SIG-LOC widens past the Romeo-X, Taurus T.O.R.O. filled in, three pistols confirmed
168 → 178 pistols · 71 → 75 optics · 17 → 18 footprints · 35 → 44 systems
SIG-LOC is no longer Romeo-X only. SIG now sells SIG-LOC Optic Ready slides across the P365 line and SIG-LOC PRO slides for the P320 line — the dataset's “Romeo-X only” language was already out of date. The SIG-LOC system split into three (P320 M17/M18, P365, P320 SIG-LOC PRO), a new SIG-LOC PRO footprint was added, and two new optics landed with it: the ROMEO-X SIG-LOC Compact and ROMEO-X SIG-LOC Pro. All three systems keep their verify flag — SIG doesn't publish the pattern its recoil-lug pins actually recreate, and guessing it is exactly the failure this dataset exists to avoid.
Taurus T.O.R.O. filled in with four numbered plates plus two C&H Precision plates, replacing a generic aftermarket guess with named, sourced SKUs — RMR/RMRcc options for the 856 and Judge, Holosun K and EPS options for the G3/G3c. The GX4 TORO got its own system (RMSc/K direct, plus an RMRcc adapter) and stopped inheriting a GLOCK screw-thread note that never applied to it.
Three pistols left the generic-plate bucket with real, maker-published fitment and had their verify flag cleared: the Arex Delta Gen2, the Arex Zero 1 Tactical, and the Rost Martin RM1C, whose RMR plate ships in the box.
Two new systems for 2026's A-Cut spread: an Aimpoint ACRO cut on the M&P9 M2.0 Metal, and Springfield's own A-Cut across six models — which forced a rename, since the system this used to live on was called glock-acut and is no longer GLOCK-only.
Two new optics confirmed and added: the Holosun 507-Promax (RMR footprint) and the EPS-CORE (RMSc footprint — not the K footprint the rest of the EPS family uses, which is exactly the kind of same-family trap this page exists to catch).
The Rost Martin RM1S subcompact was added on generic-plate. Its cut isn't published anywhere yet, and it is deliberately not assumed to share the RM1C's system just because they share a maker.
The Ruger American Pistol Competition keeps its flag, now with a sourced negative worth knowing: standard Ruger American adapter plates are explicitly sold as “will not fit Competition.”
Reported but not added this round. A guessed footprint is worse than a missing model, so these waited for a better source than what turned up:
- Holosun AEMS-MACRO and AEMS-MICRO — a 509T-footprint claim and an RMSc-adapter claim, both reported, neither confirmed on Holosun's own spec pages.
- Three Olight models (Osight XR, SE, X) and C&H Precision's house-brand optic lineup — footprints inferred from an article title or an adapter-plate name, never stated outright.
