Lone Wolf’s Timberwolf Full-Size frame (Lone Wolf part no. LWD-TWF3-BUILT) is a complete, ready-to-shoot frame built across 9mm, .40 S&W, and .357 SIG, redesigned so it fits in the hand like a much smaller pistol despite accepting full-size Gen3 and Gen4 Glock slides. The TWF accepts G17, 17L, 22, 24, 31, 34, 35, and 37 slides, with a removable dust cover adapter that lets it switch between Gen3 and Gen4 slide fitment. It ships complete with the dust cover adapter, a removable magazine well, and interchangeable backstraps, so whether you want a competition longslide build, a backwoods carry gun, or a slim 9mm for personal protection, this frame is ready to run.
