Read 2026-09-22. The page lists P250, P320, P320 Compact, VTAC, X-Full, M17, M18, X5, and Legion, for 9mm, .40, and .357 SIG grip modules. P250 and VTAC have no cards. X5/Legion is the X-Five Legion card. It will not fit AXG grips, sub-compact grips, .45 ACP, or X-10, so AXG Legion, AXG Equinox, and the XTEN cards stay off. X-Compact, X-Carry, X-Carry Legion, Spectre Comp, and FLUX are not in the list. Wilson Combat grip modules are not pistols. Re-use the factory wedge and spring. About 3 mm longer than stock.
