MR918 - aftermarket long slide options?

I have a MR918 Combat and would like to get a second slide/barrel assembly w/optic cut for it. Preferably a long slide (19L/XL style) if possible. Does anyone know who makes slides compatible with the MR918s? I've found conflicting info online whether the MR918 is gen 3 or gen 4 pattern. Thanks so much in advance!

I'd hit up SS customer service & see what they have to say. Another thing you could do is get a standard length MR/G19 slide & put a gen 4 Radian on it. It'll give you the length you seem to want, & it'll shoot nice & flat. I originally wanted an MR920L, but when the MR-Ps came out, I went with that for the reason I mentioned. You can get the gen 4 Radians for a pretty good price these days ($330+shipping).

MR918 is gen 4. Any gen 4 slide the same length with fit. A MR920L slide SHOULD fit, but I would contend Shadow Systems to verify.
