Background: I like red dots on competition and carry guns. I test back to back and for everything except pure point shooting, there is a distinct advantage for me to shoot with a red dot... even at 7 yards at a fast pace.

For example, with a P365XL I was able to score 147/150 on the December Challenge Federal Air Marshal handgun qualification test which is rapid fire on a small target at 7 yards from concealed draw and with transitions.

I could not do as well with iron sights.

At this point because of my USPSA Carry Optics practice, I have 20k+ rounds with RDS in the past 5 months and lots of dry fire hours on presentation and transitions.

I currently have a Shield RMSc on the P365XL and have been waiting on the cheaper Romeo Zero to come out.

I know both are not as robust as an RMR, but they both have integrated back up rear sights that co-witness with the factory front sight. They are likely “durable enough” for my use on a carry gun as long as the back up sights are usable.

@cowboy1964 and I have been waiting for our Optics Planet orders to get in from Sig. late December is the current guesstimate.

The Romeo Zero is an $180 optic and the Shield RMSc is a $400 optic that is sold out almost everywhere.

So today, I got in a transfer of another gun. A duplicate practice gun since I like my XL so much. A like new P365XL with another RMSc already mounted, for the price of $770. Basically I’m getting the optic for $200 which is a bargain since they’re not easily available.

When I went to the store, they happened to have a P365XL with a Romeo Zero already mounted that I was able to handle and compare!

So this is my initial impression of the RMSc vs. Romeo Zero on 365XLs.

RMSc:
Aluminum housing and aluminum back up sights.
Thinner lens frame.
Known to be damaged on drop tests.
Co-witness with front sight.
Bright auto adjust dot.
$380-400 street price.

Romeo Zero:
Polymer housing and polymer back up sights.
Thick lens frame.
Probably will also damage on drop tests.
Co-witness with front sight, but the bottom edge of the lens and frame cut the front iron dot in half.
Bright auto adjust dot.
$180-200 street price.

If price was the same, I very much prefer the RMSc. The Romeo Zero feels cheap and the thick polymer frame is a little distracting and it seems to reduce the window size on an already small optic. I also don’t like the idea of polymer sights on guns, but that’s a personal preference not a requirement.

Is it worth twice the price of the Romeo Zero? I’m not sure. But to me (and the guys at the shop) it was no contest in the head to head comparison the preference for the RMSc from a straight optic standpoint.

I’ll update the impressions when I get my Romeo Zeros in. But barring impressive drop and durability testing of the Zero, I don’t see that it will be going on to a primary carry gun of mine anytime soon.

I know a few folks that are waiting on the Romeo Zero. Sounds like it might not be worth the wait.
On a budget, I think it will be fine. But if cost wasn’t a barrier, I think I’d prefer the RMSc. For actual carry, I think I’d like the RMSc.

For a range gun, probably fine. But the thickness of the shroud was kind of distracting.

I did not know the XL was available with a thumb safety.

I like it!

Thanks for the input, -JCN-! Based on what I am reading, and what I know about the price compared to Tier 1 red dot sights, I view them both as hobby grade optics, and I wouldn't trust either on a carry gun that gets a fair amount of use and abuse, including being in a wet environment where it is likely that the gun (and optic) will get wet. I may try one for kicks, but I am waiting for Trijicon or Aimpoint to move into this market before getting serious about a carry optic for the P365 XL or a Hellcat.

It is... if you own a Dremel. :D
I notched the frame and added the safety kit to the FCU. It took maybe 5 min total to do both.

If I were LEO or military I would choose a G19.5 with RMR or a P229 (in 357 Sig) milled for an RMR.

But I am not LEO or military and I have a slightly different take on them.

1. My carry gun doesn’t get much use nor abuse. I have a duplicate practice gun that gets high round counts. But I carry AIWB and I’m not getting soaked or climbing through mud pits with it.

2. If the RMSc or R. Zero aren’t durable or break... then so what? I’m still left with an excellent set of iron back up sights so I’m not any worse off with a broken optic than I’d be with traditional night sights. In fact, a big advantage is that they co-witness the integrated rear with the OEM front.

3. I shoot so much better with a red dot that I’ll take a less durable one over not having one any day of the week.

The one exception to that is if the optics failed to hold zero. That would be a deal breaker. But since it’s a co-witness with the irons, it would be pretty apparent right away.

So in my opinion, I think the RMSc and probably the R. Zero are fine for carry if you carry like I do. My carry guns see waaaaay less use than my hobby guns.

I’m not interested in a large, heavy optic for my carry gun. I actually have an RMSc to RMR adapter plate, but the height of a cowitness front sight would be ridiculously tall.

But like I said, if I were military or LEO, it’d be something heavier duty for both gun and optic.
 
Nice write up, like you I am all in for red dots and also compete in CO's in USPSA, although moving to Open.:D . That said I am looking at both those for my 43x (have the XL too but prefer the 43x).

Any update since you received the romeo zero? Would be nice to save a few $100 but doesn't look like that will happen, leaning pretty hard to the RMSc. Was hoping I would see some new micro-dots at shot show but doesn't look that way.

