Runner Up: Remington RM380 Micro
Although the Remington RM380 Micro is compact enough to fit in your pocket, it does have a longer barrel than usual for this class of gun.
As a result, the RM380 Micro offers durability, impressive bullet velocity and reliable accuracy. A nice perk of this gun is the ambidextrous magazine release, which makes it a good choice for lefties.
The grip is also noteworthy, and this is very important if you truly wish to quickly pull a gun out of your pocket and be ready to shoot without hesitation.
