Typical for this kind of optic, where nothing is publishedWith standard-height irons: No co-witness. Standard-height irons sit well below any pistol red dot window and are only usable with the optic off. Suppressor-height sights fix that; a different optic won't.With suppressor-height irons: Unlikely to co-witness. An enclosed emitter on a plate puts the window above suppressor-height irons. Plan on optic-only, or sights taller than suppressor height. This optic's window runs small (19.5 × 14.7 mm), so a front sight slightly off the ideal height is more likely to miss it. That's the typical case for this kind of optic, not a guarantee: pistols don't standardize sight and optic heights the way rifles do.
On this modelMilled for the RMSc pattern: no plate for an RMSc-pattern optic.
How this slide mounts an opticMilled for the Shield RMSc pattern: an RMSc-pattern optic bolts straight on. S&W doesn't say a Holosun K optic does, and C&H sells a plate to put one on this slide, so this site lists the plate. Nameless Arms, which re-machines these pockets for K optics, says S&W cuts them sloping 0.5 to 0.75 degrees toward the muzzle, enough that some optics run short of elevation.

What to order, and how to fit it
The fit checker's build sheet for this pair, assuming sights of unknown height. Open it in the fit checker to set your sights, work out screw length from your own caliper readings, or copy it as text.
Rather not do it yourself? Mounting an optic is a short bench job for most gun shops and gunsmiths. Buy the parts under "Parts to order" and take this sheet with you.

Fasteners: which bag
You don't buy these. Screws come with the pistol, the optic and the plate, and they look alike. The thread is tapped into the slide or plate (the optic only has a clearance hole), so they decide the thread, not the optic.
| Joint | Thread | Comes from |
|---|---|---|
| Plate → slide | #6-32 | Supplied with the plate. If your pistol shipped with a cover plate, keep its screws apart from these: plate screws and cover-plate screws are different lengths. |
| Optic → plate | per plate maker | Supplied with the plate, not the optic. Most mistakes happen here. The screws in the optic's box are cut for mounting straight onto a slide; a plate changes the stack, so the plate maker supplies the right pair. If your plate came without screws, measure before you buy. |
On the bench before you start
- Torque wrench — set to the figure in your optic's manual
- Driver bits — T10, fully seated so they don't round the head
- Calipers — for the screw length check below
- Blue removable threadlocker — Vibra-Tite VC-3 or Loctite 242. Never red.
- Degreaser — isopropyl or brake cleaner
- A parts tray — you'll have three bags of look-alike screws
- Witness-mark paint or lacquer — so you can see if anything moves later

Sequence
- Clear the pistol. Drop the magazine, lock the slide back, look and feel the chamber, then do it again.
- Remove the factory cover plate and set its screws aside. They are not optic screws.
- Degrease the slide pocket, both faces of the plate and the optic base. Oil under a plate lets it move.
- Seat the plate on the slide, check it sits flat with no rock, and fit its screws with blue threadlocker.
- Torque the plate to spec, bringing the screws up evenly rather than one at a time.
- Seat the optic on the plate's recoil posts, fit the optic screws with blue threadlocker, and torque to the optic spec.
- Let the threadlocker cure before firing (check the bottle; usually a few hours to overnight).
- Confirm zero at your working distance, then re-check torque after the first 100–200 rounds.
Before you fire it
- Screw length checked dry: it must not bottom out on the slide or reach the striker channel.
- Optic sits flat with no rock, and the screws pulled up evenly.
- Torque set with a wrench, not by feel. Witness-mark the screws so movement is visible later.
- Threadlocker cured.
- Function check, then zero confirmed live.
Screw length is the one that hurts
Too long and a screw bottoms out on the slide or reaches the striker channel; too short and it strips under recoil. This sheet gives the thread but can't give the length, which depends on your exact plate and optic stack. Test-fit dry and count threads.
Sight co-witness
Answered above: co-witness with standard and suppressor-height irons.
Confirm the firearm is unloaded before any work on the slide. Mounting an optic is gunsmithing: stay within your competence and use a gunsmith when a job is past it. Provided as-is with no warranty; you use this at your own risk. Prices are approximate street-price bands from September 2026. Torque and fitment figures come from manufacturer documentation; confirm against the current manuals for your pistol, optic and plate before installing.
