Geoff, I did indeed get an HW97K, sometime after I bought my Lightning. As Leadbottom mentioned, the HW97K is the carbine (Karbine in Deustch) version of the HW97. The HW97K is the most common version you'll see in that rifle. I think the longer barrel HW97 is pretty hard to find this side of the pond these days. The HW77 uses the same action, basically as the HW97 and is available in the full length rifle more commonly. The HW77 does have a more European conventional stock profile on it. The HW97K has a stock more oriented to scope only use, with a much higher comb. The HW97 and TX200 are the most used springer rifles for FT competition an I fell it is really neck and neck between the two as to which is the better rifle. My HW97K is brilliantly accurate, very easy one hole groups at 10m, almost too easy. I have an Air Force 4-16 x 50 AO scope on my HW97K in a one piece, high mount. This is a somewhat heavy rifle, by design, as the added heft tend to stabilize the rifle in off hand shooting for FT, the TX 200 shares the same design philosophy. My HW97 certainly has the accuracy to be a fine hunting rifle, but I would probably only consider it for hunting from a fixed stand or hide, as it would be a bit more weight than I would want to tote around on a walking hunt all day.
