Here is my little 759. I suppose the 9, instead of 7, is because of the
"dog ear" aka hammer protector? Next photo is 759 side by side with
a 459. Both with the "dog ears".
Charlie, That is an excellent find! Now, with the retention strap over the trigger guard, it looks as though you will be needing an early Chief's Special Hammerless to fill it up properly
My two Heiser 757s. For 2" & 4" K-frames. Bought the 2" M&P with that Heiser. Gun shipped in 1947 and appears to have been paired with the holster it's whole life.
