I train frequently with a air pistol. It is a enormously beneficial way to train. When the ammo shortage was going on, I trained almost daily with a air pistol, and when I returned to the powder burner range, is was obvious that the training paid off. I also tain with 22.cal. For fast quick shooting with a small pistol, I use a Phoenix HPA. (actually I own two of these). I own quite a few air pistols, and one in particular is a replica 1911 with blowback (recoil). He has about a 3oz trigger. A tin of 500 pellets is one cheap way to have fun shooting and training at the same time. I also have a Makarov BB gun that is about the same size as my LC9S. Get to the point where you can hit tin cans thrown in the air, and you will see your point and shoot skills really developing. I have some magnum spring loaded Pellet guns that do have a lot of recoil. Shooting long range with these is also a fun way to develop trigger and breathing control. The Bersa 22.cal and the Ruger SR22 are ideal for powder burner training.
