9 mm gun, what to get?

For a person starting out I would get a Ruger 22. cal pistol with the 1911 frame or a 22 cal 1911 copy. Learn to shoot and hit before buying a big bore pistol. After your competent with the pistol from safety to hitting the target go up in caliper. The 1911 type pistol can grow with you. 22. to 9mm., to 45acp. and back again.
