"Lock On! Kachidoki Charge!"

- Standard finisher announcement for Gun Mode

"Lock On! 1, 10, 100, 1,000, 10,000, 100,000,000, 1,000,000,000,000, Muryodaisu! Kachidoki Charge!"

- Standard finisher announcement for Taiken Mode

"Soiya! Kiwami Au Lait!"

- Taiken Mode's finisher announcement via Sengoku Driver

The Hinawa Daidai DJ Ju (火縄大橙DJ銃) is Kamen Rider Gaim's weapon while in Kachidoki Arms, which resembles an updated and futuristic Tanegashima rifle. This weapon is accessed through the Kachidoki Lockseed. However, it can be summoned and utilized by Gaim if he assumes Kiwami Arms.

By scratching the disk-like DJ Table (DJテーブル) apparatus, Gaim can enhance his shots, which are further subjected by the settings of the DJ Pitch (DJピッチ) switch, which is set at Medium by default, but can be set at either Low or High. To further enhance the shots, Gaim has to scratch the DJ Table once again, then pull the trigger to show the effect.
 * Low: Cannon-like bursts
 * Medium: Shotgun-like blasts
 * High: Machine gun-like firing speeds

Combinations
The DJ Gun can combine with the Musou Saber for the stronger Taiken Mode (大剣モード), making the Great Orange Blade (大橙刃 (ダイダイジン)) edge piece appear on the back of what would be the Matchlock Grip (火縄グリップ).

Finishing attacks
By inserting the Kachidoki Lockseed into the DJ Gun's Drive Bay (ドライブベイ) and locking it in place, Gaim can perform a Kachidoki Charge (カチドキチャージ) finishing attack.
 * Unnamed Rider Shooting: In Gun Mode, Gaim fires a large ball of energy from the DJ Gun at the enemy.
 * Hinawa Daidai Musou Zan (火縄大橙無双斬): In Taiken Mode, Gaim ignites the DJ Gun in flames before unleashing a powerful slash on the enemy. In Kiwami Arms, Gaim performs this attack using the Sengoku Driver's Au Lait function.
