Bad results with SIG Romeo red dot on Shield Plus.

[Japle]

I bought this SIG Romeo Zero sight to use on my S&W Shield Plus.
The first one I received had a big scratch on the front lens. SIG replaced it with one that, no matter which way I turned the windage screw, the dot moved to the right.
The elevation on last one won't adjust enough to get on target. Cranked all the way, it still shoots 10" high at 50 feet.
I like the "shake-awake" feature, but unless I get into an "affair of honor" in a phone booth, the sight is pretty worthless.
S&W puts Crimson Trace sights on factory guns. Is that my only choice?

If you've thrown in the towel on the SIG Romeo, perhaps the Leupold Deltapoint Micro?

Leupold states that their M&P version does not fit the Shield CORE or EZ, but they don't rule out the Plus. Maybe it's a possibility?

I checked out the Leupold. Can't find any info on anyone mounting one on a Shield Plus and it looks too big to use on a sub-compact.

Had a P365 with a turnkey SIG slide that came with the Romeo 0. Not many kind words for it; the original couldn't be zeroed, and the replacement is a pain to turn off/on. I should have simply used the shake and wake.
Finally gave up, and went with a Holosun that fits the same mounting, and I like it much better.

I run the crimson trace micro on my P365. I have 2 Trijicons on a G40 and G41. I can say that the CT is tough as nails and never a problem. Getting ready to order another one.

Had a new Holosun for the P365, ended up giving it away. I gotta have the auto adjust. The shake awake is the icing on a very nice cake.

I went ahead and bough the CT sight that S&W puts on at the factory.
Got it directly from CT, so if there's a problem, I can deal with them direct.

I don’t have anything good to say about the Romero sights from sig.

My 365s have Holosun 507ks on them, without any issues.

The SIG Romeo Zero uses the "J-Point" footprint. Do some web searching, I had the same issue with a J-Point way back when they were the only thing that small and light, somebody makes a "wedge" adaptor that can be mounted "backwards or "forwards" to give a fixed vertical offset to adjustment range. Main down side is it adds ~3mm to the sight height.

Actually the Sig Romeo Zero uses the Shield RMSc footprint. The other Sig micro optics use the J-Point.

The J-point and Shield footprint are the same. See: https://www.americanrifleman.org/content/navigating-the-optics-ready-market/

The JP Enterprises JPoint is just one brand of optic that fits the Shield RMS/RMSc footprint according to this website

https://www.optics-trade.eu/blog/footprints-on-red-dot-sights/#Shield_RMS/SMS_mounting_standard

From that website is the list of optics that fits the Shield RMS/RMSc footprint.

Shield RMS/SMS mounting standard
Shield sights are incredibly compact, which is why Shield had to come up with a mounting standard of their own. It is designed similarly to the Noblex/Docter mounting standard (there are two holes for the screws and four sockets in which the notches on the mount/adapter fit, one in each corner). The sockets, however, are a little bit wider and closer one to another.

Red dot sights that share this mounting standard:

• ADE Advanced Optics RD3-018 Spike
• ADE Advanced Optics RD3-021 Nuwa
• JP Enterprises JPoint
• Leupold Delta Point Pro
• Shield RMS
• Shield RMSc
• Shield RMSw
• Shield SMS
• Shield SMSc
• Shield RMSx
• Shield SMS 2.0
• Sightmark Mini Shot A-Spec M3
• Sig Sauer Romeo Zero
• Swampfox Sentinel 1x16
• UTG OP3 Mini Micro
• Vector Optics FrenzyS 1x16x22
• Vector Optics Frenzy-S 1x17x24 MIC
