I am not sure that this question belongs in this venue but I can't think of an alternate spot so here goes. I want to set up a short range (15 feet) indoor range in my den where I can practice pistol shooting. I am undecided on if I should get an Airsoft or pellet or BB gun for this purpose. My focus is to practice sight alignment without consideration for trigger pull. I would appreciate any recommendations relative to the pro / con of Airsoft - BB - pellet for the intended use.
