Ok just bought a Sig M18 and a Romeo 1 (not the pro) red dot and just like a kid doped up on sugar Christmas morning I start putting the two of them together..... then the wheels fall off!

Disassembly went fairly uneventful then the red dot on the slide, finger tighten as we go. One screw snug not torque yet, then the other bolt....stripped!!! Finger tight and striped! Looked a little closer and found out the screws are the wrong size. The sight is shipped with the good old size 6x40 screws which we all know is most gun red dots size thread pitch( I don’t know if they are just being dramatic) but no sig in there wisdom and wanting to be special went with a m4x7 thread pitch on the m17 and m18.....so I know what everyone is saying “just by 2 bolts and us them” but no it gets better. The bolts required are larger and the sight will have to modified, not only drilling the hole larger but the head is also bigger so it would also have to be modified.


Why Sig why...if Sig was a car it would have to be a Dodge, no aftermarket support and sorry customer service. Glock on the other hand is like Chevy, cheap parts, options, and interchangeable...so after some reading only a Sig Romeo PRO1 and a Trijicon will work. Only couple hundred dollars more....I mean it’s just money right?

One on the right is the right screw and the one on the left came with the sight16EDE5D2-DE3A-4347-B10A-AA1D63D8A26F.png

I relate with your plight, and that SUCKS!
Im digging to see if I have some extras now, for some reason I thought I did.
If not here a link at least.

Edit: After doing some digging unfortunately no luck…

Can you try using Torx screws instead of the Allen head? That's what I did to mount the Riton MPRD2 to my Beretta Apx carry.

No I found the screws I need, they won’t work with the sight. I don’t want to modify the sight because if need to warranty it out or resale it.
 
I bought this pistol to expand my horizons to other platforms, but the sour taste of the engineering at sig is so bad...I’m sure it’s a fine pistol seems to be built well and I haven’t even shot the pistol yet and I don’t want to. Why no warning about what will work or what you need.....noooo you have to pour over the web and read other people’s views or opinions, shift though truth or lies or misinformation. Just not cool sig.
 
So, as it sound like you’ve found out, that optic doesn’t work on a M18 it’s cut for the DPP footprint. Which is what the Romeo 1 pro is as well.
From what I have read the pro 1 has the screws that work, where as the regular Romeo has smaller screws, same foot print.
 
M17/18 flavor is MILSPEC - for some a big marketing plus but explains why you get a manual safety and metric screw threads . . .

Might not be all Sig decision making. But frustrating nonetheless . . .
 
You're better off with the pro anyway. I had a Romeo1 and wasn't terribly impressed.
 
This is one of the MANY reasons why I refuse to buy anything from Sig Sauer. Just one major example, I had a MPX with a faulty handguard with a bad heat treatment. The handguard bent and cracked from just a routine install of a plastic MLOK section and a Inforce WML. Something I put on my ARs, AKs and such all of the time. I wrote Sig to see if they could send me a replacement handguard and told them what had happened and that this should not have happened. 4 weeks, back to back emails and $750 later out of my pocket, I got a replacement handguard and then proceeded to sell all of my Sigs. I cant trust a company who wont stand behind their products and help the normal guy out. This and a cracked frame on a Sig ultra compact 1911, stripped screws on a p365XL factory plate.... I can keep going. Done with Sig. If I am buying a gun and 3 months later they release gen 2, then a gen 3 a few months after that and nothing is compatible with previous generations, what does that say about Sig.

given my experiences with Sig firearms over past decade, this is pretty low on the spectrum of their F-ups. Im glad people still purchase modern Sig pistols cuz I sure don’t!

Sig basically abandoned the Romeo1 cut and the Romeo1 optic after pumping the market full with as many early “RX” models as they could market.

It was a fragile optic that had no compatibility with any of the four common screw-mount footprints (RMR/DPP/Docter/Shield).

If you’re not expecting Sig to have incompatible generations of optics and slides floating around AND you’re not fortunate enough to spend money with places/people that know the difference, you can end up having a frustrating time.

Sorry to hear you got put out by the confusion
 
SUCCESS!!!!!!

Ok it’s not 100% done (have to file down mounting screws to get it flush) but it’s on there, found a optic plates adapter of all places amazon that works... so we’ll see.
 
One of the nice things about Sig optics is they integrate rear sight notches. You could probably match that optic/plate combo with a Dawson suppressor height front to have a usable backup picture.
