The current X5 will only accept a Romeo1. I know this because I put one together for my brother. Sig is going to an industry standard size on there pistols though. The new size is the Romeo1T which is described as the same pattern as the DeltaPoint Pro (much larger than the original romeo1 pattern on your X5). I have one on a G19.
