With the TRS25, there's a VERY narrow window between being too loose and too tight. I have my TRS25 securely mounted using blue Loctite, which pretty much saves the day. I was just wondering about the Romeo 5 in this regard.
One BIG positive the Romeo has is the little 2 MOA dot; most red dots in this price range have 4s or 5s. The TRS25 has a 3 MOA.

I have not had any of the three SIG Romeo 5 red dots loosen up on my Picatinny rails during live fire. I have used them on Ruger 10/22 rimfire rifles, Three different semi-auto ARs chambered in 5.56 NATO, and on an AKM chambered in 7.62x39.
I have used one for a couple of carbine courses during which several hundred rounds of 5.56 were shot per day without it loosening up. That is not to say it couldn't happen.
I also have a Bushnell TRS25. It advertises itself as a 3 MOA dot reticle but I would call it a 3+ MOA dot at best. At higher illumination required during bright daylight, it blooms up closer to 4 MOA. The SIG Romeo 5 is much better in that regard IMO.
