Requires a THREADED BARREL in 1/2-28 or 13.5x1 LH. Most of these pistols do not ship with one — check your barrel before buying. Variant line (read 2026-09-22): "P320/M17/M18/X5" and "P226/228/229/P225/P6", each offered in 1/2x28 RH and 13.5x1 LH. The P320 token in that group is the full-size card. M17 and M18 are both the service cards and the commercial P320-M17 / P320-M18 cards. X5 is the X-Five Legion card. P226 and P229 are the unmarked cards, not Legion or Elite. P228, P225, and P6 have no cards. Compact, X-Carry, XTEN, and AXG are not in the variant line.
