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 sight
