I was looking at the Sig cal exchange kit vice having my slide milled and was wondering if they mounted the same way or used different holes?

Thanks
Ed

I believe each optic has a proprietary mount or milling requirement for
the slide.

Thanks, I think that answers my question.

and as a practical matter all manner of people do the milling for an RMR, not so much the sig. And in any case the SIG is not very good, so don't do it...

The romeo1 is not very good? Can you tell us about your personal experiences with the RX line?

I have 3 RX's two 226's and one 320 and they have been flawless over the past 2 years of ownership. I also have a milled glock 19 with a RMR (RM06) and I have had nothing but flicker issues to the point I had to buy an anti flicker plate to make it work constantly. The Romeo1's have worked right out of the box as advertised.

So OP, if you are looking for the best bang for your buck it is hard to find a better deal than a RX X-change kit.
