The Tessera TK-5 Compact is a subcompact semi-automatic pistol chambered in .380 ACP, issued to Tessera Corponation administrative staff who are authorized to carry but whose roles don't warrant a full-size sidearm. The weapon features the same biometric grip lock as the TK-7 but in a frame small enough to fit in a desk drawer or blazer pocket. The finish is a discreet dark gray that matches Tessera's corporate color palette.

The Clerk is the weapon of bureaucrats, accountants, and junior managers who work in Tessera facilities where carrying a sidearm is company policy regardless of role. Most TK-5 carriers have completed only the minimum required firearms qualification and hope never to use the weapon. The heavy double-action trigger and conservative .380 ACP chambering reflect this reality — Tessera designed the weapon to be as difficult to accidentally discharge as possible while still being technically functional.

In Tessera's corporate culture, the TK-5 is a uniform accessory rather than a weapon. Employees drawer it at the start of their shift and holster it without thinking, the same way they clip on their ID badge. The biometric lock means it's essentially a paperweight to anyone who isn't its registered user, which is both a security feature and a tacit acknowledgment that most TK-5 carriers would be more dangerous to themselves than an attacker.