I got a coupon for 20% off so I canceled my Romeo Zero order and reordered... haven’t received them yet. I wound up paying ~$180 for each of two so I’ll probably still keep the order.

I’m curious how the Holosun HS507K will stack up. Looks aluminum and will be priced between the two.
First I've heard of the Holosun 507k. This looks promising.

The 509T looks good too, for RMR or piccy type mountings. Aaron Cowan already got his hands on a preproduction unit and he likes it and seemed to do well in drop tests.

I really like Holosun, but I don’t find their auto-adjust to be as good as Trijicon and the shake awake is a little sluggish on the 507c. I also heard that maybe the 507k doesn’t have auto adjust? If that’s the case it’d likely be a deal breaker for me.

JCN, which dot gun did you have a higher USPSA classifier with?
I can never tell if you’re trying to be helpful or trying to be a smart Alec.

Giving you the benefit of the doubt, I have only used Leupold DPP 7.5 MOA triangles on classifiers. When I started with dots, I really preferred the larger dot to get it in the window faster.

But as my mechanical index has improved, now I am finding that the dot is too large for precision work and am working in the new Sig Romeo Max (Michel) 3. I think it’ll be a nice upgrade.

The benefit in improving my mechanical index is that I have no issue with a small dot like a RMSc.

On a self defense gun, I want absolute co-witness irons though.

My gaming requirements are different than my self defense requirements due to weight and bulk. There’s no doubt that I’m a much better shooter with my gaming gear than a micro compact. But I’m still “decent” with my carry gear and that’s why I like running the Federal Air Marshal qual to make sure it’s “good enough.”

They finally updated my Carry Optics classification, too! Cheers!

JCN, no I was serious. Only way I believe to verify which is better is to run gun to gun on a standard. I see you have already learned how to sand bag, nice job on A class! By the way, I think I see your problem... To many different platforms.. I haven't accepted a dot for carry yet because in the incidents that I have been involved in, it's point shooting.

I think that is valid for competition. But that’s not even remotely what we are talking about in this thread.

Carry guns and micro carry optics are pretty much synonymous with compromise. Either in form factor, durability, battery life, effectiveness of auto ... things that don’t come into play during controlled competition.

Judging a micro compact RDS based on competition criteria is like saying that a Honda Accord isn’t a good daily driver because there aren’t any in NASCAR.

My personal criteria for a gaming optic are different than my criteria in a carry optic.

Just like my personal criteria for a gaming gun are different than my criteria for a carry gun.

For people who understand this, here are my extra criteria for CCW optics (that I don’t care about in a competition optic):

  • Good battery life
  • Great auto-adjust for light
  • Able to stay on all the time or at least have a fast enough shake awake that there’s no lag
  • Accurate co-witness ability if integrated rear sight without having to go to a front sight so tall that snagging becomes a concern
  • Improves my shooting compared to iron sights in all measurable parameters
I don’t believe that a head to head performance on a gun is the parameter that I’m looking for in an optic unless there’s something so very different about one’s window, dot or some other esoteric parameter. Because all the micro dots are similar form factor and MOA.

I do compare different carry guns in a head to head, though. That’s how I wound up with the P365 XL over G43/43x and my previous Kimber Micro 9.

Like you, I currently still 99% carry iron sights.
 
It's about time this post is resurrected.
My daily carry in the last year has been a Sig P365XL with a Shield RMSc sight. Although I'm a competition shooter and get most of my trigger time with sexy raceguns (running a pair of Shadow 2s with slide mounted red dots this year), this Sig combination surprises me each time how good it is when I take it to the range. Compared to compact and full size guns, the Sig is much more comfortable to carry concealed with a red dot, doesn't have a towering front sight to co-witness (holster selection++) and requires a bit more training to shoot well quickly. I find my support hand compressing my strong hand's fingers for want of grip space on the gun, but when you shoot with a red dot, calling your shots and getting feedback is easy and training is more effective. Also I run long distance with the gun in a SmartCarry, which provides comfort and makes me look unarmed. For carrying when not running I use a Comp-Tac MTAC IWB holster for the gun and a Snag-Mag holder in weak side front pocket with a 15 round reload.
I've heard reports about the plastic lens material of the RMSc scratching with almost any form of cleaning cloth, so I just haven't cleaned it except for blowing dust away until there's a chance to get a glass lens.
Before this gun, my favorite carry gun was an M&P 2.0 compact with an RMR on a dovetail plate, without a co-witnessing option but holster friendly (also the red dot is above the waistband, covered by upper garment rather than trousers, which to my mind is more comfortable than lower IWB with a red dot). For carryability + shootability + safety, the P365XL ties with this awesome gun. Am very happy.

Nikon lens pen is what I use to clean my RMSC. I use the brush to knock off any dust or other particulate matter and then B&L lens wipes or a spray bottle of alcohol and a microfiber eyeglass cloth to remove any film or smudges.

I have done this for the past few years and have had no issues.

Regards,
Happyguy :)
