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?
