Design and fit for Glock 42

The PROMAG REPLACEMENT MAGAZINE is designed specifically for the Glock 42, providing a factory-style fit for reliable insertion and seating. Its stated compatibility with the Glock 42 platform simplifies parts selection—no guesswork on follower geometry or catch engagement. Given the product listing identifies the model as Various, it’s positioned as a straightforward replacement option for shooters who need an extra 6‑round magazine for everyday carry.

Caliber and practical applications

The magazine is built for .380 ACP, a cartridge commonly chosen for subcompact defensive pistols like the Glock 42. .380 ACP offers manageable recoil in a very small package, making it suitable for close-range defensive scenarios and for shooters seeking controllability in a pocket-size carry gun. A 6‑round capacity is consistent with the Glock 42’s original configuration and maintains the pistol’s slim footprint.

Operational considerations

Spare magazines reduce reload time and increase tactical options during a defensive encounter or range session. Keep magazines clean, inspect the follower and spring for wear, and rotate your carry mags periodically. At $16.99 apiece, the PROMAG REPLACEMENT MAGAZINE makes it affordable to maintain multiple loaded spares for daily carry or training plates.
