Why should firearms not be shared among users?

The rationale for not sharing firearms among users centers on the potential for miscommunication about the firearm's condition. Each user may have different knowledge or habits regarding firearm safety, handling, and maintenance. If a firearm is shared, there is a risk that the next person handling it might not be fully aware of its status—whether it is loaded, if there are any existing malfunctions, or how it has been recently handled. This lack of clarity can lead to unsafe situations, increasing the risk of accidental discharges or misuse.

While other options highlight important safety aspects, they do not address the critical issue of communication between users regarding the condition of the firearm. Proper understanding of the specific details concerning a firearm's readiness and safety is essential to ensuring safe handling practices.
