I recently purchased a RWS Diana Lp8 Magnum pistol. I like it and it’s been fun to shoot. While putting a few pellets through it the other day, a mistake was made and the gun was dry fired. It only happened the one time, this I am sure of. This is my first air pistol and I know these are never supposed to be dry fired, my question is how concerned should I be about damage to this pistol? Is there any specific equipment I should own to better maintain this pistol? Where is the best place to find parts if needed?
