1. A gun comprising:
a grip component comprising a window portion that is transmissible to infrared electromagnetic radiation but largely or entirely non-transmissible to visible electromagnetic radiation;
multiple proximity sensors, each proximity sensor of the multiple proximity sensors comprising a respective controller configured to generate an output in response to determining that a signal satisfies a threshold, wherein at least one proximity sensor of the multiple proximity sensors comprises a laser proximity sensor that is positioned and oriented such that the laser proximity sensor is capable of transmitting infrared electromagnetic radiation through the window portion of the grip component, wherein the signal is representative of infrared electromagnetic radiation returning through the window portion of the grip component; and
a processor that is communicatively coupled with each proximity sensor of the multiple proximity sensors, wherein the processor comprises multiple cores and is configured to perform a boot procedure in response to receiving the output, the boot procedure comprising:
executing a first set of instructions by a first core of the processor to identify boot media stored in memory of the gun and verify an authenticity of the boot media based on a cryptographic key, and
executing a second set of instructions by a second core of the processor based on the authenticity of the boot media, wherein the second set of instructions comprises the boot media.
