Fit, Capacity, and Tactical Value
The PROMAG REPLACEMENT MAGAZINE is designed specifically for the Glock 42 footprint, delivering a 10-round capacity in .380 ACP. That capacity gives a significant advantage in defensive scenarios by increasing available rounds before a reload is required. The magazine’s polymer construction keeps weight down while providing the stiffness needed for reliable feeding under stress.
Why .380 ACP Works for Defensive Use
.380 ACP remains a popular choice for compact defensive pistols due to its controllable recoil and compact ammunition packages. For shooters who prioritize concealment and fast follow-up shots, the combination of a small-framed Glock 42 and a higher-capacity magazine like this one offers a practical balance of carry comfort and on-target performance.
Materials, Finish, and Durability
The black polymer finish resists wear and corrosion and presents a low-reflective profile suitable for tactical carry. Promag has a long history supplying OEM-style and aftermarket magazines; while the model designation is listed as Various, the construction focuses on consistent feed lips, a robust follower, and a reliable spring set capable of maintaining tension for routine use.
At $21.99, this magazine is an economical way to add capacity without investing in a different platform. Regular maintenance—cleaning the feed lips and lightly lubricating the spring—will extend service life and preserve function.

Practical Considerations for Owners
Test any aftermarket magazine thoroughly at the range before relying on it for defensive use. Cycle different brands of .380 ACP ammunition through the PROMAG REPLACEMENT MAGAZINE to ensure consistent feeding. Keep one or two spare magazines configured and carried to reduce reload time under stress.
For Glock 42 owners seeking a cost-effective capacity upgrade with a durable black polymer body and 10-round .380 ACP capability, this Promag magazine is a practical option. Check current availability
