Well, I’ve been enjoying mine until tonight:
One of the optic mount screws sheared off at roughly the 3,200 round mark. I believe this is a result of using a RMR-footprint optic and filler plate rather than a direct-mount DPP-footprint optic. I’ve ordered a Holosun SCS-320 optic (which utilizes a DPP footprint and is specifically designed for Sig’s R1P/R2/DPP slide cuts) to replace the 508T w/ filler plate setup. Hopefully that’ll be a stronger combination going forward.
The pistol itself has been flawless with absolutely zero malfunctions, and is currently 1,200 rounds into a 2,000 round “no cleaning/no lube” reliability test
