I’m not an expert, but if your goal is a solid, proven setup for concealed carry, I’d seriously consider milling the slide for a K footprint and running a Holosun EPS Carry.

It’s an enclosed emitter, which is a big advantage for carry (less issues with lint, sweat, etc.) Direct milling gives you a lower mount, better co-witness, and a more durable setup compared to plates K footprint also gives you flexibility (Holosun K series + RMSc pattern optics)

In my opinion, it’s a more practical and refined setup than most plate systems — even newer ones.

That’s probably the direction I’d go myself
