Lockheed Martin’s GRIZZLY™ Launches First Sanctum™ C-UAS Successfully — A solid piece of kit that’s been turning heads since we added it to our catalog in summer 2025. At 3.1 oz (we weighed it ourselves on the bench scale), it’s got just enough heft to feel substantial without weighing down your setup.

Why This One?
Here’s what we’ve found after handling dozens of these units: the machining is consistently clean, the finish holds up to daily carry, and it fits to spec every time – we inspect each one before shipping. Our customers report it pairs particularly well with extended slide releases for faster reloads.
