Best Glock Dovetail Red Dot Mount: Cross-Platform Optic Adapter Guide for USPSA Carry Optics & IPSC Production Optics (CZ Shadow 2, 1911 & 2011) — 2026

The best Glock dovetail red dot mount replaces the factory rear sight and adapts a Trijicon RMR, Holosun 407C/507C, or similar micro-optic to any Glock 17/19/34 — no slide milling, no MOS plate. USPSA Carry Optics shooters made this style the standard because it installs in ten minutes, holds zero, and reverses cleanly. This guide compares Glock dovetail mounting against the equivalent dovetail, optic-ready, and frame-mount systems on CZ Shadow 2, 1911, and 2011 for USPSA Carry Optics, IPSC Production Optics, and Open division.

What a Glock Dovetail Red Dot Mount Actually Is (and Why USPSA Carry Optics Defaulted to It)

A dovetail red dot mount is a single machined plate that slides into the rear-sight dovetail cut on a pistol slide and presents an RMR, DPP, Holosun, or similar micro-optic footprint above it. On a Glock, the rear-sight dovetail is a near-universal feature — every Gen 3, Gen 4, and most Gen 5 slides use the same dovetail geometry — which made dovetail mounts the path of least resistance when red dots arrived in practical pistol shooting. No gunsmith, no MOS plate kit, no slide milling, no down-time. Punch out the rear sight, slide in the mount, torque it down, zero the optic.

That “no permanent modification” advantage is also why USPSA Carry Optics adopted dovetail mounting as the default for Glock 17/19/34 and CZ Shadow 2 (non-OR) competitors. The division rules permit any optic-equipped, slide-mounted red dot, but most working competitors do not want to permanently mill a slide before they have settled on a dot. Dovetail mounting lets you swap optics, sell the gun, or revert to irons in fifteen minutes.

The trade-off is mounting height. A dovetail-mounted optic sits taller than an optic dropped into a factory milled cut, which is why the same Glock crowd is moving toward MOS-cut Gen 5s and the CZ crowd is moving toward Shadow 2 OR (Optic Ready) variants. Both mounting styles still exist side-by-side in 2026, and both are competitive when correctly set up.

Three Mounting Systems Used in USPSA Carry Optics & IPSC Production Optics

Across the four most-asked-about platforms in our Google Search Console data — Glock, CZ Shadow 2, 1911, and 2011 — only three engineering approaches actually exist:

1. Dovetail Mount (Glock Standard, CZ Shadow 2 Equivalent)

Replaces the rear sight. Available for any pistol with a standard rear-sight dovetail. On Glock, this is the dominant aftermarket solution from third-party makers; on CZ Shadow 2 (non-OR), it is the only viable solution short of slide milling. Pros: reversible, no gunsmith, fast install. Cons: highest mounting height of the three; most blocks iron-sight co-witness unless you fit suppressor-height fronts.

2. Direct Slide Cut / Optic-Ready (Glock MOS, CZ Shadow 2 OR)

The slide is factory-milled to accept a footprint plate. Glock MOS uses Glock’s own MOS plate kit; CZ Shadow 2 OR uses a Boss Components precision optic plate that drops into the factory cut. Pros: lowest possible optic height, cleanest sight picture, fastest target transitions. Cons: requires the OR/MOS-cut slide variant, plate must match the optic footprint exactly.

3. Frame-Mounted Optic (1911 / 2011 Universal Multi-Mount)

A bridge-style mount replaces the rear sight or anchors to the slide and accepts an RMR/DPP/Holosun footprint. On 1911 and 2011 platforms, the universal multi-mount approach is dominant because the manufacturer ecosystem is fragmented (Colt, Springfield, Kimber, STI, Staccato, Bul Armory, SVI Infinity, Rock Island) and a single mount that covers all of them is more practical than ten platform-specific SKUs. Pros: fits everything from a Colt Series 70 to a Staccato XC; multi-footprint. Cons: not as low as a milled slide cut, gunsmith recommended for first install.

Glock Dovetail Mount: What Boss Components Carries (and What We Honestly Don’t)

Boss Components is an Adelaide-designed competition parts brand with our deepest catalog in 1911, 2011, CZ Shadow 2, and Tanfoglio platforms. We do not currently produce a Glock-specific dovetail red dot mount — the Glock aftermarket is dominated by US-market makers (Trijicon, OuterImpact, Springer Precision, EGW) and we have not found a manufacturing angle that beats them on price per gram or fit tolerance.

