Dropping a match-grade barrel into a Glock is one of the best-value upgrades there is, and two American shops dominate the shortlist. True Precision is the barrel-and-precision specialist — proprietary broach-cut rifling, certified 416R steel, and the widest platform fitment in the business. Zaffiri Precision is the slide-and-barrel house — best known for affordable complete custom Glock and SIG slides with a matching barrel from the same shop. Both are made in the USA, both will out-shoot a factory tube, and both drop in at home. Here is the data, side by side, and which to actually buy.
Short answer: buy True Precision if you want the barrel first — its broach-cut 416R match barrels have a barrel-first pedigree, the broadest platform coverage (Glock, M&P, SIG, Springfield and more), and usually cost a little less on a Glock 19 tube. Buy Zaffiri Precision if you are building or buying a complete custom slide — it is the Glock/SIG slide-and-barrel house, so you can get a matched slide and 416R barrel from one shop, in the finish you want. True Precision wins on pure barrel pedigree and fitment; Zaffiri wins if the barrel is part of a complete slide build. Both are American-made and both are excellent.

The barrels themselves are close on paper — both are certified 416R stainless, both come threaded or flush, both drop in without fitting. The real split is what each company is for: True Precision is a barrel house first, with broach-cut rifling and the widest fitment (including non-Glock platforms), while Zaffiri is a slide house that also makes the matching barrel, so its sweet spot is a complete custom Glock or SIG slide built as one package.
Who each brand is
True Precision was founded in 2016 in Kennesaw, Georgia, to give shooters access to high-quality drop-in match barrels, and it built its name on the barrel itself. Every component is made in-house in the USA, its barrels use a proprietary broach-cut rifling process and certified 416R stainless, and its fitment list is the broadest around — Glock, Smith & Wesson M&P, SIG, Springfield and more — alongside slides and compensators. When people talk about a True Precision, they usually mean the barrel.
Zaffiri Precision, out of Largo, Florida, comes at it from the slide side. It machines custom aftermarket slides for Glock and SIG Sauer from single-billet 17-4 stainless and pairs them with 416R match barrels, all made in-house, so you can order a complete custom slide-and-barrel package — often optic-ready — in the finish you want. Its barrels are excellent in their own right, but Zaffiri’s identity is the complete custom slide.
Barrel quality and accuracy
Both companies build genuine match barrels from certified 416R stainless with tighter chambers and better rifling than a factory tube, and both will tighten your groups noticeably. True Precision leans on its proprietary broach-cut rifling and a barrel-first reputation earned across many platforms; Zaffiri’s 416R barrels are precision-CNC’d in-house to the same material grade. Call the raw accuracy a wash between two quality barrels — give True Precision the nod on sheer barrel pedigree.
Edge: True Precision (slight).
Platform coverage and fitment
This is True Precision’s clearest win. It makes drop-in barrels not just for Glock but for Smith & Wesson M&P, SIG, Springfield and other platforms, so if you shoot more than one pistol brand it can barrel all of them. Zaffiri focuses on Glock and SIG Sauer — deep coverage there, but narrower overall. For the widest fitment, True Precision; if you are strictly a Glock or SIG shooter, both have you covered.
Edge: True Precision.
Slides, complete builds and value
Here Zaffiri turns the tables. Where True Precision is a barrel-first shop (with slides and comps alongside), Zaffiri is built around the complete custom slide — single-billet 17-4 stainless, optic-ready cuts, matched barrel, all from one maker — which is exactly what you want if you are building a slide rather than just swapping a barrel. On the barrel alone, True Precision is usually a touch cheaper on a Glock 19 (about $110–150 versus $135–160), so for a standalone barrel it also wins value; for a complete slide package, Zaffiri is the natural buy.
Edge: Zaffiri (complete builds); True Precision (standalone barrel value).
Where each one wins
Buy True Precision if…
- You just want the barrel: a broach-cut 416R match barrel with a barrel-first pedigree, threaded or flush.
- You shoot more than Glock: the widest fitment around — M&P, SIG, Springfield and more.
- You want the best barrel value: typically a little cheaper on a Glock 19 tube.
Buy Zaffiri Precision if…
- You are building a complete slide: a matched 17-4 slide and 416R barrel from one shop, often optic-ready.
- You want a Glock or SIG custom look: deep slide-and-barrel options in the finish you want.
- You want one package, not separate parts: the complete custom slide is Zaffiri’s whole reason for being.
The honest verdict
Both are American-made 416R match barrels that will beat a factory tube, so you are choosing based on the job. For a standalone drop-in barrel — especially on a non-Glock pistol — True Precision is the pick: a barrel-first pedigree, broach-cut rifling, the broadest fitment, and usually a slightly lower price on a Glock 19. Step over to Zaffiri Precision when the barrel is part of a bigger project: a complete custom Glock or SIG slide, machined in-house from 17-4 stainless with a matched barrel, ordered as one package in the finish you want. True Precision for the barrel; Zaffiri for the complete slide build. Either way you are getting a real match barrel made in the USA.

True Precision vs Zaffiri Precision FAQ
Is True Precision or Zaffiri better for a Glock barrel?
Both make excellent 416R match barrels. For a standalone drop-in barrel with the widest fitment and a barrel-first pedigree, True Precision; if the barrel is part of a complete custom slide build, Zaffiri, since it is the slide-and-barrel house.
Which is cheaper, True Precision or Zaffiri?
On a Glock 19 barrel, True Precision is usually a touch cheaper — roughly $110–150 versus about $135–160 for a Zaffiri — though prices vary by finish and whether it is threaded.
Are True Precision and Zaffiri made in the USA?
Yes, both, and both make their parts in-house. True Precision is in Kennesaw, Georgia; Zaffiri Precision is in Largo, Florida.
Will these barrels fit my Glock?
Both are true drop-in match barrels for the listed Glock models and generations — no fitting or gunsmithing — and both offer threaded (1/2×28) and non-threaded options. Confirm your exact model and generation before ordering.
What is the difference between the two companies?
True Precision is a barrel house first, with the broadest platform coverage (Glock, M&P, SIG, Springfield). Zaffiri Precision is a slide house that also makes the matching barrel, focused on Glock and SIG, so its strength is the complete custom slide package.
Does an aftermarket match barrel actually improve accuracy?
Usually yes, modestly — a match barrel’s tighter chamber and better rifling can shrink group sizes versus a factory barrel, and a threaded version lets you run a compensator or suppressor.
Do they make threaded barrels?
Yes. Both True Precision and Zaffiri offer 1/2×28 threaded barrels (with thread protector) as well as non-threaded flush versions.
Which should I buy for a first Glock barrel upgrade?
For most shooters just wanting a better barrel, the True Precision drop-in is the easy call — great pedigree, widest fitment, good value. Choose Zaffiri if you are building a complete custom slide and want the barrel matched to it.
