If you're running Glock 9mm, .40 S&W, or .357 Sig models and want faster, more decisive magazine changes, the Rival Arms Aluminum Anodized Black Mag Baseplate is built for exactly that. This aftermarket baseplate replaces your stock Glock magazine base with a precision-machined aluminum unit that adds weight to the magazine itself—a seemingly small change that makes a tangible difference in how quickly a spent mag drops free during reloads, especially under pressure or time constraints at the range.
Rival Arms manufactures this baseplate using CNC milling, a process that holds tighter tolerances and delivers more consistent geometry than stamped alternatives. That precision translates to reliable fit and function across multiple shooting sessions. Every baseplate is hand-checked before it ships, so you're getting a part that's been eyeballed by someone who cares about quality, not just waved through an automated line.
The anodized black finish is durable and low-profile—it won't snag on gear or draw attention, and it resists wear from the friction of mag pouches and range bag tumbling. This is a straightforward upgrade for shooters who want faster transitions and tighter control over their reload sequence, whether you're training for competition, drilling defensive scenarios, or just pushing yourself at the range.
Note: This baseplate is compatible with standard Glock 9mm, .40 S&W, and .357 Sig models but does not fit Glock Models 36, 42, 43, or 48. Check your Glock's model number before ordering to ensure fitment.
| Brand | Rival Arms |
| Compatibility | Glock 9mm, .40 S&W, .357 Sig (Excludes Models 36, 42, 43, 48) |

The Rival Arms baseplate fits standard-frame Glock magazines chambered in 9mm, .40 S&W, and .357 Sig. It does not fit Glock Models 36, 42, 43, or 48. Verify your Glock model number before purchase to confirm compatibility.
The aluminum construction adds weight to the magazine baseplate, which aids in quicker ejection of spent mags during reloads. This can improve reload speed and control, especially during timed range work or defensive training.
CNC milling produces tighter tolerances and more consistent geometry than stamped baseplates, resulting in greater reliability and a more dependable fit across multiple magazines and shooting sessions.
