Airsoft Pistol Product Details

Green Gas HFC 125S Non-Blowback Pistol FPS-345 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.

About Airsoft Pistol Types

Learn more about airsoft sidearms and how you can use them as backup guns or as primary weapons on the airsoft playing field. Practicing your accuracy and getting the best handgun can make a big difference in hitting your shots. Handguns, naturally, are lower range airsoft guns. They are generally crafted after actual handguns or copies of authentic handguns. Many airsoft handguns are fully certified variations of their authentic weapon counterparts. These airsoft guns can function (sans shooting bullets) in the same ways and visually appear similarly to the real guns they are modeled around while blasting airsoft BBs in place of real bullets.

There are a few types of airsoft pistols including CO2, green gas (blowback and non-blowback), spring powered, and AEG automatic electric pistols. Each of these forms of sidearms come with positives and negatives connected with them. Finding out about the varieties of airsoft sidearms lets you decide which type is right for you and your airsoft game play style.

CO2 Airsoft Handgun Details

CO2 airsoft sidearms are one of the most resilient and typical types of handguns. These pistols use pressurized CO2 gas to propel airsoft BBs out of the weapon barrel.

These styles of airsoft pistols are exceptional for airsoft games in cold and snowy weather due to the fact that the compressed CO2 gas is stored in the sealed cylinders and less susceptible to FPS decreases with temperature levels. This gives CO2 airsoft handguns very good FPS and shot consistency while playing airsoft in the winter months for instance where other types of airsoft handguns like green gas cease to function or barely shoot BBs.

About CO2 Gas and CO2 Cylinders

CO2 airsoft pistols are powered by basic 12 gram CO2 cylinders. These cartridges resemble a chrome metal cylinder and contain high-pressure CO2 gas composed of one carbon atom and two oxygen atoms, thus the molecular formula comes out to be “C + O2 “. These atoms are bound in the following alignment “O= C =O”. The gas is kept in the 12 gram cartridge cylinders under very high pressure of close to ~ 800psi which converts to 55bar.

They come sealed to keep the CO2 gas securely within, but soon after they are opened (firing them inside of an airsoft pistol 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 handgun target practice and use up the rest of the excess gas.

CO2 cartridges can be stored for a longtime if the cylinders are stored sealed. They have a supplier’s expiration date usually listed on the package or cartridge, but they will probably survive for a prolonged time past this date if the cartridge seals are not broken.

Green Gas and Propane Airsoft Handgun Details

Green gas airsoft pistols are similar to CO2 pistols, but they do not use CO2 cartridges. The effect on the airsoft battlefield and green gas weapon performance is practically the very same as CO2 handguns with the guns at about 300+ FPS.

The propane gas is kept in the pistol’s airsoft mag that can frequently hold around 15 to 20+ airsoft BBs depending on the handgun model. A series of valves, rubber gaskets, and o-rings keep the gas stored in the mag before the pistol’s trigger is squeezed.

When using a green gas pistol on the airsoft field or arena as a primary or secondary weapon, extra pistol mags are highly recommended for rapidly reloading and engaging the op force. Having additional mags on-hand allows you to re engage in the action in the middle of firefights or while sweeping buildings in CQB (close quarters combat) room-to-room fights.

Green gas handguns are great for CQB at airsoft fields given that long guns and full-sized AEGs are generally not permitted to be used during indoor engagements. This is an essential safety standard due to the close range distance of players during the shooting engagements and the potential for players to be injured. While green gas handguns can still shoot airsoft BBs at about 300 FPS, the shorter pistol barrel assists to keep the joules and energy moving the BB lower compared to AEG airsoft rifles, sniper rifles, and long guns.

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

There are 2 different forms of green gas airsoft handguns. To begin with there are green gas blowback handguns or GBBs. These guns work like a real pistol with the gun’s slide “blowing back” and cycling with every shot. Each time a new airsoft BB is loaded into the chamber, the gas causes the slide to cycle. The result is extremely cool, but the pistols usually cost more and potentially have more parts which can break. The green gas non-blowback airsoft pistols have a fixed slide which does not move. The non-blowback guns generally cost less than GBBs. Performance is around the same when comparing the two types of green gas pistols.

