Matthew’s Patent Project 99 Build Kit by The Gatalog

$369.99

Everything needed to build a Walther P99 in .40

Frame design by Matt Larosiere of The Gatalog

The Gatalog is the first corporate successor of Deterrence Dispensed. Owned and directed by Matt Larosiere, The Gatalog formed in 2021 to promote commercial kit designs for builds like the FGC-9. Though its license standards are regrettably corporate and closed source, The Gatalog today promotes upmarket parts kits conversions and has built a reputation for above-average documentation.
