Revolvers have a frame, a cylinder rotatably mounted to the frame and defining a plurality of passages, each passage having a chamber configured to receive a cartridge, each passage defining a bore forward of the chamber and configured to closely receive a bullet and retain propellant pressure to expel the bullet, and each bore having a forward aperture. A firing facility may be connected to the frame rearward of the cylinder and registered with a selected one of the passages, the revolver being free of elements forward of the selected one of the passages. The frame may include a ring defining an aperture configured to receive a first finger. The ring may be free of a trigger. A finger rest may be outside of the ring and configured to engage a second finger. The finger rest may be an elongated arcuate extension having a free end away from the frame.

A handgun support device includes a handgun rest for supporting at least a portion of a grip of a handgun therein, where the handgun rest includes a wall portion, and a back support for at least a portion of a back side of the grip of the handgun, the back support protruding from a back side of the wall portion and including a hole or gap to allow a thumb of a user to be placed through an opening thereof to support the handgun against the wall portion of the handgun rest with the user's fingers and opposing thumb. The handgun rest further excludes a front support for at least a portion of a front side of the grip of the handgun. Still yet, the handgun support device includes a rigid structure extending from the handgun rest for being held against an external support.
