Les Baer 1911 parts have a reputation for quality and durability that is nearly unmatched within the industry. Machined from bar stock to precise tolerances and heat treated for strength, this extractor will provide years of reliable service in your handgun. Notes:The difference between Series 70 and Series 80 extractors is a plunger retainer stud machined into the Series 80 extractor. This retainer stud holds the firing pin lock plunger in place on Series 80 slides. All extractors which are designed to work in a Series 80 1911 will also work in all Series 70 guns, however extractors designed for Series 70 guns lack the machined cut which allows the firing pin lock plunger to be installed and therefore can not be used in Series 80 guns.
