I was shooting .22 pistols with my sons (15 and 11) I have an ruger singlesix with a 4 5/8" barrel which is a great gun. but trying to keep it loaded as fast as those two gunslingers can shoot was a challenge so I am thinking I need another .22 revolver. So should I get anouther singlesix? I am thinking the one with a 9 1/2" barrel. any other ideas? JB
