I shoot a lotta guns on the regular rotation (Hatsan 85, Webley VMX, two Crosman NPs, Diana 460 Magnum, plus a few pumpers) and every one of them has a different trigger feel, and most like a different hold/particular pellet. My first couple shots are usually off as part of the "relearning curve" of each trigger. Just about the only time I don't experience this phenom is when I shoot exclusively one gun for a few days straight, with all other guns staying on the rack, or if I pull out the Diana...that gun is stupid-easy to shoot, what a trigger! I'm not saying it can't be the gun or a mechanical whatsit, I just think it more likely to be the shooter (as it most definitely is in my case).
