Abstract: Holders usable to secure a firearm include a first plate, a second plate extending from the first plate at a first angle, and an insertable member extending from the second plate at a second angle. The insertable member is adapted for insertion into the barrel of the firearm to stabilize the firearm against lateral movement. Friction between the firearm and the first plate, a trigger guard engaged with the holder, or combinations thereof can stabilize the firearm against vertical movement. Such friction can be created using application of a lateral force against the interior of the firearm barrel using the insertable member, application of a lateral force against the exterior of the firearm using a trigger guard, use of a protruding, compressible, or frictional surface on the first plate, or combinations thereof.

Abstract: Holders for retaining a container for ammunition can include a first portion configured for attachment to a surface, a second portion extending from the first portion, and an insertable member extending from the second portion. The insertable member can be adapted for insertion into the interior of a container for ammunition. To prevent relative movement between the container for ammunition and the first portion, friction can be created between the container and the holder through contact between the insertable member and the container or contact between the body of the holder and the container.
