Wanted to order a Combat Master for my S&W new model 66 with a 2 3/4” barrel. Called customer support and was informed that the holster is made for the old model 66 with the 2 1/2” barrel, because there are a lot more of those out there. Was told I would have to order a custom made holster ( add $50 ) . Took a chance and ordered the regular holster. Couldn’t be more satisfied. Fits just fine. Thank you Galco. Delivered promptly, a beautiful holster.
