Will a sig romeo zero fit this slide? — 3 Answers

Nice looking slide but I cannot find any screws that will mount the romeo zero. I have contacted LFA twice. The first time they said they'd send out screws that would work but that never happened. The second time they said they never had a screw that would work. The issue isn't finding a standard screw thread that will fit in the slide, the problem is with the shoulder design in the romeo zero optic. The metric sig screws have a shoulder that fits neatly into the optic but I cannot find a US standard screw that will work. Basically I have a nice looking sig optic cut slide that I cannot mount a sig optic to. This is a huge oversight in my opinion and the LFA customer service is absolutely terrible.
