True Precision is one of the brands that helped turn the aftermarket Glock barrel from a niche accessory into a category of its own. If you have seen a Glock or SIG P365 wearing a gleaming gold or copper barrel poking out of the slide, there is a good chance it was a True Precision. But the looks are the smallest part of the story — what True Precision really sells is a match-grade, drop-in barrel that shoots better than the factory part and will happily run lead and reloaded ammo. Here is who they are and what is worth buying.
Who True Precision is
True Precision helped turn the aftermarket Glock barrel into a category of its own. Beyond the gleaming gold and copper PVD looks, its match-grade barrels for Glock and the SIG P365 are cut to tighter tolerances for better accuracy than a factory barrel.
True Precision (note the hyphen in true-precision.com — the non-hyphenated domain is an unrelated plastics company) is a relatively young American manufacturer, reportedly founded around 2016, based in the Acworth/Kennesaw area of Georgia. It is a privately held, pistol-focused parts maker with a strong “American Made Precision” identity, and it machines its components in-house in the USA from US-sourced material. In a market full of imported barrels, that domestic, vertically integrated approach is a real part of the brand’s appeal.
What True Precision makes
Match-grade barrels — the calling card
The barrels are what made True Precision’s name. They are cut with a proprietary broach-cut rifling — conventional lands and grooves rather than the polygonal rifling in a factory Glock barrel — from certified 416R match-grade stainless. That rifling choice has a practical payoff: unlike factory polygonal barrels, broach-cut barrels are rated for cast-lead and reloaded ammunition, which matters a lot to high-volume and reloading shooters. True Precision markets increased chamber support over factory with a SAAMI-spec chamber — an honest way to describe it: more support than stock for reliable feeding, not an ultra-tight match chamber that fusses about ammo. Barrels come threaded (usually 1/2×28 in 9mm) and non-threaded, drop-in fit, in finishes including black nitride, gold TiN, copper TiCN, DLC, and bare stainless.
Axiom slides and more
The Axiom series slides are the other hero line — 17-4 PH stainless, optic-cut for popular micro red-dot footprints, with lightening windows, front scallops, and angled rear serrations, primarily for the Glock 43/43X and SIG P365 families. True Precision also makes compensators (Cobra, Y-Type, S-Type), triggers, grip modules, complete “Full Build” pistols, and even a customizable .22 rifle, the TP/22.
Build quality and finishes
Everything is US-made and machined in-house. Barrels are 416R stainless; slides are heat-treated 17-4 PH stainless. The finishes are not just cosmetic — the black nitride is a QPQ treatment that case-hardens into the steel rather than sitting on top of it, and the TiN and DLC coatings are durable PVD finishes. The brand sits in the upper-mid to premium “match-grade drop-in” tier and backs parts with a limited lifetime warranty to the original purchaser. The combination of real performance and eye-catching finishes is exactly why a True Precision barrel-and-slide combo is such a popular micro-compact build.
How True Precision compares
The aftermarket Glock barrel field has a few clear reference points. KKM Precision is the older accuracy gold standard — very tight match chambers and a competition pedigree — and tends to edge out True Precision on pure ransom-rest accuracy; it is the “serious precision” pick. Zaffiri Precision is the closest peer: another mid-priced, drop-in, finish-forward brand, and the choice between them often comes down to finish, price, and availability. Faxon is the broad value all-rounder with huge platform coverage. True Precision’s spot is the mid-premium “looks great, shoots better than stock, eats lead ammo, drops right in” tier — above budget barrels like Lone Wolf, roughly level with Zaffiri, and below KKM or Wilson Combat for absolute match accuracy.
Who should buy what
- Adding a suppressor or comp: a threaded True Precision barrel (1/2×28 in 9mm).
- Accuracy upgrade plus lead-ammo capability: a non-threaded match barrel — great for reloaders whose ammo factory polygonal barrels do not love.
- Red-dot micro-compact build: an Axiom slide on a Glock 43/43X or SIG P365, optic-ready and lighter than stock.
- Anyone who wants visual pop: the gold, copper, or DLC finishes on a carry or range gun.
Why broach-cut rifling matters
The single most important thing to understand about a True Precision barrel is the rifling, because it drives everything else. Factory Glock barrels use polygonal rifling — smooth, hill-and-valley bore geometry that is durable and easy to mass-produce, but that the manufacturer specifically warns against using with cast-lead bullets, because lead fouls polygonal bores quickly and can spike pressures. True Precision’s broach-cut rifling uses conventional sharp lands and grooves, the same approach used by traditional match barrels. That does two things for you. First, it grips the bullet cleanly and consistently, which is where the accuracy gain over a stock barrel comes from. Second, and just as important to a lot of shooters, it lets you safely shoot cast-lead and reloaded ammunition — which makes high-volume practice and reloading dramatically cheaper. If you have ever wanted to run cheap cast reloads through your Glock, an aftermarket land-and-groove barrel like True Precision’s is the standard way to do it.
Building a P365 or Glock 43X
One of the most popular things people do with True Precision parts is build out a micro-compact carry pistol, and it is worth walking through why the combination works. On a SIG P365 or Glock 43X, a True Precision barrel and an Axiom optic-cut slide together turn a basic carry gun into a tuned, red-dot-ready package. The Axiom slide is cut for popular micro red-dot footprints, lightened with windows and scallops, and finished to match the barrel — so you get a lighter reciprocating mass (which can soften the felt impulse on these snappy little guns), an optic mount, and a coordinated look in one upgrade. Add a threaded barrel if you want a compensator down the road. It is a build path that has become almost a default in the micro-compact world, and True Precision is one of the names that made it accessible.

True Precision FAQ
Are True Precision barrels drop-in, or do they need fitting?
They are designed to drop into factory pistols (such as Glocks) without gunsmithing.
Can I shoot lead or reloaded ammo through them?
Yes. Unlike factory polygonal Glock barrels, the broach-cut land-and-groove rifling is rated for cast-lead and reloads.
What thread pitch are the threaded barrels?
Most 9mm models are 1/2×28, the common pistol suppressor and compensator thread.
Where are they made, and is there a warranty?
Made in the USA from 416R stainless, with a limited lifetime warranty to the original purchaser for manufacturing defects.
Will it actually improve accuracy over my factory barrel?
Generally yes versus stock, thanks to a tighter SAAMI-spec chamber with increased support and match rifling — though gains over an already-good factory barrel can be modest at typical defensive distances.
Does True Precision make anything besides barrels?
True Precision is best known for its match Glock and P365 barrels, but it also makes optic-ready slides, compensators and other small parts to build out a custom pistol around one of its barrels.
What finishes do True Precision barrels come in?
Beyond standard black nitride, True Precision is known for eye-catching PVD finishes in gold, copper and other colors, plus threaded and non-threaded options, so you can match a barrel to the look of your build.
Will a True Precision barrel fit my Glock?
True Precision makes drop-in barrels for most popular Glock models and the SIG P365 by generation and size, so match the barrel to your exact pistol and you can install it with no fitting.
