WT-0005P-5 is designed to fit the Walther PPS and PPS M2.
The T-slot and dimensions of the PPS and PPQ are the same, but Walther uses different retaining methods. The factory PPQ sight has a windage screw for retention and adjustment ability. The XS F8 sight will fit in this channel, but is not adjustable. Instead, set screws and thread locker are used to retain the sight.
