What is a disadvantage of the sling carry method?

The sling carry method, while useful for transporting a firearm, has the disadvantage of potentially sliding off the shoulder while walking. This can create safety concerns, as a firearm that shifts position can become difficult to manage, and there is a risk of it accidentally falling or being pointed in an unsafe direction. Maintaining a secure grip on the firearm is essential for safety, particularly when navigating uneven terrain or dense brush.

In contrast, the other options highlight benefits or considerations that are not typically regarded as disadvantages of the sling carry method. For example, excellent control in thick brush would be a positive aspect of this method. Similarly, while some may find it uncomfortable during long treks or argue it does not leave a hand free, these factors do not specifically address the risk associated with the firearm potentially sliding off the shoulder, which is the primary concern with this carry method.
