Holosun HS507C-X3-RD 1x 0.91x0.67 in Reflex Red Dot Sight, Color: Black, Battery Type: CR1632, Lithium Metal
w/ Free S&H — 3 models
A Holosun EPS Carry with solar and a green dot would be my choice for sure. I like the solar capabilities and I use it on my Shadow Systems 920CR. Get the C&H adapter plate for the EPS to mount it to your Hellcat. You'll barely be able to see the factory iron sights, so you may want to get higher ones.

This is my firsr, and I susp...

Product Info for Holosun HS507C-X3-RD 1x 0.91x0.67 in Reflex Red Dot Sight
The Holosun HS507C-X3-RD introduces a refined evolution of the classic 507C platform, combining a reinforced housing, updated branding, and advanced brightness management in a compact optic built for modern pistol setups. Designed around the popular RMR footprint, the X3 series delivers a low-profile solution optimized for everyday carry, duty use, and consistent range performance.
At the center of the HS507C-X3-RD-MRS is Holosuns Multi-Reticle System, giving shooters the flexibility to run a precise 2 MOA dot, a 32 MOA circle, or a combined reticle to match speed or precision needs. A forward-facing photodiode works with Solar Failsafe to automatically adjust brightness as lighting conditions change, while manual brightness control with memory and lockout modes provides full control when needed.
Powered by a CR1632 battery with up to 100,000 hours of runtime on setting six, the HS507C-X3-RD-MRS is engineered for long-term reliability. With Shake Awake technology and a rugged 7075-T6 aluminum housing rated IP67, it delivers dependable performance without added bulk or complexity.
For shooters who want a modern pistol optic that blends versatility, durability, and smart power management, the HS507C-X3-RD-MRS sets a new standard in performance optics.
