bring extra bottles of green gas or propane in the field for reloading magazines between breaks in the battle or in-between missions.

When running a green gas pistol on the airsoft field or arena as a main or backup gun, extra magazines are strongly recommended for quickly reloading and engaging opponents. Having extra mags on-hand allows you to reengage in the action during firefights or while sweeping buildings in CQB (close quarters combat) room-to-room fighting.

Green gas pistols are suitable for CQB at airsoft fields considering that rifles, long guns, and full-sized AEGs are typically not authorized to be used during indoor game play. This is an essential safety rule because of the close quarters distance of players during shooting engagements. While green gas pistols can still shoot airsoft BBs at around 300 FPS, the shorter handgun barrel helps to keep the joules and energy moving the BB lower compared to AEGs, sniper rifles, and long guns.

Thinking 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 pistols or GBBs. These guns run like a genuine handgun with the pistol slide “blowing back” and cycling with every shot. The propane causes the slide to cycle every time a new airsoft BB is chambered. This functioning while shooting is extremely cool, however the GBB handguns typically are more expensive and possibly have more which can break. The green gas non-blowback airsoft pistols have a stationary slide which does not cycle. The non-blowback guns generally cost less than GBBs. Performance is around the same between the two styles of green gas pistols.

About GBB and Green Gas Limitations

Because the green gas or propane is stored in the mag by rubber seals and gaskets, cold weather can negatively affect these o-rings and cause the stored gas to leak out before shooting. The lack of pressure can cause the airsoft BBs to only land a number of feet away (like 10 feet in the cold ) when the gun would normally shoot 6mm BBs over 100+ foot distances in warmer weather conditions).

One fix to this problem is to keep the GBB pistol magazines warmer by holding them next to your body or near a heat source before game play starts. If you absolutely want to play with a trustworthy airsoft handgun in the cold, it may additionally be worth getting a CO2 version of your preferred pistol.

Spring Airsoft Sidearms

Spring airsoft handguns are powered by powerful springs that fire the airsoft BBs out of the gun barrel. They are normally single shot. The manual functioning of reloading, shooting, and cocking spring handguns makes the fire rate much slower than CO2 and GBB pistols. When dealing with other players on the airsoft field with fully automatic airsoft AEG assault rifles, SMGs, sniper rifles, and CO2 or GBB airsoft pistols, this can make them enjoyable to use, however less effective.

Spring sidearms perform the best in springer battles where game players can just use related, single shot spring guns or as an alternative backup gun for CQB environments when you can frequently sneak up to other airsoft opponents to get an assured one-shot-one-kill. In the latter case, a quick 2nd follow-up shot isn’t required considering that the other opponent is now hit and out of the game play or moving back to respawn. When engaging a number of foes considering that the springer simply fires as quickly as you can re-chamber an airsoft BB by hand, be careful.

About Spring Handgun Performance

Spring handguns are remarkably useful under the proper scenarios and airsoft games. Their FPS generally chronos at about 250 FPS to 300 FPS with 0.12g airsoft BBs. These handguns normally fire the lighter weight airsoft BBs since the coiled springs are less effective than other kinds of airsoft weapons. Spring handguns can normally engage targets at ranges of up to 120 feet or more with 0.12g BBs but the ability to hit targets decreases rapidly. Using standard 0.20g weight airsoft BBs, you will probably have a reduced range of around 60 to 80 feet with increased target accuracy.

AEG Automatic Electric Airsoft Pistols

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

AEG pistol magazines typically can carry around 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs right up to around 300 FPS with 0.12g airsoft BBs or 200 to 250 FPS using 0.20g airsoft BBs. The electrical gearbox system can shoot around 700+ BBs per minute which depends on if you have enough spare mags to reload the gun and the battery holds out that long. These pistols can precisely fire airsoft BBs at around 150 foot distances.

AEG Pistol Quality and Efficiency

AEG handgun quality has grown significantly in recent years. The early gens were a bit questionable and unreliable, but the new models have the issues worked out and make reliable airsoft backup weapons. They can be improved with enhanced magazine storage capacities along with accommodating bigger batteries.

A substantial benefit of using an AEG pistol is that you have the ability to rewire the battery connectors to use a larger capacity battery. Depending on the AEG handgun type, you can get a sizable jump in efficiency by using a two cell Lipo battery (like an 2S Lipo) as an alternative for the stock mini battery.

What Airsoft Handgun is Best for Me to Play with?

If you have over $100 to spend on your airsoft pistol, take a look at a green gas blowback handgun or AEG pistol. If you have around $50 to $100 to upgrade your gun, review a good quality CO2 handgun or more affordable GBB pistol. If you are on a budget, you can still get a durable airsoft handgun to use for the handgun games.
