I have a Springfield Loaded model 1911....
My choice was between the RO and the Loaded.
Loved the single sided saftey on the RO & the absence of front cocking serrations.
But did not like the adjustable rear sight (as I was not purchasing for competition shooting).
In the end, I went with the Loaded because it had the fixed low profile combat rear sight.
But you will not go wrong with the RO - great shooter (as is mine).
I have had almost zero malfunctions and have over 3K rounds through mine.
But if funds allow, go with the TRP (is is a step above both of these).
