Design and fit for Glock 43

The PROMAG REPLACEMENT MAGAZINE’s polymer construction keeps weight down while resisting corrosion common to metal aftermarket mags. Designed specifically for Glock 43 compatibility, its single-stack 10-round layout preserves the slim profile owners expect from that platform while giving an extra round of defensive capacity. The matte black finish blends with factory aesthetics and concealment holsters.

Why 9mm Luger matters

9mm Luger remains the standard defensive caliber for its balance of capacity, controllable recoil, and effective terminal performance with modern defensive loads. A 10-round magazine for Glock 43 lets shooters retain a slim grip and reliable ergonomics while adding practical on-hand capacity for personal defense or range practice.

Field performance and handling

Polymer followers and spring specs influence feeding reliability; Promag’s aftermarket mag is built with those parts in mind to reduce hang-ups common to cheaper clones. For carry use, the additional round can be decisive, while the polymer body reduces weight in a loaded spare. At $21.99, this magazine represents a budget-friendly option for users who want extra capacity without sacrificing concealability.
