Does color matter? A slick pattern may not make your pistol shoot better, but it’ll make it cooler, which will make you want to train more, which will make you shoot better. Gun logic.
Zaffiri Precision has a range of new slide and barrel bundles for the Glock 19 Gen3, Sig Sauer P365-XL, and Sig Sauer P-365-XMacro that just might inspire you to take up a part-time residence at the range.
Between the Multicam black slide and a range of awesome barrel configurations and finishes, there’s something for everyone.
Oh, and they’ll even add a discounted Holosun red dot with a protective shroud.

First up is a ported setup for the Glock 19 Gen3. The complete slide includes an installed upper parts kit, polymer guide rod, and black suppressor-height sights.
Zaffiri Precision’s ported Integrated Blowhole System barrels are available in black nitride, titanium nitride (gold), and stainless.
Want to add a red dot? For a fee, Zaffiri Precision will throw in your choice of a Holosun 407c X2 or 507c X2 with or without an optic cover.

The other Glock 19 Gen3 option caters more to competitive shooters. The complete slide features a slew of weight-relieving cuts on the top and sides. The sights are standard height, with a fiber optic front sight. A polymer guide rod is included.
In addition to flush barrels, you can opt for threaded or a threaded with a row of micro ports along the top. Finishes include black nitride, titanium nitride, stainless, and spectrum (spectrum is not available on the threaded and ported barrel).
A Holosun 407c X2 or 507c X2 with or without a cover is once again available as an add-on.
It’s worth pointing out that these Glock 19 Gen3 slides are also compatible with popular Glock clones, like the Palmetto State Armory Dagger compact and Ruger RXM.

Last up is a complete slide for the Sig Sauer P365XL and P365-XMacro. It features weight-saving cuts on the top and sides, and Sig’s X-Ray3 day/night sights.
In addition to all the barrel styles and finishes (spectrum is only available on the threaded barrel), the P365 also gets the option of a threadless compensator for the P365-XL. Most give you the option to spec your barrel with or without a loaded chamber indicator.
If you want an optic, take your pick from a Holosun 407k X2 or 507k X2 with or without a cover.

“The Multicam Black Bundle was created for builders who want more than just another black slide,” Thom Kuss, executive director of marketing for Zaffiri Precision, said. “This release brings together high-performance machining, aggressive design, and a finish that turns heads, all at a killer value. It’s everything you need to upgrade your Glock or Sig in one package.”
Zaffiri Precision lists a discounted starting MSRP of $399 for these new bundles.

Great write-up! I appreciate how the bundle keeps things optic-ready and lets you choose finishes like spectrum or nitride.
For those of us running suppressed setups, how does the ported or threaded barrel perform accuracy-wise with a compensator on top? Any insights on recoil control or sight picture changes?
Would love to hear if any other shooters have paired it with the P365-XL and how it balances.
Thanks for reading!
