Very handy little tool, this!
Tiny gun, single shot, comes apart and stores in a bag not much bigger than a standard lunch box. Subsonic loads and a suppressor, has it’s place in your kit. Supersonic loads right at same as 7.62×39, no problem with anything you might feel safe to shoot with a 30-30 Winchester. Can’t go wrong, really. Right load for the job, it will do the job.
