The F2 Gun is a compact, small-frame revolver known for its lightweight design and reliability. Typically chambered in .22 LR or .38 Special, it offers a balance of portability and firepower. Its snub-nose barrel (usually 2-3 inches) makes it easy to conceal, while its simple double-action/single-action mechanism ensures smooth operation. Popular for self-defense and backup use, the F2 is praised for its durability and affordability.
