Design and compatibility

Made with durable polymer construction, this magazine is dimensioned specifically for the Glock 42. The 10-round capacity for .380 ACP gives users a modest capacity increase while preserving the pistol’s concealable footprint. The black finish matches OEM aesthetics and resists wear from daily carry.

Why polymer matters

Polymer magazines reduce weight and can be more forgiving in adverse conditions. For a pocket or subcompact carry gun like the Glock 42, trimming ounces while keeping a reliable feed ramp and follower geometry is important—this Promag option addresses those priorities.

Caliber and practical applications

.380 ACP remains a popular choice for deep-conceal carry due to low recoil and compact cartridge dimensions. A 10-round .380 ACP magazine is useful for personal defense scenarios, offering additional rounds without adding bulk to a pocket or ankle carry setup.

Maintenance and reliability tips

Routine cleaning and inspection of the feed lips, spring, and follower will extend service life. Use a light brush and mild solvent, then dry and apply a thin film of lubricant only where metal-on-metal occurs. Store magazines unloaded for long-term shelf life to preserve spring tension.

Price is accessible at $19.79, which makes this a cost-effective spare magazine for Glock 42 owners seeking added capacity. The product lists model as Various and is produced by Promag, a known aftermarket parts supplier.