If you shoot a Glock 17, 19, or 34 in USPSA Carry Optics, your two practical paths are:

• Glock MOS Gen 5 with the matching Glock OEM plate kit. Lowest mounting height available on a Glock without third-party slide milling. Required if you want optimal co-witness with suppressor-height irons. Cost: cost of upgrading to MOS slide + Glock plate.
• Aftermarket Glock dovetail mount from a US brand. Works on any Glock generation that takes a standard rear-sight dovetail. Best for shooters who already own a non-MOS Glock and don’t want to upgrade slides. Typical cost: $70-$140 USD.

For the rest of this guide we focus on the platforms where Boss Components has direct, in-stock solutions — and where the dovetail mounting story translates cleanly from Glock’s playbook.

CZ Shadow 2 Dovetail Mount: The Direct Glock-Style Solution for Non-OR Slides

The CZ Shadow 2 Dovetail Red Dot Mount is the closest functional equivalent to an aftermarket Glock dovetail mount. It uses the same engineering principle: replace the rear sight, present an RMR footprint, retain the option to revert to iron sights. We sell it as a bundle ($187.99, save $48) because the firing pin and spring tool are needed for the install on most Shadow 2 generations.

Compatibility extends to CZ 75 SP-01 with the same dovetail geometry, so a single SKU covers two of the most common IPSC Production-class CZ platforms. Mount weight is approximately 40g, comparable to the heavier end of the Glock aftermarket. Optic height is higher than the Shadow 2 OR plate (covered next), but lower than most legacy “riser” mounts and acceptable for Carry Optics.

Division Compliance for Dovetail-Mounted Optics

• USPSA Carry Optics — legal (any optic-equipped slide-mounted red dot)
• USPSA Open — legal (slide-mounted dot is one of two acceptable optic configurations)
• USPSA Production — not legal (no optics permitted)
• USPSA Limited Optics — legal
• IPSC Production Optics — legal (matches Carry Optics intent at international level)
• IPSC Production — not legal
• IPSC Standard — not legal
• IPSC Open — legal

CZ Shadow 2 OR (Optic Ready): The Lower-Mount Alternative

If you bought a CZ Shadow 2 OR variant from new, the smarter buy is the CZ Shadow 2 Optic Ready Red Dot Mount at $89.99. It drops directly into the factory milled cut on the OR slide, which sits the optic 3-5mm lower than a dovetail-mounted equivalent. That difference matters. A lower dot is a faster dot — your eye finds it in the same plane as the slide, the sight picture feels more natural, and target transitions improve measurably under timer pressure.

Compatibility is restricted to CZ Shadow 2 OR (Optic Ready) only — it will not fit standard Shadow 2, SP-01, or any non-OR-cut slide. Footprint is RMR-compatible (Trijicon RMR, Holosun 407C/507C, etc.). Install time is under 10 minutes with a hex key. The full CZ Shadow 2 OR Mount Kit Bundle at $179.99 includes the same supporting parts as the dovetail bundle.

Decision rule for CZ shooters: if your slide has a factory optic cut, use the OR mount. If it doesn’t, use the dovetail mount. There is no third option that performs better.

1911 & 2011 Universal Multi-Mount: Cross-Manufacturer Compatibility

The 1911/2011 ecosystem does not have a single dominant slide profile the way Glock and CZ do. A Staccato P, an STI Edge, a Bul SAS II Ultimate, an SVI Infinity, and a Colt Series 70 all share the same fundamental geometry but differ in slide width, rear-sight cut depth, and tolerance. The 1911/2011 Universal Red Dot Multi-Mount ($139.99) was designed to cover all of them with one SKU.

The mount accepts a wide footprint catalog — RMR, SRO, Holosun 407C/507C/508T/507K, Leupold Delta Point Pro, Sig Romeo 1 Pro / Romeo Zero, Vortex Viper/Venom, Shield RMSc — via included locating pins in multiple sizes (eight pins, sets of two). Mounting screws are not included because the screw thread varies by optic; use the screws supplied with your dot.

For Bul Armory shooters specifically, the Bul Armory 1911/2011 Red Dot Mount is the brand-tuned alternative at $139.99 with a 40g machined billet aluminum body, hard anodized finish, and Bul-specific fit tolerance. Choose the Bul-specific mount if you shoot a Bul SAS II / Ultimate / TAC and want the cleanest possible drop-in fit; choose the universal multi-mount if you have a mixed Staccato/STI/Springfield/Colt arsenal and want one mount that fits all of them.

