Kahr offers a line of "economy" pistols which are identical to the P series of pistols except that some luxury features are eliminated to cut costs. The polymer-frame CW economy models have fewer machining operations, pinned-in front sights rather than dovetail, traditional rifling rather than polygonal rifling, "rolled-on" lettering rather than engraved, and come with only one magazine. CW pistols generally retail for approximately 20–30% less than the full-featured P series. The E series is a discontinued line of Kahr economy pistols with stainless frame; the E series was discontinued in 2004.
