Construction and Durability

Plastic Slide and ABS Plastic


The Tokyo Marui Hi-Capa 5.1 features a plastic slide made from high-quality ABS plastic. This material has some advantages, such as:

  • Lightweight: Helps maintain a quicker cycling speed.
  • Cost-effective: Reduces the overall price of the pistol.

However, it might not be as durable as a metal slide, especially when using higher-pressure gas or upgrading the internals.

Metal Parts and Slide

While the slide is plastic, the Hi-Capa 5.1 does include several metal parts throughout the gun, such as:

  • Hammer
  • Trigger
  • Slide lock
  • Outer barrel

These parts contribute to the overall durability and longevity of the pistol. If you’re looking for an even sturdier option, consider upgrading to an aftermarket metal slide. Remember that this may affect performance, like increased gas consumption and slower cycle speed, but it will give your pistol a more realistic and solid feel.

In summary, the construction of the Tokyo Marui Hi-Capa 5.1 offers a good balance between durability and performance for airsoft enthusiasts, with options for further customization and improvements if desired.

Gas System and Efficiency

Green Gas

When using green gas with your Tokyo Marui Hi-Capa 5.1, you’ll experience consistent performance. The pistol’s design takes advantage of the gas flow from its magazine, giving you optimal shots per fill. Ensure your O-rings are properly lubricated to avoid gas leaks and maintain performance quality.

Duster Gas

Duster gas is an excellent alternative for those concerned with their airsoft guns’ power. While Tokyo Marui pistols are often best suited for green gas, duster gas offers a lower-pressure option. This can help to extend the life of your airsoft pistols’ internals, especially in colder weather conditions.

Gas Efficiency

The Tokyo Marui Hi-Capa 5.1 boasts impressive gas efficiency. Here are some key factors to consider:

  • Shots per fill: You can expect 50-60 shots per fill in normal temperature conditions when using green gas.
  • Magazine capacity: With a 31-round magazine, you can enjoy extended gameplay without frequently refilling your gas.
  • Temperature effects: Remember that gas efficiency is affected by temperature. Warmer temperatures usually give you better performance, while colder temperatures may require more frequent fills.

Overall, your Tokyo Marui Hi-Capa 5.1’s gas system and efficiency are designed to give you a satisfying airsoft experience, providing proper care and maintenance. Choose the right gas type for your specific needs, and ensure your O-rings are well-maintained to enjoy this airsoft pistol’s potential fully.

Barrel Components and Upgrades

Inner and Outer Barrel

The Tokyo Marui Hi-Capa 5.1 has a high-quality inner barrel with excellent accuracy. However, you might consider upgrading to a tight-bore barrel for improved performance. Some popular brands for tight-bore inner barrels include Prometheus, PDI, and Maple Leaf.

The outer barrel is lightweight plastic but can be replaced with sturdier metal aftermarket options. This not only enhances the look but also adds to the durability of your Hi-Capa.

Threaded Barrel

You’ll need a threaded barrel if you want to attach a suppressor or tracer unit. Upgrading to a metal threaded outer barrel will allow you to attach accessories and contribute to increased stability during firing.

Aftermarket Parts

A wide range of aftermarket parts is available for the Tokyo Marui Hi-Capa 5.1. Some popular upgrades to enhance performance include:

  • Hop-up units: Modify or upgrade your hop-up for better accuracy and consistency.
  • Nozzles: High-quality nozzles offer improved gas efficiency and reliability.
  • Recoil springs: Upgraded recoil springs allow smoother cycling and snappier blowback action.

When upgrading your Tokyo Marui Hi-Capa 5.1, always consider the compatibility and quality of the parts. Investing in trusted brands and seeking advice from experienced players will help you make the best choices for your airsoft sidearm.

Magazine and BBs

Capacity and Compatibility

The Tokyo Marui Hi-Capa 5.1 comes with a 31-round gas magazine. You’ll appreciate the extra capacity during intense airsoft skirmishes. The magazines are also compatible with other Hi-Capa models, allowing easy interchangeability.

BB Sizes

When it comes to BBs, the recommended size for the Hi-Capa 5.1 is 6mm. Using the proper BB size ensures optimal performance and prevents damage to your airsoft gun. Stick with high-quality BBs to get the best accuracy and avoid jams.

Always use the right BB size and quality for your Hi-Capa 5.1 to maximize your airsoft experience.

Safety Features and Controls

Ambidextrous Thumb Safety and Grip Safeties

Tokyo Marui Hi-Capa 5.1 features an ambidextrous thumb safety allowing both right and left-handed users to operate it with ease. To engage the safety, simply push it up on either side. Coupled with a grip safety, these mechanisms ensure that the airsoft gun won’t accidentally discharge when not intended.


The hammer in your Tokyo Marui Hi-Capa 5.1 is of solid construction and design, providing reliable performance. When the slide is racked, the hammer pulls back and gets ready to fire; once the trigger is pulled, it releases the hammer, which ignites the propellant and propels the BB.


Tokyo Marui implemented a double-action/single-action trigger system. Pulling the trigger for the first time is in double action, requiring a little more pressure. After the first shot, the slide will rack, setting the hammer back and enabling single-action mode – this provides a lighter, smoother trigger pull for quick follow-up shots.

Slide Stop

The slide stop is a small, textured lever mounted on the left side of the frame. It holds the slide open after the last round is fired, signaling the need to reload. To release the slide stop, you can push down on the lever or pull back the slide, ensuring a smooth and quick transition back into action.

  • Ambidextrous Thumb Safety: Accessible for both right and left-handed users
  • Grip Safeties: Prevents accidental discharges
  • Hammer: Solid construction and reliable performance
  • Trigger: Double-action/single-action mechanism for varied trigger pulls
  • Slide Stop: Indicates when reloading is required and allows for a smooth transition

Comparisons and Alternatives

You may notice several differences when comparing the Tokyo Marui Hi-Capa 5.1 to the Glock 17. The Glock 17 provides a more realistic design resembling its real-steel counterpart. However, the Hi-Capa 5.1 outperforms the Glock 17 in terms of gas efficiency and magazine capacity.
