The Mark I Lightweight is a very rare variant of the Mark I made with a lightweight alloy frame originally intended for paratroop use. According to Massad Ayoob, these were introduced commercially in the 1950s but never caught on. The Lightweights are marked only with Fabrique Nationale's rollmarks, not Browning's.
