The Lone Wolf Timberwolf Compact TWC-1 is a modular polymer frame for building a compact pistol. It is listed for 9mm, .40 S&W and .357 Sig builds, and it accepts Gen3 and Gen4 Glock 19, 23, 32 and 38 slides. The frame ships without a slide, barrel or sights, so those parts must be added to finish a pistol. Its polymer frame includes interchangeable backstraps and a removable magazine well, so the grip setup can be tailored.

This frame suits a builder who wants a compact, configurable grip frame with interchangeable backstraps and a removable magazine well. A removable dust cover adapter fits the dimensional differences between Gen3 and Gen4 slides, which matters when a builder mixes slide generations. The reduced grip profile is listed as a design feature for a compact build.
