This might be self-evident to you, and if so, then just ignore the post. However, if you plan to do a fair amount of range shooting, let me suggest you also have a good .22 as well. Learning and maintaining proficiency with handguns means regular repetition, and 9 mm ammo can get expensive if you shoot frequently. In contrast, a .22 is far more economical, yet still gives you the practice when it comes to aim, holding the gun still, etc. When I go to the range I always shoot my 9 mm so that I remember the recoil feel, but do plenty of shooting with my .22 as well. It keeps it economical enough that I can go more frequently. Incidentally, I thought it was advantageous, while learning, to shoot a .40 S&W too. The added kick gave me a bigger challenge to control, and then the 9 mm seemed easy to handle, in contrast.
