Tips for Maximum Accuracy

Choose the Right Pellets

Accuracy depends heavily on pellet selection. For .177 caliber, try H&N Field Target Trophy or JSB Exact pellets. For .22, Crosman Premier Hollow Points or JSB Jumbo work well. Test multiple brands to find what your pistol likes best. See our complete buying guide for more tips.

Maintain Consistent CO2 Temperature

CO2 pressure varies with temperature. Let your pistol warm up to ambient temperature before shooting for best consistency. Avoid rapid fire, which cools the cartridge and drops velocity.

Practice Proper Grip

A consistent grip is essential for accuracy. Hold the pistol firmly but don’t squeeze so hard you shake. The same grip every shot ensures consistent point of impact.

Consider a Rest or Support

For testing accuracy, use a pistol rest or sandbags. This removes human error from the equation and shows you the pistol’s true potential.

Upgrade When Ready

Pistols like the Crosman 2240 have huge aftermarket support. Longer barrels, better triggers, and adjustable sights can transform an accurate pistol into a tack-driver.

Frequently Asked Questions

What is the most accurate CO2 pistol?

For pure accuracy, the Crosman 1701P Silhouette with its Lothar Walther match barrel is hard to beat. However, the Crosman 2240 offers exceptional accuracy at a fraction of the price and remains the enthusiast favorite.

Are pellet pistols more accurate than BB pistols?

Yes. Pellet pistols with rifled barrels spin the projectile for stability, similar to a firearm. BB pistols typically have smoothbore barrels, which limits accuracy. For precision shooting, always choose pellets.

How many shots per CO2 cartridge?

Most .177 CO2 pistols get 50-80 shots per cartridge. .22 caliber pistols typically get 40-60 shots. Blowback models use more CO2 and deliver fewer shots.

Can CO2 pistols be used for pest control?

Yes, especially .22 caliber models like the Crosman 2240. They’re effective for mice, rats, and small birds at close range. Always ensure humane shot placement and check local regulations.

What’s better for accuracy: .177 or .22?

.177 pellets are typically more accurate due to their higher velocity and flatter trajectory. However, .22 caliber delivers more energy and is better for pest control. For pure target shooting, .177 is preferred.

Final Verdict

For most shooters seeking accuracy, the Crosman 2240 offers the best combination of precision, value, and upgrade potential. It’s the “1911 of air pistols”—a proven platform that rewards good technique and invites customization.

If you’re serious about competition or want the absolute best accuracy, the Crosman 1701P Silhouette delivers match-grade performance. For those wanting realistic training, the Sig Sauer P226 ASP provides surprising accuracy in a semi-auto package.

Whatever you choose, remember that the shooter matters more than the equipment. Practice fundamentals, experiment with pellets, and enjoy the journey to tighter groups!
