SPF ...
Ray at LOBO Leathers made me this "Model 1 Pancake" for my S&W Model 19-3 with a 3" bbl, .357 .... but I sold the Revolver and never got to use the Holster.
Here is a link to the site
Lobo Gun Leather - Model 1 Pancake Style holster
Mine is like the 5th one down,, in kind of a natural brown color.
Asking $35 includes shipping
Even if you don't buy mine you may want to consider Rays other offerings ... he is a good guy, honest and reliable, and he makes a good quality product at a fair price.
