P320 3.6″ XCompact Optic Ready Slide – Coyote Brown PVD
Upgrade your P320 for maximum concealability with the 3.6-inch Sub-Compact Slide Assembly in factory Coyote Brown. This genuine SIG Sauer replacement upper is the foundation for the ultimate “Micro-Duty” build. Featuring the durable Physical Vapor Deposition (PVD) finish, this slide is designed to withstand the rigors of daily carry while maintaining its distinct FDE/Coyote aesthetic.
Equipped with the PRO optic footprint, this p320 slide is “plug-and-play” for the SIG ROMEO1Pro and Leupold DeltaPoint Pro. Unlike older models, the optic plate is separate from the rear sight, allowing you to maintain your XRAY3 Day/Night sights even when a red dot is installed—providing a reliable co-witness for defensive use.

Why did I wait so long to do this? The optic cut sits nice and low. I’m just happy to finally have a complete setup that works without needing a gunsmith.

Solid lockup, clean lines, and the optic plate screws were actually torqued correctly out of the box. It’s the little things that count.

I was literally shaking when I opened the box because I’ve been scammed twice trying to find this part. Seeing the genuine Sig packaging was such a relief. The slide itself is a work of art, and the XRAY3 sights are bright as heck. You guys have a customer for life.

This little upgrade completely changed the feel of my carry piece. It balances so well now.

The sales guys really saved my bacon. I accidentally ordered the wrong length initially I didn’t realize the 3.9″ barrel wouldn’t flush fit with this 3.6″ slide. They caught the mistake before shipping, emailed me, and swapped it out for the correct one. That kind of attention to detail is rare these days.

Legit. Legit. Legit. Do not hesitate to buy from here.

I don’t even know how that is physically possible, but I love it. The Nitron finish matches my lower perfectly.

Okay, listen up folks. If you are building out a sub-compact, this is the only way to go. I tried a different aftermarket slide before this one and had nothing but extraction issues. Swapped to this factory complete assembly and it ate 200 rounds of cheap ammo today with zero malfunctions. I am absolutely stoked!
David Torres –
Five stars for the packaging alone. It showed up safe and sound, and the optic cut is perfect for my Romeo1Pro.

I honestly thought this website might be too good to be true because the price was actually fair, but I took the risk and I am so glad I did. The slide is authentic, the communication was top-tier, and I finally have my P320 finished. No more searching for shady sellers on forums!

Best purchase I’ve made all year! And it’s only January.
Samantha Alberts –
Big shout out to the shipping department! I needed this before a training class this weekend and you guys made it happen. The slide functioned perfectly during the drills.

Finally, a legit vendor! I spent weeks looking for this specific 3.6″ setup and kept running into “out of stock” notices or sketchy websites. Your sales team was incredibly helpful when I called to verify inventory. It’s refreshing to talk to a human who actually knows what they are selling.

Just got back from the range and wow, this thing runs like a sewing machine. I was worried about the fitment on my X-Compact grip module, but it slid right on without a hitch. The extra serrations make racking it so much easier, too.
Walter –
I cannot believe how fast this got here! After getting burned by a fake site last month that took my money and ghosted me, I was super nervous to order again. But you guys are the real deal! The slide arrived in three days, and the finish is flawless. Thank you for restoring my faith in online gun parts shopping!
