N320C (3.9" Barrel length) 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.

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.


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 risk.

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.

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. This footprint is not compatible with the Holosun 509T or the Steiner MPS optic.

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/RMSc Shield/Romeo Zero: Slide will ship ready to mount those optics directly. For the K series optics, you may have to shorten the right-side optic mount screw as they are too long and will run into the extractor depressor rod.

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. 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.

Romeo 1 Pro: Slide will ship ready to mount the Romeo 1 Pro. Please use the screws that are provided with the optic to mount to the slide.

Trijicon RMR: Slide will ship ready to mount the Trijicon RMR. 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. 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.

Trijicon SRO – 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 your slide after it has been milled.

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: Slide will arrive with a coated solid black finish.

Battle Hardened Black: Slide will arrive with a distressed black finish with highlighted edges. Scroll through the product pictures for more detail.

Titanium Carbon-Nitride (TiCN Copper): Slide will arrive with a satin copper finish. This coating is not as durable as the black or Titanium Nitride coating and will show wear sooner.

Titanium Nitride (TiN Gold): Slide will arrive with a satin gold finish.

Satin Stainless Steel: Slide will arrive with a semi-polished, non-directional soft satin stainless steel finish. 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 of your choice offering unmatched corrosion, chemical and durability performance.

    Reptile slide for p320

    Posted by Garo on Jul 25th 2022

    Wanted to build a compensated compact upper for my legion. This thing looks so great and feels fantastic. Functions just as good if not better than stock. Had norsso slap on some night fision suppressor height sights on it as well. Would definitely order again and recommend to anyone.

    509T Slide

    Posted by Jeremy on May 13th 2022

    Great custom slide for my 509T. It's almost impossible to get a cowitness unless you get a custom slide for the 509t. Notsso did a great job.

    Special Order Bentham Slide

    Posted by Michael Hanley on Dec 8th 2021

    This was my first aftermarket slide that ive bought so i was skeptical that it wouldnt turn out like i imagined but i was sure proven wrong when i received it. It was perfect! It said 6-8 week lead time for special orders and it was at my door in a week. I ordered the battleworn finish and was worried it would be too overdone, wrong again! This has been an amazing experience, and a great first impression for this company and a true testament to their reputation and craftsmanship. I look forward to my next battleworn special order slide for my Glock 45.

    Reptile c

    Posted by Joshua isaacson on Feb 23rd 2021

    I love the way this slide looks and feels. I had to do a Special order for the reptile C due to them not having them in stock no big deal shipping was fast!!! The only thing I wish is that they would sent the slide with a cover plate. I know on the web site it clearly states that it is just the slide but I think adding the cover plate would have been the Icing on the cake

    This is an amazingly beautiful and awesome slide. I found this to enhance an already incredible firearm. My gun is now smooth as silk, accurate to a tee, and just flat out awesome. I couldn’t have asked for better customer service. Norsso, long may you devastate

    The ultimate in design and craftsmanship!!

    Posted by Kevin Wilhelm on Sep 27th 2020

    My Experience with Norsso was Exceptional from the moment that I called/placed my order.... until my slides were shipped/received. When I called Norsso to inquire about the different custom options for my G23 and P320 slides... they took the time and patience to answer all my questions/concerns in great detail in a professional and respectful manner. The answers they provided to my questions left no doubt in my mind that manufacturing and highest possible quality slides isn't simply a job, but rather a passion of those at Norsso. When I received my package with my custom slides, they were package in a way that they would not be damaged during shipment/foam padded boxes... it was explained to me that the timeline/lead time posted on their website of 6 to 8 weeks was only an estimate and probably worse case scenario. I'm not sure where in a process the P320 slide that I ordered was at the time I place my order, but I do know that the Glock G23 slides are made to order... It was also explained to me that they send the slides out to have the DLC finish performed. From start to finish.... Having said that, the process was completed and I received notification of shipment exactly one month after I place my order.... even the package was delivered a day earlier than forecasted... The bottom line, Norsso manufacturers some of the most amazing slides on the market... Their custom millwork, fitment and finish are truly second to none!! This was my first purchase/experience with Norsso, but I can say with 100% certainty that it won't be my last.
