When we first launched the original Timberwolf frame, one of the first questions was “when will it be available in 9mm, .40 S&W, and .357SIG?” That time is now, because we’ve revamped and upgraded the design to bring you the Timberwolf Compact. The first thing you’ll notice is that the TWC fits in your hand like a much smaller pistol. The TWC-3 and TWC-1 accept Gen3 and Gen4 G19, 23, 32, and 38 slides.
