Description
The Lone Wolf Timberwolf Full Size frame is what you reach for when you love the reliability of a Glock but never got along with the factory grip. Lone Wolf reworked the design to run 9mm, .40 S&W, and .357 SIG, and the biggest change you'll feel is the grip. It sits with a straighter, more 1911-like angle that points naturally, and folks who shoot a mix of platforms tend to notice their sights land closer to on target right out of the holster. The grip diameter runs slim too, which is part of why it's a favorite among people who find a stock Glock a little chunky in the hand.
What the Timberwolf Full Size Fits
This full-size frame accepts Gen3 and Gen4 slides from the G17, 17L, 22, 24, 31, 34, 35, and 37. The dust cover comes with an adapter already installed, so if you're running a Gen3 slide you leave it in place to fill the gap, and if you're going Gen4 you simply pop it out. That flexibility is a big part of the appeal, since you can pull the slide off an existing pistol, drop it on the Timberwolf, and end up with a gun that fits your hand better without buying a whole new setup.
Dialing In the Fit
Because this is the BUILT version, it ships with a stack of Lone Wolf internals already installed, including the trigger group, connector, springs, extended slide stop, locking block, and a reversible Gen4-style magazine catch. The reversible mag release is a genuine plus for lefties who get stuck with narrow Gen3-only parts on a lot of aftermarket frames. It also comes with interchangeable backstraps and a removable magazine well, so you can tune the feel and either flare out the mag opening for faster reloads or strip it off for a cleaner carry profile.
Building With the Timberwolf Full Size
The fit and finish earns steady praise, with builders describing it as solid as an OEM frame while feeling noticeably better in the hand. Assembly is straightforward if you've spent any time inside a Glock, since your remaining factory parts follow standard fit and function. Whether you're putting together a range toy, a competition longslide, or a woods carry gun, this frame gives you a proven foundation to build on.

Frequently Asked Questions
What slides will the Timberwolf Full Size frame work with?
It accepts both Gen3 and Gen4 slides from the Glock 17, 17L, 22, 24, 31, 34, 35, and 37. The dust cover has a pre-installed adapter that stays in for Gen3 slides and comes out for Gen4. That covers 9mm, .40 S&W, and .357 SIG builds depending on the slide and barrel you pair it with.
Does the built version of this frame come with the trigger and internals installed?
Yes. The BUILT version ships with a full set of Lone Wolf fire control parts already in place, including the trigger group, connector, springs, extended slide stop, locking block, and a reversible Gen4-style magazine catch. You supply the slide and complete the build with your remaining factory parts, which follow standard Glock fit and function.
How is the Timberwolf grip different from a stock Glock?
The main draw is a straighter, more 1911-like grip angle along with a slimmer grip profile. People who don't get along with the factory Glock angle often find this one points more naturally and lets them get a higher, more consistent hold. The interchangeable backstraps let you fine-tune the feel even further.
Is the magazine well removable on the Timberwolf Full Size?
It is. The flared magazine well drops off easily if you want a slimmer profile for carry, or you can leave it on for faster, funneled reloads at the range or in competition. Same goes for tailoring the backstraps to your hand.
