After cruising through the Taurus, Ruger and Browning sites, I have a couple more questions. Taurus has quite a line-up of 17HMR. How would that be for a 1st revolver? Are the shells that much more expensive? Doesn't Ruger make one that comes with 2 cylinders...22 and 22Mag? Also, what about the Browning Buckmark? I know its not a revolver, but would that make a good 1st pistol? Thanks
