Disclaimer.... I don't claim to be a machinist nor did I stay in a Holiday Inn last night. Also, My tool is from Harbor Freight. However, here are my unscientific results... YMMV

Sig Romeo 5 SOR52001 = 1.107 ish



Sig Romeo 4B SGSOR41101 = 1.080 (Tried to get the measurement right behind the flip cap. Saw variations from 1.075 - 1.083 ish

Thanks a lot. Does the flip cap come off of that one? I didn't know it had one or I would've kept it off the list if its not removable.

I came with the flip cap installed, and yes, it is removable.

1.035” is what my Romeo 4c measured out.

Seems like 29mm is the max, maybe 29.5mm to be safe?

28.8mm/1.135" on my HE503GU-GR Elite at the front edge
