I have been running the P211 with the Romeo X Pro. Every 100 rounds or so the window on the optic gets dirty and I have to wipe it off. I am thinking of switching to either the Vortex Defender XL or the Holosun 507 Comp. Anyone have this same issue with either of these optics? Or known of another optic that doesn’t have this issue?

I have a Defender Enclosed ST. It will get some oil and carbon on the lens when I'm shooting. It's my competition gun, so I'll wipe it between stages.

From what I have been hearing, this is a known issue with the way optics sit on the 211 and oil/crud
I don’t like making plans for the day. Because then the word "premeditated" gets thrown around in the courtroom.

I have the same issue on my 365 Fuse and Vortex Defender CCW enclosed.

I don't think changing the optics will help anything.  The same crap will still spray out of the ejection port.

OTOH, my P226 X5 Legion with RMR HD, which you would expect to get dirty being right behind the port, stays clean as a whistle over hundreds of rounds.  Go figure.

I used to let it bother me then just started ignoring it.  It was pretty gunked up last night in competition and I didn't even notice it.

Pistol optics usually get dirty. Just how it is.
