Pro Tip: Special orders that match a stock configuration will be fulfilled first before placing stock online. This is the best way to get a stock slide reserved instead of waiting for a stock refresh that may not come.
Model:
This is where you choose the design that best meets your needs. We offer a wide range of models that blend functional features into attractive, precision machined designs. For additional information on each model click here to see their respective web pages.
Optic Milling:
We machine the optic cut directly onto the slide without the need of an adapter plate. Please consider this choice carefully as this decision is not reversible once the slide has been milled to that specification. Using different optics on footprints than the ones specified below is at your own discretion and compatibility is not guaranteed.
The following is applicable for all mounting footprints unless stated otherwise:
- All mounting footprints are placed in front of the rear sight dovetail (irons back), unless the option says "Reverse Dovetail" (irons forward), or other modifiers
- All mounting footprints do not require an adapter plate to mount the optic. Sealing plates or shrouds are still recommended for use by the optic manufacturer for intended applications.
Additional info on optic cut mounting holes, iron sight recommendations, and other notes can be found on this webpage here.

None: No optic cut will be milled onto the slide. Iron sight dovetails will still be in milled into the slide unless specified otherwise. Please note that we will not re-cut an optic cut into the slide once it has been heat treated and hardened.
Aimpoint Acro/Steiner MPS: Slide will ship with the specific rail feature to mount the Aimpoint Acro C-1, C-2, P-1, or P-2 optics directly to the slide with the included optic hardware. The Steiner MPS can be used on this footprint but there will be a gap from the front of the footprint to the MPS. This footprint is not compatible with the Holosun 509T.
Holosun 509T: Slide will ship with the specific rail feature to mount the 509T directly with recoil stop slot. This footprint is not compatible with the Aimpoint Acro footprint; the Acro rail is much thinner.
Leupold Deltapoint Pro: Slide will ship ready to install the Deltapoint Pro. This option includes the 4 corner locating posts and is not compatible with the Romeo 1 Pro or RomeoX Pro. Unique to this cut is the removal of the rear dovetail to allow space for the Deltapoint Pro’s rear sight attachment. Suppressor height sights are not tall enough to co-witness with this optic. Co-witnessing is achieved by using the DeltaPoint Pro rear iron sight and a Dawson precision .455" tall front sight, Part # 021-543.
RomeoX Pro/Romeo2/Holosun SCS320: Slide will ship ready to mount the RomeoX Pro (not compact) and the Holosun SCS320, includes the rear dovetail for co-witnessing with the optic. Please use the M4 screws that are provided with the optic to mount to the slide. For the Romeo2, you’ll need taller than suppressor height sights, .455” front, .440” rear height will work (we do not carry these).
Trijicon RMR/Holosun 507C: Slide will ship ready to mount those optics directly. Please use the short set of screws provided with the optic. This footprint is our default option for stocked slides so be sure to check our online store inventory before placing a special order with this option to avoid an unnecessary lead time.
Trijicon RMR/Holosun 507C Reverse Dovetail: Same as the normal Trijicon RMR cut but with the iron sight dovetail in front of the optic, or in an irons forward arrangement.
Trijicon SRO, Rear shift (no rear irons) – Slide will ship ready to mount the Trijicon SRO. This cut has the rear sight dovetail removed to allow a rearward shift of the optic cut, allowing the front of the optic to remain behind the breech face. With proper extraction, this eliminates the brass from being ejected into the optic.
Slide Finish:
We offer a variety of different options for finishing/coating your slide after it has been milled. Please review the following options to see which best meets your tactical needs.
Unfinished (Media Blasted): Select this option if you wish to get it coated from another vendor. We media blast the slide with roughness to make it ready for coating. The slide will be shipped in an unfinished state not ready for operation. It is inadvisable to use the slide in this condition and may void your warranty if issues occur.
Black DLC: Slide will arrive with a coated solid black Diamond-like Carbon finish.
Battle Hardened Black DLC: Slide will arrive with our distressed black DLC finish with highlighted edges.
Satin Stainless Steel: Slide will arrive with a semi-polished, non-directional soft satin stainless steel finish (uncoated). Low reflectivity and a clean, uniform look set this premium finish apart from others while maintaining cosmetic longevity. Frequent cleaning and lubrication are required for this finish since there is no coating.
Cerakote: All other colors not identified above are achieved through Cerakote. Slide will arrive with a single color Cerakote coating of your choice offering unmatched corrosion, chemical and durability performance. Cerakote options cannot be combined to create patterns, camo, or battleworn finishes. If you need something more custom, we can provide the slide in an unfinished state for you to provide your coater.

Amazing
The best aftermarket slide I've ever purchased. I've purchased several aftermarket slides but this one is the best smooth gliding, like the slide is slipping on butter

Bentham Custom Slide
I recently ordered a Bentham custom side and overall I am very happy with it. Customer service was EXCEPTIONAL! The patience and understanding with me was needed, greatly appreciated and still unbelievable. The only hang up I have with the slide is the slanted cut off the dust cover. It leaves the spring exposed which forces me to purchase a full size grip. Other than that the product itself is of quality and great craftsmanship.

Reptile C, DLC coating, 509T optics cut
I am satisfied with the machining and coating of this slide. I haven't had a chance to test it yet, but the quality seems impeccable. It was difficult to find an aftermarket slide that checked every box on my wish list; for example, I was hoping to find something with no windows, and perhaps with knurling instead of traditional serrations, not only because of the possibility of an improved grip, but also because the uneven surface has the potential to diffuse the glare of sunlight reflecting off the top of the slide. The Reptile C does have windows, but they are minimal. It is not knurled either, but the serrations are quite aggressive and grippy, and it's possible that the angled surfaces at 12oclock will do just as well to diffuse sun glare. I will have to wait for summer to make that determination.
