The Palm Pistol is an ergonomically innovative single shot double action only defensive firearm chambered in 9mm that may be fired using either hand without regard to orientation of the stock. Suited for home defense, concealed carry or as a backup gun. It is also ideal for seniors, disabled or others who may have limited strength or manual dexterity. Using the thumb instead of the index finger for firing, it significantly reduces muzzle drift, one of the principle causes of inaccurate targeting. Point and shoot couldn’t be easier.
I do wonder how useful a single shot 9mm is but they are pretty up front about the disadvantages of their product in the product specification PDF. It will be interesting to see if this goes into production.
This type of palm held squeeze to fire pistols have been around for quite some time. James has a write up about them here.
