Description
The Lone Wolf Timber Wolf TWF is Lone Wolf Distributors' full-size take on the Glock-pattern frame, molded in black polymer and sized to run Gen3 and Gen4 G17, 17L, 22, 24, 31, 34, 35 and 37 slides. That range of compatibility means the same frame can become the base for a 9mm, .40 S&W or .357 SIG build depending on which slide assembly you pair it with. It ships completely stripped, so there's no trigger, trigger housing, slide stop or magazine release installed, which means you'll want a completion kit or a set of compatible fire control parts on hand before you start putting the pistol together.
The Timber Wolf TWF Grip Feel
Even though the outside dimensions line up with a standard full-size Glock, this frame is reshaped to feel noticeably smaller in the hand. Lone Wolf squared off the trigger guard and cut a deep undercut where it meets the grip, which opens up room for your support hand and helps get rid of that pinched knuckle feeling after a long session behind the gun.
Running Gen3 or Gen4 Slides on the Same Frame
Inside the dust cover sits a small removable adapter, and that piece of plastic is what lets this one frame run either slide generation. Leave it in place for a Gen3 slide, pull it out for Gen4, and you avoid the usual mismatch issues that come from mixing recoil spring setups. The outside of the dust cover doubles as a short two-slot rail, enough real estate for a compact light.
Setting Up Your Timber Wolf Frame
The backstrap is interchangeable between flat and curved profiles, so you can dial the grip angle in closer to a 1911 or keep it closer to a stock Glock feel. The magazine well is removable too, which comes in handy if you decide to swap it for a flared or flush-fit style down the road. Since Timber Wolf backstraps share their mounting system across the full-size and large frame lines, finding replacement parts or trying different configurations later on stays simple.

Frequently Asked Questions
What Glock slides fit the Timber Wolf TWF frame?
This frame is built for full-size Gen3 and Gen4 Glock 17, 17L, 22, 24, 31, 34, 35 and 37 slide assemblies. The removable adapter in the dust cover is what allows it to switch between generations, so you leave it in for Gen3 slides or pull it for Gen4.
Does the Timber Wolf TWF come with a trigger or other internals?
No, this version ships completely stripped with no trigger, trigger housing, slide stop, locking block or magazine release installed. You'll need a separate frame completion kit or compatible fire control parts to finish the build.
What magazines work in this frame?
Since it's built around the full-size Glock 17/22 footprint, it runs standard Glock-pattern magazines matched to whatever caliber slide you install, so 9mm mags for a 9mm build, .40 S&W mags for a .40 build, and so on.
Can I adjust the grip size or angle on the Timber Wolf TWF?
Yes, the backstrap swaps between flat and curved options to fine tune grip angle and circumference for your hand. The magazine well is also removable if you want to change that setup once the build is finished.
