The ProMag Sig P320 Compact 9mm Luger 15-round steel blue magazine is a no-frills, cost-effective magazine option for shooters running the compact variant of Sig Sauer's modular P320 platform. If you've got a P320 Compact and need reliable backup magazines for the range, training, or carry rotation without breaking the bank, this steel-bodied mag delivers straightforward function at a practical price point. ProMag magazines have long been the budget-conscious shooter's go-to for high-round-count practice and spare capacity, and this one holds 15 rounds of 9mm in a compact footprint designed to work with the shorter slide and grip module of the P320 Compact.
Built from blued steel, the magazine features a simple, durable construction that resists corrosion in typical storage and field use. The 15-round capacity gives you solid firepower without the bulk of full-size mags, making it practical for both range sessions and defensive carry contexts where magazine count matters. Like all surplus-style magazines, it benefits from actual use—load a few rounds and let it sit for a week or two to break in the spring before relying on it for critical duty.
ProMag has been in the magazine business for decades, and while their products are not OEM, they've earned a reputation for delivering function-first reliability at a fraction of factory pricing. If you're building a rotation of training and backup mags for your P320 Compact, this is a sensible addition to your mag locker.
| Caliber | 9mm Luger |
| Capacity | 15 rounds |
| Material | Blued Steel |
| Fit | Sig Sauer P320 Compact |
| Manufacturer | ProMag |
This magazine is designed for the P320 Compact specifically. While the P320 platform shares the same magazine well across compact and full-size models, ProMag recommends verifying fit and function with your specific firearm before relying on it in duty use.
ProMag magazines are primarily marketed as training and range-use products. For defensive or duty carry, most shooters prefer factory OEM magazines that have been extensively tested and warranted by Sig Sauer. This mag is excellent for practice and backup range rotation.
You receive one 15-round magazine. As with any new aftermarket magazine, it's a good practice to load it with a few rounds and let the spring settle for a week or two before using it in critical situations, or run it through a few hundred rounds of range practice first.
ProMag magazines cost significantly less than factory Sig Sauer OEM magazines and deliver reliable function for training and practice. Factory mags offer longer warranties and have been tested under Sig's rigorous standards; many shooters buy ProMag mags for high-round-count range days and reserve factory mags for duty carry.