Why 1911/2011 Doesn’t Use the Glock Dovetail Approach

Glock dovetail mounts work because Glock standardized the rear-sight dovetail across generations and models. 1911/2011 manufacturers did not. A Staccato dovetail cut and a Springfield dovetail cut are not the same depth or width. A bridge-style universal mount that anchors to the rear-sight area but does not depend on dovetail geometry is the only design that fits everything — which is why every serious 1911/2011 maker (us included) sells one.

Mounting Height, Weight & Co-Witness — How They Affect Carry Optics Performance

Three variables drive how a mounted dot actually performs on the timer:

Height. Lower is faster. A direct-cut OR mount sits 3-5mm lower than a dovetail mount. That difference is enough to change which iron sights co-witness through the optic window and how long it takes your eye to find the dot on the draw. For a Glock MOS Gen 5 with the OEM plate, height is the lowest you can get without custom milling. For a Shadow 2 OR with the Boss OR mount, you get the same low-mount benefit. Dovetail mounts (Glock aftermarket, Shadow 2 dovetail) sit higher but still in the “competitive” range.

Weight. A dovetail or universal mount adds 30-45g to the slide. That weight slightly slows the slide’s reciprocating cycle, which most shooters perceive as smoother recoil. The OR-cut plate at 37g is in the same range. None of these mounts add enough weight to require a recoil spring change. If you want intentional recoil tuning, that’s a separate decision — see our CZ Shadow 2 tungsten guide rod or 1911/2011 progressive recoil spring.

Co-witness. A dovetail mount typically blocks factory iron sights. Solutions: (a) leave the irons off, (b) fit suppressor-height irons that clear the optic window. The OR-cut plates and Glock MOS plates allow lower irons that co-witness through the dot window without modification.

Installation Difficulty & Tools by Platform

Glock dovetail mount (aftermarket): 10 minutes. Tools: brass punch + hammer, Loctite Blue, hex driver. Punch out factory rear sight, slide in dovetail mount, lock with set screw, mount optic with supplied screws torqued to spec.

Glock MOS plate: 5 minutes. Tools: hex driver. Remove factory MOS cover, mount Glock plate, mount optic.

CZ Shadow 2 dovetail mount: 10 minutes. Tools: brass punch + hammer for rear-sight removal, hex driver for optic. Often paired with the CZ extended firing pin install (included in the bundle) which adds another 10 minutes the first time.

CZ Shadow 2 OR plate: 5 minutes. Tools: hex driver only. Drops in, screws down.

1911/2011 universal multi-mount: 20 minutes. Tools: brass punch, hex driver, optic-specific screws (use the screws that came with your dot). Slide disassembly required. Gunsmith recommended for first install on an unfamiliar platform.

Complete Your Carry Optics Setup

A red dot mount is the visible upgrade. The supporting parts decide whether the dot tracks consistently. The four upgrades below pair directly with any of the mounts in this guide:

• CZ Extended Firing Pin — Reliable ignition with lighter hammer springs, which most CZ Carry Optics builds use to smooth the trigger. Required if you tune your hammer spring below stock.
• 1911/2011 Extended Firing Pin — Same logic for 1911/2011 race guns running competition hammer/sear setups. Heat-treated stainless steel.
• 1911/2011 Slide Stop Thumb Rest — Pairs with optic-mounted 2011 builds for higher thumb-forward grip and faster slide-stop reload reset.
• CZ Shadow 2 G10 Palm Swell Grips — A dot-equipped Shadow 2 demands consistent grip texture for repeatable dot tracking. G10 with palm swell is the dominant Carry Optics setup.
• 1911/2011 Adjustable Thumb Rest — Combine with the universal multi-mount for a complete 2011 Carry Optics / Limited Optics build.
• CZ Shadow 2 Tungsten Guide Rod — Front-end weight that pairs particularly well with optic-mounted Shadow 2 OR builds because the lower mount + heavier front end makes the dot track flatter.

Frequently Asked Questions

What is the best Glock dovetail red dot mount for USPSA Carry Optics?

For most Glock 17/19/34 USPSA Carry Optics shooters, the optimal path is a Glock MOS Gen 5 with the matching Glock OEM plate kit — it sits the dot lowest and requires no aftermarket parts. If you own a non-MOS Glock, an aftermarket dovetail mount from a reputable US maker (Trijicon, OuterImpact, Springer Precision) is the next-best option at $70-$140 USD. Boss Components does not produce a Glock-specific dovetail mount; we recommend Glock factory MOS over any aftermarket dovetail solution where the slide variant is available.

