The DPP footprint

How to identify a DeltaPoint Pro cut without a caliper

Take the cover plate off the slide, or turn the optic over, and read the recess in this order.

1. Screw holes: two. They sit on the long axis and the optic screws pass down through its body into the slide, a screw-through mount. If the optic instead clamps sideways with a single cross bolt, you are looking at an ACRO or Holosun 509T interface and nothing on this page applies.
2. Recoil sockets: four, at the corners. Two forward, two rear. Four is the number that rules out the RMR pattern, which puts two bosses forward of the screws and nothing behind them.
3. Body length: about 46mm, not about 40mm. This is the step most charts skip, and it is the one that decides between this pattern and the RMSc pattern, because those two share both counts. A DeltaPoint Pro sized optic covers a full size slide window; a 40mm micro sits noticeably shorter on the same cut.

One warning about counting on the plate rather than on the optic. The standard defines four sockets, but some mounts are made with only two of the four pins present. A plate with two pins is still a DeltaPoint Pro plate. Count the sockets on the underside of the optic, which are always four, not the pins on whatever it is sitting on (optics-trade.eu).

The reference part is the Leupold DeltaPoint Pro itself (leupold.com). Three more that are easy to find in a shop and built to the same pattern: the Vortex Defender XL (opticsforce.com), the EOTech EFLX (riflesupply.com) and the Bushnell RXS-10 (bushnell.com).

The screw description and the 46mm figure trace to footprint guides, not to a Leupold drawing (optics-trade.eu, opticsplanet.com). Screw centre spacing, thread depth, socket diameter and window size are not published here. No window dimension is recorded for any of the 15 optics on this pattern, and no manufacturer drawing carrying those figures has been read into the dataset. The rule on this site is to print a null rather than a guess, so use the screws that shipped with your optic and the length its maker specifies for your slide.

Look-alikes that will not interchange

DPP against RMSc. The pattern pair most often treated as one. Same two screws, same four corner sockets, different size class: the RMSc record in this dataset states outright that the pattern exists at about 40mm for micro optics and about 46mm for full size ones, and that a slide cut for one length will not take the other. DPP is the 46mm end. The practical consequence is in the counts: 80 of the 196 pistols here are cut for RMSc at the factory against 2 for DPP, because the industry mills the micro version onto carry slides. The RMSc hub carries that side.

The Shield RMS, specifically. It shares the screw and socket pattern at the larger size, but its locating posts are recorded as about 0.4mm undersized, so it seats loose rather than drop-in (shieldsights.com). This dataset files every Shield Sights optic under RMSc and records no DPP fit for any of them. Treat a loose-but-close fit as a maintenance problem, not a mount.

DPP against Docter or Noblex. Two screws and four corner sockets on both, and this dataset publishes no socket spacing for either, so there is no counting test that separates them. Say that plainly rather than pretend otherwise: match the optic against its own maker’s spec page. The line runs straight through product families, which is how people get caught. The Vortex Venom is recorded on the Docter pattern (egwguns.com) while the Venom Enclosed is recorded on DPP (dnwoutdoors.com). The Crimson Trace CTS-1250 is Docter here too, on Crimson Trace’s own page (crimsontrace.com). The Docter hub carries the 6 optics on that pattern.

DPP against RMR. Four corner sockets against two forward bosses, which is a clean test in both directions. The RMR hub carries 33 optics against 15 here, and 7 factory-cut pistols against 2. Both patterns are plate-dependent in practice, and a slide that takes one rarely takes the other: only the Ruger RXM and the Shadow Systems MR920 accept both directly.

DPP against the Holosun K pattern. Different count and different size class: Holosun K is a two-screw, two-lug carry pattern with 5 optics and 26 factory-cut pistols. Nothing on that list mounts here.

DPP against MOS, OSP, VIS, AOS, LOPMS and the rest. Those are plate systems, not footprints. A slide stamped MOS or OSP has no footprint milled into it at all: the plate decides. See Glock MOS and the plate section on this page.

One disagreement worth naming. The pattern description printed above the tables on this page lists parts the industry associates with the DeltaPoint Pro cut, including a Sig Romeo1Pro and a Holosun SCS 320. This dataset holds no optic page for either, and where it does hold a page the page’s own sourced footprint governs: the CTS-1250 is filed under Docter, and the three Holosun SCS pages here are built for a specific maker’s pocket rather than this pattern. A reputation is not a fit. If an optic is not in the list on this page, this site is not claiming it mounts here.

