Early guidance highlighted the limitations of a 9 mm handgun for bear encounters, noting its insufficient penetration against a bear’s thick hide and recommending bear spray as the most reliable deterrent. Yelling was described as a supplemental tactic that could intimidate a defensive bear when used alongside spray. Later advice expanded the analysis to physical force and larger firearms. It reiterated that ~~blunt‑force~~ blunt-force attacks are ineffective against a bear’s robust skull and musculature, and it cautioned that even powerful weapons such as an ~~AK‑47~~ AK-47 are not dependable for bear defense due to variables like distance, ammunition type, and shooter skill. The overarching recommendation remained the use of ~~non‑lethal~~ non-lethal deterrents, particularly bear spray, as the primary means of protection. Recent discussions have further differentiated between firearm types. While handguns like the .45 ACP are discouraged because they are unlikely to stop an apex predator, a 12-gauge shotgun loaded with heavy, hard-cast lead slugs or specialized rounds is regarded as a minimum effective choice for stopping an attack. Experts emphasize that effective defense requires understanding bear behavior and recognizing that most encounters can be avoided through proper awareness.
