    DIFFERENCES BETWEEN THE K-80 AND K-32
    by Mike Young

    There isn't a day that goes by that fellow shooters don't call and ask the question: "What is the difference between the K-80 and the K-32" In this column, I will try to explain, without getting to technical, the main differences.

    First, we must understand the relationship between the two models. The Krieghoff K-32 was a redesigned, improved version of the Remington M-32. It was manufactured by Krieghoff and imported into the United States by Hal du Pont. Hal established a network of dealers throughout the United States who sold the shotgun for over 20 years. In the early 1980s Krieghoff redesigned the K-32 and the K-80 was the result.

    One of the first design changes and improvements made by Krieghoff was the hardness of the receiver. The K-32 was machined from a solid piece of quality German steel, but never hardened. K-80s are hardened by a "case hardening" process that leaves a thin layer of hardened material around the entire receiver.

    The next design change was the outward appearance of the receiver and iron. The K-32s, with a few exceptions, had a blued finish. The K-80s standard finish is an electrolysis nickel finish.

    Other changes were also made to the appearance of the K-80: engraving patterns on the receiver, trigger guard reshaped (contoured and extended rearward to a radius point), and an enlarged top lever.

    Perhaps the biggest design change was the trigger. K-32 triggers were made with a very large sweep rearward and the trigger "shoe" was thin. The K-80 trigger shoe was designed with a curved radius, allowing the shooter;s trigger finger to fit comfortably on the trigger. The K-80 trigger shoe, once redesigned, permitted for trigger adjustment forward and rearward by 1/8" in each direction. Both the K-32 and K-80 have the ability to select which barrel, top or bottom, the shooter wishes to fire first. The barrel selector on the K-80 can be locked, the K-32 cannot.

    Additional internal design changes were made to the K-80 from the original K-32. The K-80 hammers have gone through various changes. The very first
    K-80s had "soft" hammers, and in an effort to perfect the hammers, Krieghoff experimented with approximately four different hammer designs. They have settled on the current hammers which will accept both pull hammer as well as double release triggers in every gun manufactured, Sear springs in the K-32 and older K-80s were of a "clothes pin" wire spring that would collapse when the trigger was pulled. Many shooters were reporting broken sears springs while "on the line". In order to alleviate the broken sear spring problems, Krieghoff redesigned the sear and sear spring system around Serial Number 21500. Coil springs are now utilized instead of the sear spring system, and have been much more reliable. K-32s as well as older K-80s, serial numbers prior to 21500, can be retrofit with the new sear spring system.

    Ejectors. K-32 were manufactured with the ejectors (ejects the spent shell) held in place on the barrel by a visible screw in the center of the ejector. The design of the K-80 ejector eliminated the small screw The K-80 ejector is held in place on the barrel by a ball bearing and spring underneath the ejector.

    Stocks. The most distinguishing differences between the K-32 and K-80 stocks are as follows: K-32 stocks were available in varying shades of red, unlike the K-80 stocks. K-32 stocks were available in two "styles"- trap and skeet - and did not have palm swells. K-80 stocks are available in many "styles"- Monte Carlo high/low, Monte Carlo with adjustable comb, sporting clays, and skeet. For the comfort of the shooter, both left and right side palm swells were added, and "thickness" was added to the comb.

    Barrels. K-32 barrels are available with two rib configurations: a low rib (skeet) and a high rib (Vandalia) (trap); both 8mm in width. K-80 barrels are available with three rib configurations (8mm, tapered flat, tapered step) and four lengths (28", 30", 32", 34"). Factory choke tubes are available in all barrels now, whereas choke tubes were not available in the K-32 barrels directly from the factory, but were installed later by Briley.

    In summary, the K-80 is a newer, redesigned version of the K-32, that over the years has evolved to accommodate the needs and demands of shooters for today's competitive clay target sports.

    The only problem I see in Mike's explanation is that I have seen many K80's with the screw in the ejectors and own a couple myself. There must have been quite an overlap in the change over.

    You're right about the screw in the earlier K-80's and unfortunately he gives the idea it was a weakness in the design but the reality is as K-80's became popular, shooter's who didn't know how to use a screw-driver started buying them and when they took the screw out of the ejector to clean behind it (I have no idea why when a little squirt with a spray nozzle gets under it) and when they tried to re-install the ejector they cross-threaded the little screw.

    I guess Krieghoff got tired of fixing them and just changed the design to accomodate the dumbing down of shooters.

    Mike's explanation is the best we've had, so far. However, he didn't mention the 12MM straight, untapered low rib available in the U.S. as the International Skeet Model with Tula choke and factory porting. He also didn't mention the European version of the 12MM straight, untapered low rib available in 28" and 30", normally in field chokes, but probably also available in skeet choke in the 28" version. I have not seen any evidence that the non-Tula 12MM barrels were ever catalogued in the U.S. If anyone can find such a catalog listing, I would be interested to see it.
