Upon further inspection Kernel, you are correct. DA/SA If it was done outside the factory, the work is incredible. It could explain what I see as a shoulder rig rub however. Thanks.
Well, I guess there is no need to bother Mr. Jinks on this 13-3 but I will use the form to letter this Lew Horton 24-3 unfired NOS that arrived in the mail today! Thanks for all your help gentleman. Very interesting discussion!
I bought a 3" Blue M13... then FBI issue & hard to come by... I loved the balance of the gun. My financee' declined to sell it back to me when we parted ways.
I consoled myself With a 3" M66 (-2) which I bought in 1986. It instantly became my favorite off-duty & trail gun. I hand made a (mostly) copy of a Bianchi 5BHL for it.
You can contact Lew Horton Dist directly to confirm if a gun is one of theirs.
