Congrats!
I just picked one up blued 5.5" used on Wednesday. In MI, you can get a purchase permit, but then gun, then get the saftey inspection to make everything legal all in one day. That's just what I did. Luckily, the gun shop and the sheriff's office are only 15m apart! I had time to put a few cylinders through it before it got dark. This was all in one afternoon.
Tomorrow I plan on really giving it a workout. My main goal is to bet to be a better pistol shot so that I can improve with my 6.5" Blackhawk in .41 Mag but it might see duty on woodchucks and squirrels if I can get good enough with it.
