What is a major cause of firearm accidents?

Improper storage is a major cause of firearm accidents because it can lead to firearms being accessed by unauthorized individuals, including children or inexperienced adults. If firearms are not stored securely, such as in a locked safe or with trigger locks, they can become easily accessible. This increases the risk of accidental discharges, misuse, or unintentional injuries. Proper storage practices are critical in preventing accidents and ensuring that firearms are kept out of reach of those who should not handle them. Regular maintenance, using brand new ammunition, and reading manuals are all important aspects of firearm safety, but they do not directly relate to the immediate risk of accidental access that improper storage presents.
