What We Offer
Sig Sauer Slides
BUILT TO PERFORM
When you're searching for Sig Sauer slides for sale, the difference between a reliable firearm and a malfunctioning one comes down to tolerances. At SigSlides.com, every slide we stock is manufactured to OEM specifications — not "close enough" aftermarket alternatives. Our sig sauer slides are tested for proper extractor fit, ejector clearance, barrel lockup, and optic-ready milling before they reach you. Whether you need a complete slide assembly or a stripped slide for a custom build, we carry both.
Sig P320 Slides
The Sig P320 slide is one of the most popular modular pistol slides in the U.S. military and law enforcement. We carry full-size, compact, and subcompact P320 slides — standard and optic-ready (SIG-LOC cut).
Sig P365 Slides
Concealed carry demands precision in a compact form. Our Sig P365 slides — including P365, P365X, and P365XL variants — maintain the tight tolerances required for the micro-compact platform without sacrificing reliability.
Sig P226 Slides
The P226 has served militaries and law enforcement for decades. Our Sig P226 slides are available in standard and optic-ready configurations, machined to the same exacting standards as the original.
Complete Slide Assemblies
Drop-in ready with barrel, recoil spring, and all internal components pre-installed. Ideal for direct replacements or model upgrades
Stripped Sig Slides
Bare slides machined to factory spec — perfect for gunsmiths and builders who prefer to source and fit their own internals.

Common Questions
Sig Sauer Slides FAQ
Are your Sig Sauer slides OEM or aftermarket?
All slides we stock are OEM-specification parts manufactured to Sig Sauer’s original tolerances. They are not third-party aftermarket copies.
Do Sig P320 slides work across P320 variants?
P320 slides are size-specific — full-size, compact, and subcompact use different slide sizes. Verify your frame size before ordering.
What's the difference between a complete and stripped slide?
A complete slide assembly includes the barrel, recoil spring, and internal components. A stripped slide is the bare slide body only, for custom builds.
What optic cuts are available on your slides?
We carry slides with SIG-LOC optic cuts, standard optic-ready cuts, and un-cut (irons-only) options depending on model and variant.