Will a Glock dovetail mount fit a CZ Shadow 2 or 1911?

No. Glock dovetail mounts are cut to Glock’s rear-sight dovetail geometry, which is unique to Glock. The CZ Shadow 2 dovetail uses different geometry and requires a CZ-specific mount — see our CZ Shadow 2 Dovetail Red Dot Mount Bundle. The 1911 and 2011 platforms use bridge-style frame mounts rather than dovetail mounts — see our 1911/2011 Universal Red Dot Multi-Mount.

Is a dovetail mount lower than an optic-ready slide cut?

No — the opposite. A direct slide cut (Glock MOS, CZ Shadow 2 OR) sits the optic 3-5mm lower than a dovetail mount because the optic drops into a milled pocket rather than sitting on top of a plate. Lower mounting equals faster dot acquisition. If you have an OR/MOS-cut slide, use the matching plate; if you don’t, the dovetail mount is the next-best option.

Which red dot footprints fit the CZ Shadow 2 OR mount?

The Boss Components CZ Shadow 2 OR Mount accepts RMR-pattern footprints — Trijicon RMR, Holosun 407C, Holosun 507C, and similar models. It does not accept DPP, RMSc, or 508T-only footprints.

Which footprints does the 1911/2011 Universal Multi-Mount accept?

The 1911/2011 Universal Red Dot Multi-Mount accepts RMR, SRO, Holosun 407C/507C/508T/507K, Leupold Delta Point Pro, Sig Romeo 1 Pro / Romeo Zero, Vortex Viper/Venom, and Shield RMSc via the included multi-size locating pin set. Mounting screws are not supplied — use the screws that came with your dot.

Are dovetail-mounted optics legal in USPSA Carry Optics?

Yes. USPSA Carry Optics permits any slide-mounted red dot regardless of mounting method (dovetail, MOS plate, or factory milled cut). The same applies to USPSA Open and Limited Optics. Optics are not permitted in USPSA Production or Limited (irons only).

Are dovetail-mounted optics legal in IPSC Production Optics?

Yes. IPSC Production Optics is the international equivalent of USPSA Carry Optics and permits slide-mounted red dots on Production-list pistols, including Glock 17/19/34, CZ Shadow 2 (any variant), and similar service pistols. Confirm your specific pistol is on the current IPSC Production-list at IPSC.org before competing.

Do I need a gunsmith to install a Glock dovetail mount?

No. A Glock dovetail mount, the CZ Shadow 2 dovetail mount, and the OR-cut plates are all DIY installs with a brass punch, hex driver, and 10 minutes. The 1911/2011 universal multi-mount benefits from a gunsmith for first install on an unfamiliar platform because slide disassembly and minor fitting may be required.

Will a dovetail-mounted optic block my iron sights?

Most dovetail mounts replace the factory rear sight, so factory irons will not co-witness. You have two options: (1) shoot the dot only, no irons, which is standard practice in Carry Optics; or (2) fit suppressor-height iron sights that clear the optic window for backup co-witness. Direct-cut OR/MOS plates typically allow lower iron sights that co-witness through the dot window without modification.

Why doesn’t Boss Components make a Glock-specific mount?

The Glock dovetail mount aftermarket is dominated by US-market manufacturers operating at price points and volume we cannot beat. Our manufacturing strength is in 1911/2011, CZ Shadow 2, and Tanfoglio platforms where we hold genuine fit and price advantages. We’d rather be honest about that than ship a me-too Glock product.

Conclusion: Match the Mount to the Platform, Not the Other Way Around

Glock dovetail red dot mounts became the USPSA Carry Optics standard because Glock standardized the rear-sight dovetail across the entire product line — making one mount design fit the whole platform. CZ Shadow 2 borrowed the same logic with a CZ-specific dovetail mount; the OR variant pushed it further with a direct slide cut and lower mounting height. The 1911/2011 ecosystem solved the same problem differently with a universal multi-mount that handles every manufacturer in the category.

Pick by platform: Glock owners on a non-MOS slide should use an aftermarket Glock dovetail mount (US-market makers); Glock MOS owners should use the OEM plate kit; CZ Shadow 2 owners should use either the OR mount or the dovetail bundle depending on slide variant; 1911/2011 owners should default to the universal multi-mount with the Bul-specific alternative for Bul Armory pistols. Pair any of these with a matching extended firing pin and division-legal optic and you have a competitive Carry Optics, Limited Optics, or Open division pistol.
