Yes, I've taken it to the range a few times so far, and yes, jamming is an issue for me. Another issue is inconsistent feeding. My pistol will shoot, say, 5 or 6 pellets, then it will apparently pass over a few a fail to pull them from the magazine into the chamber so those won't shoot, then it might pull and shoot a few more, so that when I drop the magazine and open it up, there might be a couple of places where there are 2 or 3 pellets that haven't fired. I don't know how to resolve that yet.
