N23 Special Order Overview:

Craft your slide to meet your tactical needs! Our Special Order process allows you to configure the slide model, optic cut, and coating finish to complete your perfect firearm! Just make a few easy selections with our form and let us do the rest! Within the estimated lead time, we can create your perfect slide made to your custom specifications. All our slides are machined from 17-4 Precipitation Hardened Stainless Steel solid billet right here in Las Vegas, NV. Get yours started today!

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.



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. (N19 slide catalogue used for reference, the designs are the same)


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 dovetail
  • Optic cut depths have been engineered to provide a lower 1/3rd co-witness with suppressor height sights
  • All mounting footprints do not require an adapter plate or sealing plate to mount the optic. Sealing plates or shrouds are still recommended for use by the optic manufacturer for intended applications.

None: No optic cut will be milled onto the slide. Sight mounting features will still be in the factory location. Please note that we will not re-cut an optic cut into the slide once it has been heat treated and hardened.

Aimpoint Acro: 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 SCS: This optic is very light and may require recoil spring adjustment for reliable operation. Slide will ship ready to mount the Holosun SCS at a depth to lower 1/3rd co-witness with factory height sights. Suppressor height sights will provide a full co-witness instead of our usual lower 1/3rd. Special shortened mounting screws will be provided to mount the optic and requires a T10 Torx Drive head to tighten.

Holosun 407C/507C/508T: Slide will ship ready to mount those optics directly. Please use the proprietary screws that Holosun provides 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.

Holosun 407K/507K/EPS Carry*/RMSc Shield: Slide will ship ready to mount those optics directly. For the Holosun optics, you will have to shorten the right-side optic mount screw as they are too long and will run into the plunger rod.

*For the Holosun EPS Carry, you must use their provided mounting plate and shorten the right-side mounting screw to avoid interfering with the plunger rod. Skipping these steps will result in your optic not being tightened down sufficiently and/or operational issues from compressing the plunger rod with the screw.

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 directly. This option includes the 4 corner locating posts and is not compatible with the Romeo 1 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. We’ve had success co-witnessing with the Ameriglo .407” front (Part number GST 407) and the Deltapoint Pro Rear sight. Please use the screws from the Deltapoint Pro box to mount this optic to the slide.

Trijicon RMR: Slide will ship ready to mount the Trijicon RMR or SRO. This footprint is identical to the Holosun 507C footprint but we include special mounting screws for use with the Trijicon optics. 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 Reverse Dovetail: Slide will ship ready to mount the Trijicon RMR but with the dovetail in front of the optic. Note that this option will shift the optic further back on the slide and SRO users will see their optic window run into the rear sight if installed. Ships with a pair of special height mounting screws.

Trijicon RMRcc: Slide will ship ready to mount the RMRcc. This footprint is unique and will only work with the Trijicon RMRcc. Screws are not included with this optic cut; the RMRcc comes with the correct mounting screws in the box.

Vortex Venom (Reverse Dovetail): Slide will ship ready to mount the Vortex Venom with the dovetail in front of the optic due to the larger optic size and curved front geometry. Please be advised that this optic cut will not support the Vortex Viper as we mill the mount perimeter to exact geometry of the Venom. Ships with a pair of special height mounting screws.

Vortex Viper: Slide will ship ready to mount the Vortex Viper. Please be advised that this optic cut will not support the Vortex Venom as we mill the mount perimeter to the exact geometry of the Viper. Ships with a pair of special height mounting screws.


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 a 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.

Norsso standard slide features:

  • Made with 17-4 Precipitation Hardened Stainless Steel
  • Stripped slide only; sights, optics, or other accessories shown are not included with purchase
  • Complimentary channel liner installed for finished slides; attached separately for unfinished slides.

    This is the best made slide. Every detail is perfect, every dimension is spot on. When you can open a product and install it knowing its going to work better than the factory parts thats a good feeling. Keep up the good work.

    G23 Gen 4 Spec Ops Slide

    Posted by Matt on Jan 19th 2023

    Awesome! Precisely milled for RMRcc (perfect fit!) and finished in battle hardened black. Custom job that looks terrific and received in six weeks, even over the Christmas holiday. Couldn’t be happier, and can’t wait to get it to the range. Solid shipping package, and even came with the firing pin channel sleeve installed!

    Norsso N23 Slide in FDE

    Posted by Pat on Oct 2nd 2022

    Great slide, I paired it with a Glock barrel. I didn't want something to crazy in design or a Glock slide that is too basic. The front cuts on this make it easy to do a chamber check and the back cuts are deeper than on Glocks so give a good grip. Everything fit well and worked well at the range. The FDE matches the color on my 80percent arms lower so it looks good too.
