The Tessera TK-7 is a striker-fired semi-automatic pistol chambered in 9x19mm, issued as the standard sidearm to Tessera Corponation's security and administrative enforcement divisions. The weapon features a proprietary biometric grip that locks the firing mechanism unless the registered user's palm print is detected — a feature Tessera markets as 'personnel security' but which critics note also prevents anyone from testifying about the weapon's performance by firing it themselves.

The TK-7 is a competent but unremarkable pistol elevated by its Tessera branding and biometric lock system. Build quality is good, accuracy is acceptable, and the trigger has the slightly mushy character common to striker-fired designs. The biometric system adds 0.2 seconds to the first shot — a delay that has been the subject of multiple internal review boards after field incidents.

Every Tessera facility in GLMZ has racks of TK-7s in its security office. The weapon is so associated with the corponation that carrying one outside Tessera employment is considered a social signal — either you're a former Tessera employee, or you want people to think you are.
