Welcome to Sig Talk and Congrats on your P320RX. Yeah, you have the right idea - shouldn't need any co-witness with a properly zeroed reflex sight. Make sure your Romeo's POA and POI are sighted and you're good to go.

EDIT: I'll add my P229RX's Romeo was off quite a bit. Windage ~6" and elevation ~4" at 10yds...


Cheers

Yeah, agree that snugging-up that battery cover's gonna help. Another potential issue with these alloy threaded battery caps is oxidation. No expert here, but know some that are. Aluminum develops a very thin surface oxidation that you can't even see. Normally, alloy fasteners have enough length, thread locker or lube to at least mitigate this erosion. But Romeo's battery cap threads are so shallow and without thread locker or lube - This 'rust' may cause it to loosen over several months.

No worries, a quick cleaning of these threads when changing the battery is all that's necessary. Some light steel wool action or just use a pencil erasor should do the job...


Cheers