About GBB and Green Gas Issues

Since the green gas or propane is housed in the handgun mag using rubber seals, o-rings, and gaskets, cold temperatures can negatively affect these gaskets and cause the gas to leak out prior to shooting the pistol. The lack of pressure can make the airsoft BBs to only land a couple of feet away (like 10 feet in cold temps ) when it would typically shoot 6mm BBs over 100+ foot distances in warmer weather).

One fix to this issue is to keep the GBB handgun mags warmer by holding them next to your body, beside a heater, or inside your jacket just before game play. If you absolutely desire to play with a reputable airsoft pistol in the cold, it may also be worth getting a CO2 variation of your favorite handgun.

Spring Airsoft Handguns

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

Spring airsoft guns work best in springer battles where airsoft players can only use related, single shot spring handguns or as a transitional weapon for CQB buildings and MOUT sites when you can usually sneak up to other airsoft players to get a guaranteed one-shot-one-kill. In the latter situation, a rapid second follow-up shot isn’t needed since the other player is already hit by the first BB and out of the gameplay or going back to respawn. Look out when attacking several airsoft players given that the springer just fires as fast as you can re-chamber an airsoft BB manually.

About Spring Pistol Effectiveness

Spring handguns are very effective under the best conditions. Their FPS often chronos at about 250 FPS to 300 FPS with lighter 0.12g airsoft BBs. These pistols normally fire the lighter weight airsoft BBs because the springs are less powerful than other types of airsoft weapons. Spring pistols can typically be accurate at up to 120 feet or more with 0.12g BBs but the ability to hit targets accurately diminishes quickly. Choosing standard 0.20g weight airsoft BBs, you will probably have a range of about 60 to 80 feet with increased target accuracy.

AEG Automatic Electric Airsoft Sidearm Facts

AEG airsoft sidearms or AEPs (automatic electric pistols) are also an option to carry as a sidearm on the airsoft field. These automatic electric handguns are commonly powered by mini stick batteries in the weapon’s butt. They work just like an AEG gun and use pressured air forced through electrically cycled pistons, gearboxes, and cylinders to propel airsoft BBs quickly and rapidly.

AEG handgun magazines normally can carry around 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs up to around 300 FPS with 0.12g airsoft BBs or 200 to 250 FPS with 0.20 gram airsoft BBs.

AEG Pistol Quality and Efficiency

AEG pistol quality has increased considerably in the last few years. The initial gen AEP guns were a little bit sketchy and undependable, but the more recent models have the problems resolved and make reliable airsoft secondary guns. They can be modded with increased mag storage capacities and also accommodating more powerful batteries.

A large perk of buying an AEG pistol is that you have the ability to rewire the adapters to use an increased capacity battery. Depending upon the AEG handgun design, you can gain a big boost in functionality by using a two cell Lipo battery (2S Lipo) instead of the standard battery. Take extra precautions when tweaking the parts and the gun’s wires since you must take into account the volts, mAh, and loads of the battery. Ask an experienced weapon tech at your nearest airsoft store or shop if you have customization problems.

Which Airsoft Handgun is Best for Me to Play with?

Choosing the most ideal airsoft sidearm for you depends on your gun budget, how much you plan to play airsoft with it, and where you decide to play. Look at a GBB pistol or automatic electric AEP handgun if you have over one-hundred dollars to invest on your airsoft handgun. These are usually the best of the best, have great efficiency, and can be an excellent investment. If you have in-between $50 to $100 to devote to your airsoft gun purchase, look into a CO2 pistol or a cheaper GBB pistol. Mid-tier guns like these will still function well and will be long lasting sidearms. Look for a low end CO2 or spring pistol if you have less than fifty dollars. You can still get a strong airsoft pistol to use for the handgun airsoft guns.
