HOLOSUN 507K CUT SLIDE FOR SIG P365XL

HOLOSUN 507K CUT SLIDE FOR SIG P365XL Reviews & Ratings

Ergonomic Enhancements + Mounting Slot for Popular Holosun Red Dot


The Brownells slide for the SIG P365 XL comes with a built-in mounting slot for the Holosun 507K red dot sight. The affordable, feature-rich, ultra-compact 507K is the perfect red dot for the compact, versatile SIG Sauer P365 XL pistol platform. Although some mount footprints for other manufacturers' red dot sights can work for the Holosun 507K, the mounting slot on our slide is cut to fit the exact dimensions of the sight. This results in a rock-solid sight installation that will not shift under recoil.


Our Holosun 507K Cut Slide for SIG P365 XL offers all the quality, robustness, and ergonomic enhancements of our popular slides for Glock®pistols. It is perfect for upgrading an existing factory P365 XL or for your own custom build. Each slide is precision machined from a billet of stainless steel for precise fit to the SIG P365 FCU and grip module. A tough non-reflective Black Nitride finish protects the slide from surface wear and corrosion.


Front and rear cocking serrations are wide and deep enough to give you a non-slip grasp to rack the slide under any conditions. Edges have been beveled and de-horned to prevent snagging on a holster or clothing. Supplementing the Holosun 507K mounting slot are factory dovetails for front and rear "iron" sights as backups should your red dot fail (which is pretty unlikely!).


The Brownells Holosun 507K Cut Slide for SIG P365 XL is available with a Window cut into the forward top of the slide for weight reduction and because it just looks cool!


Brownells Gun Tech™ Note:
Our Holosun 507K Cut Slide for SIG P365 XL consists of the bare slide only. You will need to retain your pistol's existing internal parts or use aftermarket parts.

365XL w/ window
Fantastic slide for the price, be hard pressed to find a better deal.

Very impressed
For the price, the slide looks nice. It’s made with the same material as the boujee ones, for a lot less. The finish is also smooth. Racking the slide, I don’t feel any grittiness.

Solid
It's a perfect clone. It's all the holsters. The romeo zero sits on it until I can afford a holosun 407. Overall extremely happy with my purchase. Would recommend.

Great Slide
Purchased two of these slides to go to red dot setups on my P365's. The use the newest extractor and run great. The nitrde coating is very well done and durable. I have a particular holster that wears on slides quickly and they are still holding up. The optic cut is perfect for the Holosun 407k/507k red dots leaving almost no play in the setup before you bolt it down. The slide racks easy and simply runs. Finally, the slide cuts are deeper than the factory slides making manipulation a breeze. Pair it with their Brownells Match grade barrel and you have a really nice build. Yes I bought that as well.

Sig P365xl Slide & XS night sights
The slide is exactly what I wanted. Good fit, tight lock up. Now for the XS night sights, the front sight has no glow of any kind. The rear sight, on the right side low light compared to the left. Brownells customer service was awesome. Thank you Brownells.
Would you recommend this? Yes, I would recommend to a friend

It's so so.
This is a nice slide but because they modified the dimensions it doesn't fit most holsters especially with a light on it.

Rusty slide
The slide arrived rusty. Rust in the striker chamber. Rust in the inside surface of the slide where the barrel fits. Rust developing in the dovetail sight channels. I figured it might an unlucky slide, so I exchanged it for another of the same model. The 2nd slide also arrived rusty in the same places. Really ugly. I guess the batch was bad? I’m returning the slide. I want my money back for such poor quality, twice.

Poorly machined
QC issue: The slide has a chip in it straight out of the box making the recoil spring assembly malfunction by catching on the deformity. I would send it back, but I really don't want a replacement slide from this company. There are other companies to do business with...

Rear sight cannot be installed
I broke a quality sight pusher and 3 brass punches trying to get a stock sig p365 rear sight into the dovetail. The only thing I can think of is the rear sight dovetail must be out of spec. Do not recommended.

Not the Brownells quality I expected
Ordered along with the Brownells barrel. Barrel is great. Slide? Not so much. The left side threaded mounting hole was not properly tapped. The screws would go in about 1/2 way and then stop. I don’t have an M3-0.5 tap so I tried using new screws to finish the tap. I got quite a bit of shavings out of the hole but eventually got a screw in all the way. And before you comment, no, I didn’t cross thread the screws. It was tapped properly only 1/2 way and the screws would easily go in up to that point. Then came the second issue. The slide is bigger than the factory slide and won’t fit any holster I own. I wanted to love this slide. The serrations are better than OEM. The fit of every other part was perfect. And the finish was excellent. But the fact that I couldn’t mount an optic to a slide meant for mounting optics was just too much. Plus I couldn’t get it in and out of my holsters. So I returned it.
