When reliability matters for concealed carry or range training, magazine selection can be as important as the firearm itself. A durable, well-fitting spare magazine reduces malfunctions and speeds reloads under pressure, which is why many Glock 43 owners look for a simple, affordable replacement that keeps function consistent with their pistols.

PROMAG REPLACEMENT MAGAZINE is a polymer magazine compatible with a Glock 43. It has a 10-round 9mm Luger capacity and a black finish, offered at an accessible price of $21.99.

Design and compatibility

The PROMAG REPLACEMENT MAGAZINE uses a polymer body designed to fit the Glock 43 magazine well without modification. Polymer construction keeps weight down while resisting corrosion and dings common to metal magazines. The black finish blends with the factory magazine aesthetics for a discreet spare that sits comfortably in a pocket, mag carrier, or backup pouch. As a product from Promag—an established aftermarket parts maker—the model listing shows Various configurations, making it a practical choice for Glock 43 owners who need a straightforward spare.

Capacity and caliber advantages

With a 10-round 9mm Luger capacity, this magazine aligns with the Glock 43’s compact profile and common legal limits. The 9mm Luger remains a top choice for self-defense and range use due to wide ammunition availability, manageable recoil, and proven terminal performance when paired with modern defensive loads. A single extra 10-round magazine is often the easiest way to increase on-hand rounds without changing carry ergonomics.

Polymer magazines are forgiving in drops and everyday handling; pairing one with proper maintenance—periodic cleaning and inspection of the feed lips and spring—helps ensure consistent feeding. For those who rotate carry equipment frequently, stocking multiple low-cost, reliable magazines is a sound strategy.
