When you carry a compact pistol like the Sig P290, magazine reliability and discrete capacity are critical factors. A thin, well-made spare magazine can make the difference between a smooth reload and a malfunction under stress. Reliable feeding, durable materials, and a correct fit to the pistol are priorities for duty, home defense, and everyday carry setups.

PROMAG SIG P290

Shop this product to add a low-profile spare for your Sig P290.

Design and compatibility

The PROMAG SIG P290 is a blued steel magazine engineered to be compatible with a Sig P290 chambered in 9mm. Its 6-round capacity keeps the magazine compact and suited to the pistol’s subcompact dimensions. Promag is a recognized aftermarket parts brand, and the listing indicates model options as Various, reflecting fitment choices and small manufacturing runs that support popular compact pistol platforms.

Why 9mm works for compact defensive pistols

9mm remains the practical balance of size, recoil management, and terminal performance for concealed-carry pistols. For the Sig P290 platform, a dedicated 9mm magazine ensures correct feeding, reliable extraction, and consistent chamber pressure handling. The 6-round capacity is a common compromise for minimal grip footprint while retaining adequate defensive rounds.

Field use and maintenance

Blued steel construction provides toughness and abrasion resistance; keep the PROMAG SIG P290 wiped and lightly lubricated at the feed lips and spring for long service life. Inspect the spring tension and feed lips regularly—especially if the magazine is carried loaded for extended periods. A maintenance routine of cleaning, visual inspection, and function checks will keep the spare feeding like the factory unit.

At $17.99, this magazine is an affordable way to increase your reload options without adding bulk. View product details and pricing to confirm fit for your serial-number-specific P290 variant.

For those who prioritize a low-profile carry setup, the 6-round blued steel magazine provides a durable, cost-effective spare that pairs well with a Sig P290 chambered in 9mm.
