Building with a Polymer 80 Pistol vs Buying a Completed Glock

The build-a-gun scene has been established for some time now, but questions still remain: Should you buy ‘X’ gun, or simply build it? Is building a firearm truly safe? Why not just go to the local store and dump some cash out? Let’s break down the pros and cons of building a polymer 80 Glock vs buying a completed Glock!

Buying a Glock: It’s Easier

…. And that’s about the only “pro” of buying your completed Glock vs building it. Why? Buying a firearm at retail means paying a premium to accommodate the added costs of running an FFL-licensed business. Then you need to pay for a background check, an FFL transfer fee if purchasing online, and any other fees and taxes applicable.

Building a Glock: It’s More Affordable

Building a Glock using a Polymer 80 frame is about as affordable as it gets in the build-a-gun market. Thanks to its polymer construction and relatively simple design, the Polymer 80 frame is inexpensive to produce and easily machined to completion.

Our Polymer 80 Glock kits start at just $160! We currently offer Polymer 80 Glock frames for the Series 17, 19, 23, 26, 27, and 34! Most completed, stripped Glock frames start at around $100 to $125.

Factor in fees, taxes, and paperwork, and you’ve already paid more by buying your frame instead of building your Glock.

Building a Glock: It’s Super Simple

Okay, so filling out a form and standing in line is technically easier but completing your Polymer 80 Glock frame (and assembling it) takes less than a single afternoon. Machining your Glock frame is incredibly simple – all you need to complete your frame is a simple hand drill and hand files.

Each Polymer 80 Glock kit includes the necessary drill bits and an end mill bit for removing the necessary material. Total machining time should take less than one hour – even without power tools. The included instructions and available video tutorials mean you need zero experience!

Building a Glock is Legal in All 50 States

And no paperwork is required. The Bureau of Alcohol, Tobacco, and Firearms has stated that any private individual may build a firearm at home (without the intent of distributing or selling) with no need for conducting a background check or working with an FFL.

Local and state laws may require adherence to certain serialization guidelines, and you may need to submit paperwork to your state legislature before you build your lower – but these requirements are typically no more difficult than any PICS Check or FFL transfer paperwork.

Customize Your Glock as You Build

Buying a Glock off the store shelf means sacrificing certain features or accessories or paying extra. Buying a completed firearm and upgrading it also means needlessly spending more money when you could instead build your piece the way you want.

Your Finished Glock will be High-Quality

Some think building a firearm at home is a gimmick. Others argue the finished product simply won’t hold a flame to a gun produced by a larger manufacturer. This is simply not the case. Each of our Polymer 80 Glock kits is 100% made in the U.S.A by established Glock and holster manufacturer Polymer80.

Each Polymer 80 Glock Kit includes a serialization plate, a stainless steel drop-in rear module, and a stainless steel locking block rail system. Enhanced ergonomic features improve handling and accuracy, and each Polymer 80 Kit is compatible with all Gen 3 Glock uppers and components!