How a plate gets you to DPP

2 pistols in this dataset are cut for the DeltaPoint Pro at the factory. 110 more take a DPP optic through a plate, with no overlap between the two groups: 112 of the 196 pistols here, or 57.1 percent, can carry one of these optics one way or the other.

In words, a plate path works like this. The slide is milled for a proprietary interface that is not a footprint at all. A plate drops into that interface and its top face carries a real footprint. Fit the plate that presents DPP and the slide behaves, for optic-buying purposes, like a DPP slide. The plate table for each system lives on that system’s own hub, not here.

Every plate system in this dataset offers a DeltaPoint Pro path. All 15 of them, covering 12 pistol brands. Only the RMR pattern matches that, and it is the strongest single argument for this footprint: whatever optics-ready pistol a reader already owns, the plate exists. The largest paths, by pistol count:

• Glock MOS, 16 pistols. The factory MOS adapter presenting the DeltaPoint Pro pattern (opticsplanet.com).
• SIG P320 X-series, 16 pistols. A modular adapter on the X-series cut (outerimpact.com).
• S&W M&P CORE, 14 pistols. A CORE plate presenting DPP (chpws.com).
• FN 509, 12 pistols. The Low-Profile Optics Mounting System with a DPP plate (chpws.com).
• Beretta APX A1, 10 pistols. The 90-Series and APX A1 optic plate kit (beretta.com).
• Walther PDP 2.0, 10 pistols. The Gen 2 plate (optics-spot.com). The PDP 1.0 plate reaches one more.

Nine further systems present DPP on smaller pistol sets: CZ P-10 OR and HK VP9 OR (chpws.com), Canik METE (outerimpact.com), Springfield Echelon VIS (store.springfield-armory.com), Taurus TORO (shoptaurus.com), Springfield XD OSP (store.springfield-armory.com), Springfield AOS (springfield-armory.com) and the Ruger factory plate (outerimpact.com). Every path and its pistol list is in the plate section further down this page.

Two costs come with a plate: height above the bore, and one more interface that can loosen under recoil. This dataset records no DPP-pattern optic that ships with its own adapter plate in the box, so on a plate-system pistol the plate is a separate purchase. If your slide is cut for DPP directly, that is the better mount.

How to choose a DeltaPoint Pro optic

No prices on this page and no rankings the data cannot support. The live offer links beside each optic in the list below carry current pricing; the copy here does not, because a number written into prose is wrong within a week. What the data does support:

• Every optic on this pattern reaches the same 112 pistols. All 15 of them, identically. Choosing between DPP optics is therefore a question about the optic, never about compatibility: the pattern decides where it mounts and every page on this list mounts in the same places.
• The enclosed emitter share is the best of the big three patterns. 5 of the 15 pages here are enclosed designs, a third of the pattern, against 3 of 33 on RMR and 8 of 30 on RMSc. Those five are 5 of the 27 enclosed optics in the whole dataset. If a sealed emitter is the requirement and you are choosing a slide or a plate today, this pattern is the strongest full size option here. The enclosed five: Bushnell RXE-MR1 (bushnell.com), EOTech EFLX CE, Sig Sauer Romeo-X Enclosed Pro (grayguns.com), Vortex Defender-ST Enclosed Solar and Vortex Venom Enclosed.
• Five brands, and two large ones are missing. Bushnell 4 pages, Sig Sauer 4, Vortex 4, EOTech 2, Leupold 1. Neither Holosun nor Trijicon builds an optic recorded on this pattern here, which is the opposite of the RMR list where Holosun alone accounts for 16 of 33 pages. If brand availability at your local counter matters, check that before committing a slide to this cut.
• Buy the mount before the optic. With 2 factory-cut slides in 196, the realistic question is not which DPP optic to buy but whether your pistol’s plate system offers the path. All 15 do, so the answer is yes, and the plate is the first purchase.
• Where a slide choice is still open, the Ruger RXM accepts DPP, RMR and RMSc optics directly, 78 compatible optics in all, and the Shadow Systems MR920 accepts DPP and RMR, 48 in all. They are the two most flexible DPP-cut slides in the dataset because they are the only two.
• Check the optic page, not the brand. Vortex splits its own Venom line across two patterns. Each optic page lists the pistols it fits and links the source for that claim.

Provenance, stated plainly: 4 of the 15 optic pages on this pattern have been verified against a manufacturer page, part of 41 of the 100 optic pages site-wide. The footprint record itself rests on three third-party footprint guides rather than a Leupold specification document. Nothing here is verified against a physical sample. Confirm against your own slide before you spend money.
