When Lone Wolf 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 they'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. When using a Gen4 slide you simply remove the installed adapter in the dust cover area of the frame. Using Gen3 slides you leave the adapter in place to fill the gap between the slide and dust cover. The TWC includes the dust cover adapter Mfg: Lone Wolf Dist.
