With nearly 2 million copies in circulation worldwide, the Blue Book of Gun Values one of the most relied-upon resources in the firearms industry; has announced the release of its 41st Edition, dedicated in memoriam to the late publisher Steven Peter “S.P.” Fjestad. Spanning over 2,500 pages, the 41st Edition contains upwards of 1,700 trademarks with brief histories, approximately 23,000 descriptions of firearm models from across the globe including the new makes and models for 2020 and 500,000-plus up-to-date values for modern firearms and major trademark antiques. Additionally, the latest edition’s expanded serialization charts allow more years of manufacture to be determined on individual firearm makes and models. A feature of the book that collectors in particular will find helpful is its 80-page Photo Percentage Grading System (PPGS) to assist in determining the condition of a firearm, with guidelines available for pistols, revolvers, rifles and shotguns.
