At the time of the original post 10-03-09, I was unable to find a 3913 TSW except for a battered, beat, overpriced one on GB.
However a forum member found me a new 3913 LS. I am very happy with it; it’s a great concealable pistol. I think now better for me than a 3916 TSW, especially if you were to actually use the rail on the TSW.
I have a 4566 TSW and have put a Laser on that.
