Not to hijack the thread, but the buddy I mentioned that bought the TK2000 just traded (a Savage bolt action 20ga) for a Remington 870 SuperMag 3½" 12ga and some of the new Kent 3½" shells with 2¼ oz of diamond shaped shot.
At 50 yards the pattern was super-tight & dense, and the recoil was harsh but bearable. Actually much more comfortable then the Knight as far as recoil is concerned, but still not my idea of a fun gun to shoot.
