5 Best CO2 Airsoft Pistols For 2018

Being equipped with the best CO2 airsoft pistol can give you the advantage you've been looking for, especially when in short-range, close combat. Having the tools you need to succeed on the course or field starts with the tools you equip yourself with.

That also doesn't just mean going out and purchasing any airsoft pistol on the market—it means getting the best CO2 airsoft pistol that fits your preference, budget, and playing style.

Pistols are compact and easy to use, the learning curve behind the way they work is very short and simple. That way, investing in an airsoft pistol makes it an easy choice for beginners. Even if you aren't used to carrying around a small weapon, you'll get easily acclimated to the feel and function of it. They are also designed to have a realistic look and feel, which can make you feel that much more of a serious player. The best CO2 airsoft pistol will come with the authenticity of appearance in most brands’ products you're considering.

Co2 vs Green Gas Airsoft Pistols - Benefits Of CO2

When comparing different types of airsoft pistols, you can have your pickings of a couple of different variants—from green gas/propane to red gas/CO2.

Co2 vs Green Gas Airsoft Pistols

Green Gas/Propane 

This gas is essentially propane mixed with a silicone oil, scented with another chemical to make it bearable for players to use and not cough out their lungs. Most guns on the market are fueled with green gas.

Red Gas/CO2  

Using the same power as paintball guns, airsoft can also be powered by CO2. However, unlike those large tanks that you usually see attached to paintball guns, they come enclosed in the airsoft pistol, decreased in size and compressed into 12g capsules. Compared to other gases normally used in airsoft, you'll have more pressure.

Benefits of CO2

Not only does CO2 add high-pressure to your gun, it also has a disposable cylinder and uses a power outlet—which makes it easy to refill. Upon purchasing, it comes pre-filled already with 12 grams of liquid carbon dioxide and if you're willing to make an investment, can come with refillable reservoirs. Normally, these spaces are seen with paintball guns but are reserved for the finest CO2 guns, too.

When making the comparison to pre-charged pneumatic guns, CO2 airsoft pistols don't require a pressure regulator—since the airsoft guns run on low-to-moderate power. When converting the liquid CO2 to its usable form, it also doesn't need a very big tank—using just the right temperature to form.

Co2 Airsoft Pistols and Velocity

If you're looking for speed, CO2 airsoft pistols can get you the velocity you need. With a muzzle velocity of 400 fps—even up to 600 fps—even though most fields only allow 400 FPS. If you have a faster gun, it might be worth your while to play on an outdoor field, which usually has less strict regulations.

CO2 airsoft pistols also will give you more consistent projectile speeds across the board. Using pressurized steel 12-gram cartridges of carbon dioxide gas, the speed of the shot is unaffected by extreme temperatures.

Blowback vs Non-Blowback Co2 Airsoft Pistols

Another decision you have to make when purchasing a CO2 airsoft pistol is if you want your gun to perform with non-blowback or blowback.

Here are also a few features explaining the two:

Blowback Pistol 

The blowback pistols use compressed gas to fuel their power, insinuating the trigger response, adding the recoil, and causing the slide to shoot back—just like a real pistol. Blowback guns utilize much more gas to propel the BB and reload the gun. However, they are much more realistic than the non-blowback variation.

Non-Blowback Pistol

Non-blowback gives more consistent air to the shot because it doesn't have to use some of that air for blowback purposes.

Non-blowback guns also don't have as complicated of a system and fewer moving parts than the blowback, which means less maintenance, an easier cleaning process and less chance of breaking something.

Across the board, these types of pistols are much more affordable and are generally used by beginners because of the economic save of gas and price range. They also require less build up to the shot, leaving you responsible for just pulling the trigger.

Why You Need An Airsoft Sidearm

Sidearm Pistol Benefits

When you're playing airsoft and you're in close quarters, using an airsoft pistol can get you as close as possible to cover because you'll have a smaller target but you should aim to use the CO2 pistols because they have more consistent shots.

Especially if you're planning to play somewhere where the temperature is extremely hot or cold, the best CO2 airsoft pistols are less affected by it—if anything, they're not affected at all. The best part about it? You can also buy the 12 g cartridges that you need of CO2 in bulk, saving your time and money.

However, being able to use an airsoft sidearm and maneuver easily throughout the game and course (especially if it’s a small one indoors), will put you at a major advantage. You can not only inconspicuously maneuver throughout, your small gun also creates a smaller target for other players to be able to get to you.

How Much Does Co2 Airsoft Pistol Usually Weigh 

Although the weight of a gun is definitely an important factor to carrying it around with you throughout the game, you have to realize that what’s advantageous about these pistols is that they generally weigh much, much less than the other airsoft guns—and they're much smaller, too!

Even though you cannot pinpoint a specific weight as an average for these types of guns, you can expect that they can come in weighing anywhere between under a pound and four pounds. However, this might also vary because the pistols come in a variety of different sizes.

What else affects the weight? The material that the pistol is made out of affects the weight. For example, if you take two pistols of equivalent size but one made out of different materials—like full metal or plastic, you'll get two different sizes.

Full Metal vs Plastic Pistol 

If you want to save money but still get the power of a blowback pistol, you can opt for a plastic one or one that has very few external metal parts. Unfortunately, you get what you pay for—the plastic guns really feel like a toy rather than feeling realistic. Therefore, if you really want to get that authentic gun feel and power, you need to feel comfortable with dishing out the extra money. 

The CO2 blowback guns come in different material and different types of designs—to get as realistic, as possible. The full metal ones, however, are much heavier in weight and most players like to think they shoot better.

Maintaining You Co2 Airsoft Pistol 

Whether you are a beginner or an experienced player, one of the most important things you ought to know is how to maintain or care for your airsoft pistol. Especially if you have one that runs on CO2, you should know the ins and outs of treating it. If maiyou're just putting in that CO2 gas straight from your 12 g cartridge, you're basically just feeding your gun untreated gas. This will ultimately take years off of your gun’s lifespan and the quality of its usage will go down! You can easily clean and maintain your pistol, before and after every usage.

This is done by easily applying a bit of silicon oil to all the moving parts of the gun (they are normally pretty easy to disassemble). You also should apply lubricant to the seal of the gun where the CO2 goes in or else there is a possibility that it might start leaking.

Final Words 

If you're looking for the perfect CO2 airsoft pistol, this guide should give you an idea of what to look out for and which ones are going to be a good fit for you. Take into account your budget, your playing style, and the scenario or course you're going to be playing on—all these factors will affect which type of gun you need.
