I like the all. I have 2 4 inch guns (one S&W Mod 67-1 in .38 Spcl., and a 4 inch Colt Python.), one 6 inch gun (S&W Mod 28-2 in .357 Mag.), and a 10 1/2 inch Colt Python. The last one has been fired less than 4 times since it was made. For my shooting it is too heavy in the front. All the others I love to shoot just the same.
Though my true preference is a 6.5 inch single action for revolvers. It has the right feel in my hand. Though it is a matter of preference on my part.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
