Weapons: other; definition of self-defense spray; expand to allow to be dispensed through a cartridge or projectile. Amends sec. 224d of 1931 PA 328 (MCL 750.224d).

HB 5388 amends Michigan's penal code (MCL 750.224d) to update the definition of "self-defense spray or foam device" to explicitly allow dispensing through cartridges or projectiles, rather than only handheld devices. This change directly affects manufacturers, sellers, and users of these devices by expanding permissible delivery methods while maintaining existing chemical limits (e.g., 18% oleoresin capsicum or 8% chlorobenzylidene malononitrile). The bill does not alter the current restrictions on chemical concentrations, prohibited uses, or penalties for misuse. It aims to modernize the legal framework for self-defense devices as technology evolves.
