Pocket pistols like the Sig P238 demand magazines that combine compact profile with uncompromising reliability. For daily carry and backup roles, a spare magazine should be rugged, feed consistently, and return quickly to service after repeated use. The PROMAG SIG P238 addresses those priorities with construction choices aimed at durability and dependable function.

PROMAG SIG P238 is a 6-round replacement magazine compatible with a Sig P238 chambered in .380 ACP. It is constructed from heat-treated nickel-plated steel and fitted with a black polymer follower, lock plate, and base plate. The spring is wound from chromesilicon wire and heat-treated for strength and reliability, delivering a compact 6-round capacity at an MSRP of $20.99. Shop this product

Design and Construction

The PROMAG SIG P238 uses heat-treated nickel-plated steel for the body, giving corrosion resistance and a smooth feed ramp against the cartridge. The black polymer follower and lock plate reduce friction and help maintain consistent alignment of rounds during cycling. Attention to materials—especially the chromesilicon wire spring that is heat-treated for strength—means the spring retains tension through multiple reload cycles, preserving reliable feeding in a small-package magazine.

Why .380 ACP Works Here

The .380 ACP is a common choice for micro-compact pistols like the P238 because it balances manageable recoil, adequate terminal performance for close-range defense, and allows for thin, concealable slide/frame profiles. A well-built 6-round magazine ensures you have immediate spare capacity without adding bulk to a pocket or holster setup.

Fit, Performance, and Tactical Use

Fitment is key with aftermarket magazines. The PROMAG SIG P238 is tailored for Sig P238 platforms and engineered to seat cleanly, lock the slide open when empty, and release smoothly on reload. For tactical carry, use the polymer base plate for easier magazine extraction from a pouch and regular function checks during practice to confirm consistent feeding. View product details and pricing

Maintenance and Field Tips

Keep the magazine clean of lint and debris, lightly lubricate the spring and follower contact points, and cycle dummy rounds to verify spring tension. The nickel plating resists surface corrosion, but routine inspection of the chromesilicon spring and polymer components will extend service life.

For shooters who rely on the Sig P238 for concealed carry, the PROMAG SIG P238 offers an affordable ($20.99) spare that emphasizes durable materials—heat-treated, nickel-plated steel, a chromesilicon spring, and polymer components—designed to keep you ready.
