No not the Doc, but a tool close to his heart...er belt...er whereever he hides the two to three he carries.
I saw it in my local gunstore/shooting range the other day and just had to have it. I didn't realize Ruger made a double action only SP101. I thought it was an aftermarket modification.
Now, should I have my Glock 30 backup my SP101 or the other way around?
