Information About the Designs of Airsoft Handguns
Learn more 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 handgun can make a big difference in nailing your shots. Handguns, naturally, are much shorter range airsoft weapons. They are commonly fashioned after firearm sidearms or models of authentic handguns. A large number of airsoft sidearms are fully licensed models of their actual handgun counterparts. These airsoft guns can run in the same ways and look and feel similarly to the real guns they are designed after while blasting airsoft BBs in place of real-world bullets.
There are a few varieties of airsoft handguns such as CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric gun pistols. Each of these styles of pistols has negatives and positives associated with them. Learning about the types of airsoft handguns lets you decide which type is right for you and your airsoft gameplay style.
Details About CO2 Airsoft Sidearms
CO2 airsoft handguns are one of the most common and heavy duty types of sidearms. These handguns use sealed CO2 gas cylinders to force airsoft BBs out of the weapon barrel.
These styles of airsoft handguns are great choices for airsoft games in colder weather conditions considering that the high pressure CO2 gas is stored in the sealed cylinders and less vulnerable to FPS decreases with low temperature. This fact gives CO2 airsoft pistols good FPS and shot consistency while playing airsoft in the wintertime for example where other sorts of airsoft sidearms like green gas cease to operate or hardly fire BBs.
About CO2 Gas and CO2 Cylinders
CO2 airsoft pistols are powered by conventional 12 gram CO2 cartridge cylinders. These cartridges look similar to a shiny metallic cylinder and hold high pressure CO2 gas made up of 1 carbon atom and a couple of oxygen atoms thus the molecular formula of “C + O2”.
The CO2 gas cylinders cannot be refilled and you can typically order them in bundles of 12, 20, 50, or 100 12 gram CO2 cartridges. They come sealed to retain the CO2 gas safely and securely within, once they are opened (firing them inside of an airsoft gun breaks the seal) cartridges will start to lose pressure if they are left unused. You need to attempt to consume the whole CO2 cartridge the very same day you open the seal. If the airsoft games end and you still have CO2 gas left, use the chance to do some pistol target practice and expend the remainder of the extra gas. There is no gas level indication on the cartridge so you need to shoot up until the gun stops firing.
If they are kept sealed, CO2 cartridges can be stored for a while. They have a supplier’s expiry date normally listed on the box or cartridge, but they will maintain pressure for an extended time past this date if the cartridge seals are not tampered with.
Green Gas and Propane Airsoft Pistol Info
Green gas airsoft pistols are similar to CO2 handguns, however they do not use CO2 cartridges. As an alternative, they use green gas or propane gas for propellant to fire the airsoft pellets. The effect on the battlefield and green gas handgun operation is almost the same as CO2 pistols with the guns shooting up to 300+ feet per second. Shots are efficiently fired in fully-automatic or semi-automatic shooting modes and precisely hit targets at very short to mid-range distances.
The green gas is kept in the pistol’s mag that can commonly hold in-between 15 to 20+ airsoft BBs based on the pistol style. A series of valves, rubberized gaskets, and silicone o-rings keep the gas stored in the magazine until the handgun’s trigger is pulled.
When playing with a green gas handgun on the airsoft field or arena as a main or backup weapon, extra handgun mags are highly recommended for rapidly reloading and getting back into the game. Having extra magazines on-hand allows you to reengage in the action during firefights or while clearing buildings in CQB (close quarters combat) room-to-room fights.
Green gas handguns are suitable for CQB at airsoft fields given that rifles, long guns, and full-sized AEGs are usually not authorized to be used for indoor shooting. This is a safety regulation due to the close range proximity of airsoft players during the shooting engagements and the potential for players to be injured. While green gas pistols can still shoot airsoft BBs at about 300 FPS, the short pistol barrel aids to keep the joules and energy pushing the BB lower compared to airsoft rifles, sniper rifles, and long guns.
Thinking About Green Gas Blowback (GBB) VS Green Gas Non-blowback
There are 2 various forms of green gas airsoft handguns. First there are green gas blowback pistols or GBBs. These pistols operate like a legitimate handgun with the gun’s slide “blowing back” and moving with every shot. The propane gas induces the slide to cycle every time a new airsoft BB is chambered. The result is extremely cool, however the guns often cost more and likely have more parts that can break. The green gas non-blowback airsoft guns have a fixed slide which does not move. The non-blowback handguns commonly cost less than GBBs. Efficiency is about the same between the two styles of green gas handguns.
