Tyrant Cnc
The Tyrant CNC Hellcat magazine extension adds 3 rounds of 9mm capacity to your Springfield Hellcat or Hellcat Pro, giving you a practical bump in firepower without a complete magazine overhaul. Built from 7000-series aluminum and precision CNC machined, this extension is finished with a bead-blasted, hardcoat anodized coating that stands up to daily carry and use. It's designed to work seamlessly with your existing OEM magazine spring—no special tools, modifications, or gunsmithing required.
What sets this extension apart is Tyrant CNC's NoBak springer plunger technology. Installation and removal are straightforward, and the extension stays locked in place even under rough handling or if your mag gets dropped. The sleek profile integrates naturally with your Hellcat's lines, so you're not adding bulk for that extra capacity. Whether you're running USPSA competitions, heading afield, or just want one more round in the pipe for self-defense, this is a no-fuss upgrade that actually works with your gun as it came from the factory.
This extension does not fit 10-round magazines, so verify you're pairing it with a compatible Hellcat or Hellcat Pro mag. Tyrant CNC's reputation in the custom Hellcat community is solid—they know the platform and build to spec. If you're already comfortable with your pistol and want to squeeze a few more rounds into your standard magazine without compromise, this is a straightforward, proven add-on.
