After running dots on pistols for a few years now I’ve pretty much adopted them across all platforms. Primarily RMR’s but after shooting my Sig M18 with a DPP quite a bit I’ve found I really like the larger window.

So long story long, I picked up a GGP slide for one of my G19’s that’s direct milled for the DPP and also has a rear dovetail.

So my question is this:

The optic sits slightly higher than the RMR so standard suppressor sights won’t clear it.. Is anyone running a similar setup and know what height rear sight will give me the lowest possible co-witness?
