The P40 Warhawk was the first aircraft to don the infamous sharkmouth. It has been seen on other aircraft like the P51 and A10 Warthog. Some creative minds have taken this theme and applied it to firearms. The photo above was done by KM3 Solutions on a customer’s Sig P226 Legion.

Below is a painted Kel-Tec RFB

A Remington sporting the Sharkmouth. The gray underbody two tone really fits the paint scheme.

Of course the Spike’s Tactical Hellbreaker lower has a molded sharkmouth.
