A while back I picked up a Speed Six S/S with what I was told a 2 3/4" barrel. I was comparing the Speed Six with my GP100 3", checking out measurements and etc. When I measure the Speed Six barrel it reads 3", the same as the GP100. Am I doing something wrong or could this be a 3" barrel instead of 2 3/4"? Any help would be helpful. Thanks in advance.
