Notes
The Delta M is the compact-frame member of the AREX Rex Delta Gen 2 family, sitting alongside the full-size Delta and the optics/competition-oriented Delta X. Sources vary slightly on unloaded weight (roughly 19-22 oz) and grip height.
Background
AREX built its reputation supplying the metal-framed Rex Zero 1 to Slovenian police before pivoting to the polymer striker-fired Delta line to compete directly with the Glock 19 in the concealed-carry market.
