I recently e-mailed the Kahr company asking about the difference between their regular Kahr 9 and that of the E9? Unfortunately, they didn't elaborate satisfactorily. I think the best guy to ask questions about guns are the ordinary folks and shooters: The only big difference I noticed between the said pistols is that the E9 (E for economy) is cheaper because it is made of chrome moly...so, what is this chrome moly?
