Ok, pet peeve here.
I really like the Swampfox Liberty and Justice. They're excellent sights with great features and value. But...
It just bugs me that they're slightly wider than the Glock slide. I'm sure they made them to be compatible with "most" mounts, but dang. This is the main reason why I lean towards a Holosun instead when I can get them on sale.
Curious to know if the Sentinel has the same issue on a SC slide.
I don’t believe so, as far as I know most if not all red dots that use a rmsc (sub compact) footprint such as the Sentinel should have no overhang. I will say though on a G26 slide depending on the serrations the Liberty is closer than most RMR footprint red dots to flush on the sides.
