Whether you have the potential to shoot a pistol well depends on your hand-eye coordination, eyesight, and level of physical fitness, as well as willingness to concentrate and practice effectively. Guns that fit properly are always easier to shoot accurately than guns which do not. Consequently, fit determines which one is best for any particular individual. Any well-made 6" barrel will hold a 1/4" group at 25 metres. The best performer I have run across bar none is the Margolin MCM pistol. It is light enough to learn on. Many new shooters will find the High Standard and Ruger pistols too heavy to shoot well. You learn to shoot well faster on an MCM. They are very easy to strip for cleaning and assemble. They are less expensive (in fact severely underpriced) than any other gun in their class. They are capable of winning scores (if they fit your hand properly) out of the box in the hands of an accomplished shooter. With the light weight barrel the muzzle jumps higher on recoil, but it also returns faster than on guns with heavy barrels. They also will shoot almost any .22 lr ammo from standard velocity to high velocity.
