This weapon has premium assisted opening action utilized by Mods. 802, 803, 873.... Only permium components and materials were used in it's construction. It's made of Bellota steel with chrome-plated parts to reduce wear and oxidation. This is not "dime a dozen" Spanish SLE. It's well worth owning if it fits and the price is right (remember about current sloooow economy discount). The gun is fit for duke of Spain or any other Euro country.
