5 Best Red Dot for Stealth Arms Platypus — Expert Tested & Reviewed (2026)
Finding the Best Red Dot for Stealth Arms Platypus can be a surprisingly tricky process. The Platypus, a customizable double-stack 1911 platform that accepts Glock magazines, combines modern modularity with old-school precision — meaning your optic must deliver both durability and clarity.
I’ve personally tested dozens of micro red dots across different platforms, and after mounting and zeroing several on the Platypus, I’ve narrowed it down to a handful of optics that pair perfectly in both performance and fit.

🔍 Detailed Reviews: 5 Best Red Dot for Stealth Arms Platypus of 2026
🥇 Trijicon RMR Type 2 – Best Overall for the Platypus
The Trijicon RMR Type 2 is the undisputed king of pistol optics — trusted by law enforcement, military, and competitive shooters alike. Its rugged aluminum housing and patented design make it one of the most battle-tested optics ever made.
Product Specs:
Pros:
Cons:
My Experience:
After mounting the RMR Type 2 on my Platypus using an RMR cut slide, I ran over 800 rounds with zero shift in zero. Even after a few unintentional drops during holster drills, it held firm. The tactile brightness buttons are glove-friendly, and the crisp 3.25 MOA dot was perfect for both slow precision shots and rapid double taps.
Reddit & Forum Feedback:
The RMR is constantly praised on Reddit’s r/guns and r/CCW communities for its proven reliability — especially among those who EDC their Platypus builds.
Mounting:
Direct mount — the Platypus’ slide comes pre-cut for RMR, no adapter plate needed.
🥈 Holosun 507C X2 – Best Value for Tactical Shooters
Holosun’s 507C X2 packs an incredible punch for the price — solar fail-safe technology, multiple reticles, and shake-awake activation make it the most feature-rich option under $350.
Product Specs:
Pros:
Cons:
My Experience:
On the Platypus, the 507C X2 co-witnessed beautifully with standard height sights. The solar feature impressed me during long outdoor sessions — even when I forgot to power it on. The 32 MOA circle reticle helps in fast target acquisition, especially in close quarters.
Reddit Comments:
Users love its blend of Trijicon-like features at half the price. A common Reddit quote: “If you’re not going to war, get a 507C.”
Mounting:
Direct fit on RMR cut — no plate needed.
🥉 Leupold DeltaPoint Pro – Best for Competition & Precision
The Leupold DeltaPoint Pro stands out with its wide viewing window and fast target acquisition. Ideal for shooters who prioritize precision and competition-level performance.
Product Specs:
Pros:
Cons:
My Experience:
I mounted the DeltaPoint using a C&H Precision adapter plate. The large lens area made fast target transitions incredibly easy, particularly in USPSA-style runs. The build quality and clarity justify the price tag.
Forum Insights:
Competitive shooters on Brian Enos’ forums frequently highlight the DeltaPoint as a top-tier sight for race guns.
Mounting:
Requires an RMR-to-DPP adapter.
💸 Swampfox Liberty II – Best Budget Option
The Liberty II delivers robust construction and clear optics for under $300, a budget-friendly yet dependable option for new Platypus owners.
Product Specs:
Pros:
Cons:
My Experience:
It zeroed easily at 25 yards, held through 500 rounds, and didn’t show point-of-impact drift. For casual or defensive use, it’s an unbeatable value.
User Reviews:
Swampfox optics get high marks across Reddit for customer support and clarity at their price point.
Mounting:
Direct RMR fit.
⚙️ Steiner MPS – Best Enclosed Emitter
Built for duty-grade environments, the Steiner MPS (Micro Pistol Sight) offers an enclosed emitter design that prevents dirt, debris, and moisture from affecting performance.
Product Specs:
Pros:
Cons:
My Experience:
I used the MPS during a two-day defensive pistol course. Despite rain, mud, and multiple holster draws, it maintained a perfect zero. For law enforcement or duty use, it’s nearly flawless.
Community Feedback:
On pistol-forum.com, many users praise its durability, comparing it favorably to the Aimpoint ACRO but at a better price.
Mounting:
Uses an RMR plate or direct mount (depending on slide cut).
