So I bought a Sig 365 and absolutely love it then I start seeing the 365XL with the Romeo optic and got me thinking of getting one but I don't know much about these new optics. I know you have to remove the Romeo to change batteries and you have to hit a switch to turn it on. I've heard about other optics that turn on when you draw and some seem to have a better sight picture but I just need some schooling. I don't really care about it as a concealed carry weapon, I have several but if it works better than irons why not?

While not on the P365 I own, I have several RMR sights. I like them primarily because of my age-related vision issues. At the range I use those shooting glasses with the bi-focal insert at the top of the lens so the front sight isn't blurry.

I just put a Trijicon on a HK VP9 that has the "shake awake" feature and so far I can't conceive of a down-side to it. The brightness of the dot adjusts automatically for ambient light and it co-witnesses with the suppressor height fixed sights.

On other pistols I have Vortex and a C-More. I really like the Vortex Venom but the VP9 I bought already had the plate that would fit either the Trijicon or a Holosun. Since the Trijicon is still made in the USA, it was my choice.

With a properly fitted IWB holster I don't find it harder to carry. Your mileage might vary.
 
Depends upon your use, but since you ruled out concealment*.........

Over 20 yards or so, the optical sight is much better than irons. However, you have to watch the size of the optic in comparison to your slide. Too big, it becomes clumsy.

There is a definite learning curve on using the optical sight. Especially if you have a lot of time with iron sights and a flash sight picture for the up close stuff.

The G forces on a slide mounted optic are in the neighborhood of 700+ Gs. Don't go cheap.

*The optic ads considerable bulk in most cases right on the top of the slide. This can make concealment very tricky.

I had a Romeo Zero on my Glock 43x for a bit. I ended up taking it off and selling it.

The Romeo Zero does have the feature that it turns on with any movement but just wasn't for me.

And that's not a knock on the Romeo, I'm just not a red dot fan.
 
I have a couple of expensive red dots and they work fine. The Leupold Delta Point Pro is excellent. Thought I would try out something less expensive so I got a Bushnell RXS-100. It's new and highly touted. It lasted 9 rounds on a 9mm before the light emitter came loose. Bushnell replaced it though they were very slow. That one lasted 6 rounds before the glass broke. Not gonna bother to replace it as I would never trust it. Lesson learned - again. Cheap junk. You get what you pay for with these things.
 
Have a look at the Holosun line, for small guns the 507K is great, especially with my old eyes. Had to have the slide cut for my Glock 43x, but it works great. Auto turn on, plain 2 moa dot, dot with 32 moa circle, or 32 circle only.

I own two semi-auto handguns with slide mounted red dots - A .45acp 1911 with a Burris Fastfire ll, and another .45acp 1911 with a Vortex Venom. Both have had a fair number of rounds thru them without issue. Both sights require you push a button to turn on (something I don't find an issue, especially for non dedicated self defense guns) Only real issue is the Fastfire requires removing the sight to change the battery. The current lll version does not. I would rate both the Burris and the Vortex as about equell for clarity, adjustment, and control manipulation. I think both are good buys for under $250.00

Personally I really like the "shake awake" feature on red dots. Especially if you are going to carry with it. The Romeo Zero has it, and is not bad at all for that price point. I also have a Vortex Venom, which doesn't have the shake awake, But again is pretty decent for the money. One thing to consider is I wear glasses, and some red dots will starburst with people with certain eye conditions ( astigmatism).
 
I have been carrying a RDS on my duty handgun for about 6 years. My main reason was aging eyesight especially in less then optimum light conditions. There is a learning curve, as with any new equipment, but once mastered the RDS is a great tool. I currently would only recommend the Trijicon RMR or the Holosun 507 and 508 for serious use. You might want to check out Sage Dynamics for reviews of RDS's. His testing protocols are brutal and his White Paper is considered the go to document for RDS use by LE. I currently carry the Holosun 508 on my duty gun. It has a larger window then the RMR, a titanium body for durability and a side mounted battery compartment so you do not have to remove the sight to change the battery.
 
Lots of red dots out there. I like the Vortex. Have a great warranty and hold up to the slide pounding.
 
Late to the thread, but I'll echo what SRG posted. Holosuns are a great optic at a reasonable price. I have four of them on various guns, a couple with round counts in the 1000s. I have a 508T V2 on my duty gun and that is the sight I'd recommend for a full size gun.

I'm only about two weeks and a couple hundred rounds into the 507K on my P365XL, but I have no reason to doubt it will let me down.

The Holosun only ended up being ~ $100 more than the Romeo version of the P365, but IMHO it's a much more robust sight.

Slide mounted RDS are a revelation, if you understand how to use them properly and train. Especially if your eyes are 'older'...
 
Another DeltaPoint Pro owner here, nothing but good service in thousands of rounds by now. I do wonder if a shake-awake setup would be a good choice for a truck gun, drive it around it would spend a lot of time awake and then when you need it the batteries might be... er... shot.
I guess it's a bit of a concern for a carry gun as well so I'd be careful to keep a fresh battery in it.
Carry optics are pretty amazing these days and I expect them to get a bit smaller yet. No question it's the way to go for bedside service and I'd consider it pretty much a must-have for a duty weapon these days.
It makes CCW a lot harder and could complicate presentation so I'm still on the fence regarding that use.
 
FWIW, the battery in my Holosun went 13 months of duty use without ever being turned off, though I'm sure it was 'sleeping' at times in the safe or nightstand. I'm just planning a 1 year replacement cycle, same as I do with my Aimpoints on the rifles.

Can't comment on the DeltaPoint, however, having not used one.
