I am looking for a .22 lr semi auto pistol to introduce my son to pistol shooting. At our local range they have IPSC type competitions/get togethers and want my son to start playing. He is 12 and shot mostly rifles in the past. I am thinking of a 1911 with a .22 conversion so he could "grow" into it. Or something like the Ruger 22/45 that has same basic frame as 1911 then letting him switch when he feels comfortable. Any input on what you all think I should get?
