'Hardtail bridge' in terms of most PRS, I think you're referring to PRS 1 piece Stoptail.
PRS did sth. like what you said
around '95 - '98 with some of CU24 and CE 24. So what you're looking for is considered
rare by me.
And yes, the current offerrings are Holcomb model (both SE and core limited) and SE SVN. Both are equipped with
real hardtail - a string through-fixed bridge similar to normal trem but without moving mechanism inside body cavity. Also, keep in mind these guitars were born in 25.5 and 26.5 scale length.
The SE 277 baritone also has the same bridge as Holcomb, but being a baritone with wide fat SE neck, I guess it's not what you're looking for. Also many S2 models feature fixed bridges like Vela and Singlecut, but none of them comes with thin neck.
