All (or rather most) new Lycoming engines are shipped with Slick Mags. Lycoming switched from Bendix to Slick years ago.
Continental Engines (a Lycoming competitor) owns Bendix mags.
The Slick mags are lighter and less expensive.
Lycoming Service Instruction 1443M
lists the Slick Mag model numbers.
