The difference to me is my preference for a small red dot.

The Romeo 1 is a 3 MOA dot
Vortex Viper RD is a 6 MOA dot.

I don't have either yet but am putting a Romeo 1 on my X-Five when I can finally get one.

What Steve said
I think both companies are great, can't go wrong with either, just personal preference

I agree with Steve regarding size, smaller dot is better. This was driven in to me this past summer at an Appleseed event. First day, one of my 10 22's with a Burris FastFire III was in use. The dot was so big, it covered all the silouettes, I scored miserably. Next day, AR with Aimpoint T-1 was used, scores increased dramatically.

Some argue the larger dot is better for closer distances. That might be true. But why limit your range by choosing a bigger dot? I'd suggest you go smaller. As to which product? Whole nuther can o'worms.

Steve, I meant to say the Vortex VENOM which is available with a 3 MOA dot. I corrected my OP

Vortex Optics - Venom Red Dot 3 MOA Dot

The venom is a much higher profile, and won't cowitnees on most guns, even with Suppressor sights.

I tried a venom, and did not care for it. I liked the top loading battery, and the 3 moa.

FWIW, I've had a Trijicon RM08g, RM06,a vortex Venom, a Jpoint circle dot, and now the Romeo 1. I like the romeo 1 the best. The window size and shape works much better for me than any of the others. After having some larger MOA, I wouldn't want anything larger than a 3MOA, I like the top loading battery, and the adjustability (auto adjust doesn't work in all conditions) is very important. The RM06 would be second, and I have the Jpoint on my M&P Shield EDC where size is crucial.

Also the Venom is the only one that I had to shim in order to zero it. Shimming shouldn't be a deal breaker, but I thought it was worth mentioning.

safe to say i'll wait til the romeo 1 is available...


smh.

I definitely want a top loading battery which is why I'm looking at the Venom vs the Viper.

Initially, I plan on using it with my 22 Conversion for range use and replacing the rear sight, so co-witnessing isn't an issue.

Not sure about a RDS for EDC with my P320. Will have to see how I like it.

Keep in mind, most reflex sights today, have a fairly long battery life. Trijicon which many consider the bench mark are all bottom load battery. Don't get me wrong I prefer a top lad also, but It's not a deal breaker for me. I would put cowitnessing before top load battery for importance...especially if you're new to reflex sight on a pistol...cowitnessing should shrink the learning curve.

As far as reflex on EDC, the top of the slide is usually not a problem area for comfort or concealment for most people. Once you have your presentation down with a reflex sight, it's at least as fast as iron sights. And actually the presentation with the reflex sight that cowitnesses (and only a very slight change if it does not) is the same as the irons....the difference between the 2 as far as presentation, is all in the shooters mind.
