The Glock MOS and Springfield OSP platforms are two of the most popular optic-ready pistol configurations available - and getting the Trijicon SRO properly mounted on either one requires the correct mounting hardware designed specifically for those slide cuts. The Trijicon SRO Mounting Kit AC32085 is exactly that - the purpose-built kit required to mount the SRO to a Glock MOS or Springfield OSP pistol correctly, securely, and without any improvised solutions or adapter complications. The SRO footprint and the MOS or OSP slide cuts have specific dimensional relationships that require matched hardware to achieve a proper, secure fit. Using incorrect mounting hardware — or trying to adapt plates designed for other optics — introduces problems that show up under recoil. Loose fits, inconsistent zero, and optics that shift during hard use are all symptoms of mounting hardware that was not designed for the specific optic and slide combination it is installed on. The AC32085 eliminates those problems by providing hardware designed specifically for the Trijicon SRO on these two platforms. This mounting kit is not an optional upgrade - it is required hardware for mounting the SRO to a Glock MOS or Springfield OSP pistol. The kit provides the correct screws, adapter plate, and hardware needed to achieve a proper installation that seats the SRO correctly in the slide cut and holds it securely through the recoil of regular training and defensive use. The red dot mount installation hardware ensures the optic is at the correct height and aligned for a natural sight picture that works with the pistol's existing iron-sight configuration. The AC32085 includes everything needed for a proper SRO installation on either compatible platform, without the need to source additional hardware.
