Hey there, I just picked up a Colt Frontier Scout and had a few questions regarding it. I have done some research and it seems to have been made in '62, and judging by the serial, late in the year, or at least toward the end of the production run. I have also found that some of the "F", mine is also an "F" models seem to have come with both 22LR and 22Mag cylinders. My main question is, it is stamped with .22LR on the barrel, but there are no markings on the cylinder, is it possible that this is one that came with both cylinders, or be possible to put a 22 Mag cylinder on? Thanks in advance for any and all help on this issue.
