The TCM-10 features completely ambidextrous and intuitive rear-facing toggle switches on each side of the light to operate the momentary-on and constant-on lighting modes. A user-programmable strobe mode and battery-safe mode are available when needed.

Constructed from aircraft-grade 6061-T6 aluminum with a polymer rear housing, the light includes five handgun-specific modular rail inserts (pre-configured with C1 insert for Glock pistols), two spare Allen screws, an Allen wrench, and one CR123 Lithium battery.
