ProMag SPRA18 20-Round Magazine 9mm Springfield Hellcat Blued

The ProMag SPRA18 delivers extended capacity for Springfield Armory Hellcat pistols without compromising reliability or concealability. This 20-round magazine transforms the compact Hellcat into a higher-capacity platform while maintaining the pistol's profile for everyday carry applications.

What Makes This Different

Unlike factory 11-round magazines, the SPRA18 nearly doubles capacity through precision engineering and heat-treated blued steel construction. The magazine features a reinforced steel body that resists deformation under pressure, while the follower design ensures consistent feeding across all 20 rounds. Spring tension remains optimal throughout the entire capacity range, eliminating common feed issues found in extended magazines.

Key Features

• 20-round capacity doubles standard Hellcat magazine count
• Heat-treated blued steel body prevents corrosion and wear
• Anti-tilt follower maintains proper cartridge alignment
• Chrome silicon spring provides consistent tension
• Polymer base plate with witness holes for round counting
• Drop-free design ensures reliable magazine changes
• Compatible with all Springfield Armory Hellcat variants

Range testing demonstrates reliable feeding with various 9mm ammunition weights from 115 to 147 grains. The extended length adds approximately 1.5 inches to the grip, making it suitable for competition shooting, range training, and situations where maximum capacity takes priority over ultimate concealability. The blued finish resists moisture and handling wear better than polymer alternatives.
