FAQ

Does the Gentleman's Sidepiece come with a magazine?

No, a magazine is not included with this build. You will need to purchase a compatible Tokyo Marui Hi-Capa magazine separately. Standard Hi-Capa 5.1 magazines are widely available and work great with this platform.

Is this build ready to use right out of the box?

Yes - the Gentleman's Sidepiece is a fully assembled and professionally tuned custom build. All components are installed and dialed in by Tapp Airsoft, so you simply add a magazine and BBs and you're ready to play. No additional gunsmithing or tuning is required.

What does "pistol primary" mean, and is this build suited for it?

Running pistol primary means using a pistol as your main weapon rather than as a backup sidearm. It demands a highly reliable, high-performing handgun that can keep up with rifle-wielding opponents. The Gentleman's Sidepiece is specifically built and marketed for aggressive pistol primary play, with upgraded internals chosen to maximize consistency, range, and cycle speed.

What is Cerakote and why does it matter?

Cerakote is a polymer-ceramic coating applied to firearms and airsoft replicas to provide superior durability, corrosion resistance, and scratch protection compared to standard paint or anodizing. The in-house application by Tapp Airsoft ensures a high-quality, consistent finish that holds up through heavy field use while giving the pistol a premium, custom appearance.

Can I upgrade or modify this build further?

Absolutely. Because the Gentleman's Sidepiece is built on the Tokyo Marui Hi-Capa 5.1 platform, it benefits from one of the largest aftermarket ecosystems in airsoft. Nearly every part is replaceable or upgradeable, and Tapp Airsoft also offers support and additional custom work if you want to take the build even further.
