The Altor pistol fits a number of universal holsters made to accommodate small to medium frame pistols.
One such holster is the Model 036BLK Belt Slide Ambidextrous Concealment holster from Personal Security Products (pictured here). This product has both belt slots and a removeable clip so it can be worn either inside or outside the waistband. It retails for about twenty US dollars ($20.00).
The Altor pistol will also fit into a small cosmetic bag for convenient carry in a handbag or purse.