About GBB and Green Gas Issues
Due to the fact that the green gas or propane gas is held in the mag by using rubber seals and silicone gaskets, cold temps can influence these gaskets and cause the gas to leak out before shooting the pistol. The lack of pressure can cause the airsoft BBs to merely shoot a few feet away (like 10 feet in cold temps ) when the green gas pistol would normally shoot BBs over 100+ foot distances in warmer temps).
One fix for this problem is to keep the GBB pistol mags warmer by putting them next to your body prior to airsoft game play. This can help to warm up the seals and help to seal in the green gas. If you honestly prefer to play with a trustworthy airsoft handgun in the cold, it may also be worth checking out a CO2 variation of your favorite pistol. The CO2 cartridges come sealed and the gun shoots far better in sub-freezing temperatures and while playing in the snow.
Facts About Spring Airsoft Pistols
Spring airsoft sidearms are powered by strong springs that propel the BBs down the gun barrel. They are normally able to only shoot one BB. The manual actions of firing, reloading, and cocking spring airsoft guns makes the weapon’s fire rate much slower than CO2, green gas, and GBB handguns. When fighting foes on the airsoft field with upgraded weapons, automatic airsoft AEG SMGs, rifles, and CO2, green gas, or GBB airsoft handguns, this makes spring airsoft pistols fun to use, but less efficient.
Spring guns work most effectively in springer battles where airsoft players can exclusively use similar, single shot spring weapons or as an alternative backup weapon for CQB settings when you can frequently quietly sneak up on other airsoft game players to get a guaranteed one-shot-one-kill. In the latter case, a rapid 2nd follow-up shot is not really needed because the other player is already hit and out of the game or heading back to respawn. When engaging a number of players considering that the weapon just shoots as quickly as you can re-chamber an airsoft BB by hand, be cautious.
About Spring Handgun Effectiveness
Spring handguns are considerably effective under the best conditions during airsoft games. Their FPS commonly chronos at about 250 FPS to 300 FPS with lighter 0.12g airsoft BBs. These weapons normally fire the lighter weight airsoft BBs due to the fact that the springs are less powerful than other types of airsoft guns like rifles. Spring handguns can normally be accurate at up to 120 feet or more with 0.12g BBs but the ability to hit targets is reduced rapidly. Shooting normal 0.20 gram weight airsoft BBs, you will very likely have a reduced shooting distance of about 60 to 80 feet with increased precision.
AEG Automatic Electric Airsoft Pistols
AEG airsoft sidearms or AEPs (automatic electric pistols) are definitely a viable option to bring as a backup weapon on the airsoft field. These automatic electric handguns are often powered by mini stick batteries in the weapon’s grip. They work much like an AEG SMG and use forced air pumped through electrically cycled pistons and cylinders to propel airsoft BBs quickly and very quickly at that.
AEG pistol mags generally store around 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs right up to around 300 FPS using 0.12g airsoft BBs or around 200 to 250 FPS using 0.20g airsoft BBs. The electric gearbox system can shoot around 700+ BBs per minute which depends if you have enough spare mags to reload (after every 20 to 30 shots) and the battery holds out that long. These pistols can accurately shoot airsoft BBs at around 150 foot ranges.
AEG Handgun Quality and Efficiency
AEG handgun quality has actually grown substantially over the last few years. The initial gen guns were a bit sketchy and unreliable, however the newer models have the problems worked out and make effective airsoft secondary guns. They can be modded with increased mag capacities together with accommodating larger batteries.
A huge perk of carrying an AEG handgun is that you have the capacity to rewire the battery wires to use an enhanced battery. Depending upon the AEG handgun type, you can gain a sizable jump in efficiency utilizing a 2 cell Lipo battery (2S Lipo) in place of the standard AEP battery. Take extra precautions when tweaking the parts and the gun’s wires since you must consider the voltages, mAh, and loads of the battery. Ask a qualified airsoft tech at your nearest airsoft shop if you have modding concerns.
Which Airsoft Sidearm is Best for Me to Buy?
Selecting the most ideal airsoft handgun for you depends upon how much you can afford, how often you plan to play airsoft using it, and where you hope to play. Look into a green gas blowback handgun or AEG pistol if you have more than $100 to spend on your airsoft pistol. These guns are normally the top of the line, have good performance, and can be a really good handgun to purchase. Check out a CO2 pistol or less costly GBB handgun if you have about $50 to $100 to spend. Middle of the road guns like these will still get the job done and are pretty durable sidearms. If you have $50 or less, look for a cheaper CO2 or spring pistol. You can still get a long-lasting airsoft handgun to use for the handgun airsoft guns.
