It's pretty close to a Kel Tec in size. If I got one, it'd be a pocket gun. I carry my P11 in a Blackhawk number 4 which also fits my little Taurus 85UL revolver and I carry a little, thin P64 Radom in it occasionally, though the Radom has some room to flop in that holster. Anyway, any soft pocket holster for a PF9 or perhaps P11 should fit the Ruger I'd think. I put my newly acquired Ruger SR22 in it and fit great!
It's only a tad longer at the slide than my P11 and almost, but not quite as wide.
Of course, if you're going to carry IWB and want a custom fit, you might have to wait, but most of the outfits should be making 'em now. I have a 140 dollar Mitch Rosen Workman tuckable I got originally for my P11, but I don't use it much anymore, just drop the thing in a pocket holster and go. It also fits in the holster section of the Bandera Leather belt I had made for my Ruger P90, as does my new SR22, which is cool. I bought the belt for my P90, but found the decocker dug in to my love handles rather irritatingly, so I don't carry the P90 in it often. In THAT case, though, belt tension retains the gun even though it's not as wide as the Ruger P90. Works great, though, no complaints, with a gun that's reasonably wide.
I can't carry anything like my Radom in it, too thin, lacks enough retention.
