LPA SPS · 3-Point · Ruger Mark IV 22/45 Lite
SPS17SS30 is listed for Ruger Mark IV 22/45 Lite – not for SIG 1911 .22 The official LPA order table assigns SPS17SS30 to the Ruger Mark IV 22/45 Lite. The previous shop text for the SIG Sauer 1911 .22 was therefore factually incorrect.
The suffix 30 denotes the version with white dot markings. It changes the sight picture, not the mechanical mount.

Black-Raptor Buying Guide
This guide is aimed at owners of a matching Ruger Mark IV 22/45 Lite who want an adjustable mechanical sight with a classic three-point pattern. If you only read “Mark IV,” you should still check the specific 22/45 Lite version and the existing sight setup.


Fits well if … … you own a Ruger Mark IV 22/45 Lite with the matching original sight mount and prefer three white reference points.


Probably doesn’t fit if … … you want to equip a SIG 1911 .22, another Ruger version without confirmed mount, or a heavily modified sight.

30 Version White dot markings support quick orientation. They are neither fiber optic nor Luminova.
