Just what you need - SIG SAUER Romeo1 Shroud Kit, Fits Romeo1 and Romeo1 Pro

The Romeo1 Pro when purchased separately includes this protective shroud, but when included as part of a gun package like the P226 SAO Legion RXP,the steel shroud is absent.

What I like about this besides the extra protection it provides the red dot unit, is how the brightness buttons are effectively indented. So when racking the slide, it keeps those buttons from inadvertently being depressed and changing the brightness level of the red dot.

There is one downside compared to the shroud that comes with the separately purchased Romeo1 Pro. It doesn't include the plastic cover to protect the unit. Moreover, that part is, as of this writing, not even available separately from Sig Sauer. It's a major oversight; I'd really prefer to be able to fully protect my red dot window when I tuck my firearm in my range bag.
