ProMag SIG08 8-Round .45 ACP Magazine for Sig Sauer P220 Blued Steel

The ProMag SIG08 delivers reliable feeding and consistent performance for Sig Sauer P220 pistols chambered in .45 ACP. This 8-round magazine maintains the original capacity while providing an affordable backup or replacement option for competitive shooters and everyday carry enthusiasts.

What Makes This Different

Unlike factory magazines that command premium prices, the ProMag SIG08 offers the same 8-round capacity at a fraction of the cost without sacrificing reliability. The blued steel construction provides corrosion resistance comparable to OEM magazines while maintaining the precise tolerances required for consistent feeding. Heat-treated steel components ensure long-term durability under repeated loading cycles.

Key Features

• 8-round capacity matches factory specification for .45 ACP cartridges
• Blued steel construction with corrosion-resistant finish
• Heat-treated steel spring maintains consistent tension over time
• Precision-machined follower ensures smooth cartridge presentation
• Drop-free design allows rapid magazine changes
• Compatible with all Sig Sauer P220 variants in .45 ACP

The SIG08 performs reliably across temperature extremes and feeding conditions that matter for serious use. Competition shooters appreciate the consistent lock-back function and smooth feeding during rapid-fire strings. The magazine functions equally well for concealed carry applications where reliability cannot be compromised. The blued finish resists moisture and handling wear better than painted alternatives.
