1. HOLOSUN 507K
The HOLOSUN 507K has become the gold standard for micro red dots on subcompact pistols. It’s an incredibly tough and advanced sight designed specifically for slimline carry guns, making it one of the best matches for the Taurus Millennium G2.
The 507K features HOLOSUN’s Multi-Reticle System, offering a 2 MOA dot and a 32 MOA circle for rapid acquisition. Built with a 7075-T6 aluminum housing and an IP67 waterproof rating, it’s ready for concealed carry or rugged field use.
Specs
My Experience
On my G2, the 507K delivered an immediate upgrade in precision. The glass clarity is outstanding, and the Shake Awake feature ensures it’s always ready when drawn. I found zero shift minimal after 500 rounds of 9mm, proving its ruggedness. The large window, despite the compact body, made quick follow-up shots natural.
Online Comments
Users rave about its battery longevity and durable build. Many say it’s the “perfect EDC optic” for smaller pistols like the Taurus G2, Glock 43X, and P365.

You’ll need an RMSc adapter plate or a custom-milled slide to mount it securely.
2. Crimson Trace CTS-1550
The Crimson Trace CTS-1550 is a budget-friendly, ultra-light reflex sight that pairs perfectly with compact pistols. It’s ideal for shooters seeking simplicity and reliability without breaking the bank.
It features a crisp 3.5 MOA red dot with automatic brightness adjustment and a lightweight polymer housing. This optic is designed for EDC users who value fast target transitions and no-fuss operation.
