About this product
A Polymer80 handgun is a semi-automatic pistol with an 80% completed polymer frame requiring user finishing. It features front and rear angled slide serrations, thumb/accelerator cut, and a double-undercut trigger guard. This model serves as a platform for custom builds where final machining and assembly are performed by the end-user.
What is a Polymer80 handgun used for?
A Polymer80 handgun is used for building custom firearms where the user completes the final 20% of frame machining. It requires milling out specific polymer sections and drilling pin holes using a jig. The completed frame accepts Glock-compatible slides and components for customized performance.
How does the Polymer80 handgun compare to a Lone Wolf Timber Wolf frame?
The Polymer80 handgun weighs 14.2 ounces compared to the Lone Wolf Timber Wolf's 16.8 ounces. The Polymer80 features more aggressive 40-degree angled serrations versus Timber Wolf's 25-degree pattern. Timber Wolf offers pre-milled frames while Polymer80 requires full user completion with provided jig tools.
What does it weigh and what are the dimensions?
The unfinished Polymer80 frame weighs 14.2 ounces with dimensions of 7.3 inches long, 5.1 inches tall, and 1.3 inches wide. The trigger guard undercut provides 0.6 inches of clearance versus standard Glock's 0.4 inches. Frame rail slots require milling to 0.118-inch depth specifications.
Who is this NOT for?
This is not for shooters lacking machining tools or gunsmithing experience. Completion requires a drill press or rotary tool, vise, and measuring calipers. Users must dedicate approximately 3-4 hours for proper milling and fitting. Those seeking ready-to-shoot firearms should consider our completed LR-308 receivers instead.
What's in the box?
The box contains one 80% polymer frame, aluminum jig with alignment pins, and drill bit set. It includes three specific drill bits: 3mm for pin holes, 4mm for starter holes, and 6mm for recoil spring channel. No locking block or rails are included—these must be sourced separately for final assembly.
Is the Polymer80 handgun worth it at $469?
At $469, it justifies cost for builders wanting specific frame modifications unavailable commercially. The double-undercut trigger guard and accelerator cut would cost $120-180 aftermarket on standard frames. For those valuing time over customization, our finished anodized lowers provide better immediate value.

Frequently asked questions
- Is it compatible with Glock 19 slides?
- Yes, it accepts Gen 3 Glock 19 slides and components. You'll need to source a complete upper parts kit and locking block separately. Frame rail dimensions match OEM Glock specifications within 0.002-inch tolerance.
- Does it fit standard Glock holsters?
- No, the frame dimensions differ from factory Glocks due to the accelerator cut and trigger guard undercut. You'll need custom holsters from companies like Tier 1 Concealed or Safariland that accommodate modified frames. Allow 2-3 weeks for holster fabrication.
- How long does shipping take?
- Shipping takes 3-5 business days via FedEx Ground for in-stock items. Signature confirmation is required for all firearm component deliveries. Processing time adds 1-2 business days before shipment tracking is provided.
- Can I return it if I mess up the milling?
- No, returns are not accepted once machining has begun. The frame is considered altered and non-transferable per ATF regulations. We recommend practicing on polymer blanks before attempting the actual frame completion.
- Does this work with Timney Alpha triggers?
- Yes, it accommodates aftermarket triggers including Timney Alpha and Apex Tactical models. Trigger housing dimensions match Glock Gen 3 specifications. Installation requires standard punch set and 0.154-inch pin drift.
