Caliber or maker? I would recomend cal .22 LR in any format ( Semi Auto or Revolver ) and of a well known makers like Ruger Taurus Beretta S&W and several others
A small caliber hand gun
Yes. Not the best choice, but yes.
For small game hunting, I think so.
Small inexpensive hand gun
You will need to take it to a gunsmith.
38 caliber hand gun
That will vary with the purpose for which you have the gun.
There is no best gun because it depends on too many factors. The best gun for you is whichever gun that fits your hand the best so you can shoot it accurately. Beyond that, a gun for everyday carry must be reliable and be of an adequate caliber for self defense.
No
no. ,22 caliber blanks are far to small, and will fall out of the 8mm gun- which is about .32 caliber.
Relatively small and concealable caliber with enough terminal performance to get the job done with proper shot placement
