There is no single best GS45 build for every mode. CODMunity’s published configurations offer separate starting points for Multiplayer, high-round Zombies, and close-range Warzone—but their listed updates are from 2025, so treat them as recommendations to check in the live Gunsmith, not confirmed October 2026 meta builds.
What the GS45 is—and what “best” means
Activision describes the GS45 as a semi-automatic pistol firing .45 Auto rounds, with close-range stopping power. Its launch weapon guide lists it as unlocking at Player Level 28. Activision’s weapon guide also explains that Gunsmith builds can be used across Multiplayer, Round Based Zombies, and Warzone.

The strongest configuration depends on the mode and how you use the pistol. Activision identifies Firepower, Accuracy, Handling, and Mobility as weapon attributes, alongside details such as recoil, reload quickness, and bullet velocity. Compare those values in Gunsmith rather than assuming an attachment is an upgrade in every build. Activision’s Season 04 patch notes also say attachment balance is not intended to make every attachment viable on every weapon; attachments should serve different builds and playstyles. Read the Season 04 patch notes.
Recommended GS45 builds by mode
The attachment combinations below are those published by CODMunity. They are useful starting points, not independently tested results or a guarantee of current balance.
#1 Best Overall
- Cross Gen-Bundle of Call of Duty: Black Ops 6 includes Xbox Series X and Xbox One versions of the game.

Multiplayer: versatile sidearm
- Optic: Kepler Microflex
- Muzzle: Suppressor
- Barrel: Long Barrel
- Magazine: Extended Mag II
- Rear Grip: Ergonomic Grip
CODMunity labels this its “Best GS45 Versatile Loadout (BO6)” and lists an update date of July 8, 2025. Its page describes the pistol as an underpowered sidearm with rocky recoil and blocky sights. This setup pairs an optic with range, magazine, and handling choices; that description of its priorities is an interpretation of the parts, not a tested performance claim. See CODMunity’s GS45 builds.
Zombies: high-round setup
- Muzzle: Suppressor
- Magazine: Extended Mag II
- Stock: Akimbo GS45
- Laser: Steady Aim Laser
- Fire Mods: Rapid Fire
CODMunity lists this configuration for high rounds and advises getting PHD Flopper early, saying the GS45 gains explosive damage when Pack-a-Punched. That is the guide’s advice, not an official Activision recommendation; its displayed update date is August 5, 2025. Akimbo favors hipfire and dual-wield play, but it comes with a substantial range trade-off (see the attachment details below).
Rank #2
- Developed by Treyarch and Raven, Call of Duty: Black Ops 6 is a spy action thriller set in the early 90s, a period of transition and upheaval in global politics, characterized by the end of the Cold War and the rise of the United States as a single superpower.

- The Black Ops 6 Campaign provides dynamic moment-to-moment gameplay that includes a variety of play spaces with blockbuster set pieces and action-packed moments, high-stakes heists, and cloak-and-dagger spy activity.
- In a best-in-class Multiplayer experience, players will test their skills across 16 new maps at launch, including 12 core 6v6 maps and 4 Strike maps that can be played 2v2 or 6v6.
- Black Ops 6 also marks the epic return of Round-Based Zombies, the fan-favorite mode where players will take down hordes of the undead in two brand-new maps at launch. Post-launch, players can look forward to even more exciting maps and groundbreaking experiences dropping into both Multiplayer and Zombies.
Warzone: close-range build
- Muzzle: Ported Compensator
- Barrel: Reinforced Barrel
- Magazine: Extended Mag II
- Rear Grip: Ergonomic Grip
- Fire Mods: Recoil Springs
CODMunity lists this as a close-range configuration. Its page reports average time-to-kill figures of 1,049 ms at 0–10 m and 1,081 ms at 10–40 m for this build. These are the guide’s displayed model/stat figures, not independently tested results or a guarantee in a match; the displayed update date is December 4, 2025.

CODMunity’s attachment table lists Akimbo GS45 as a Stock unlocked at Level 31, with increased hipfire values and a 25.8% range reduction. It is therefore a playstyle choice for close hipfire use, not a universal upgrade. The table lists Extended Mag II at Level 22 and reports a 14-round magazine increase. Verify unlocks and values in your current Gunsmith, since in-game figures may change with updates. CODMunity’s attachment table and build listings.

How to choose and verify your build
- Choose the mode and intended use first: versatile Multiplayer sidearm, high-round Zombies hipfire/dual-wield, or close-range Warzone.
- Open the GS45 in Gunsmith and equip the corresponding listed attachments that you have unlocked.
- Compare the weapon attributes and detailed values—especially recoil, handling, reload quickness, and bullet velocity—against what matters for your playstyle.
- Check the in-game attachment values after balance updates. The CODMunity builds surfaced with 2025 dates, which does not establish them as the current October 2026 meta.
