I finished up a couple of holsters for a customer. The short one is for a Ruger SP101 with a 3" barrel and the long one is for a Ruger Single Six with a 9 1/2" barrel.
I only had a Single Six with a 6 1/2" barrel available so I went out to my wood shop and made myself an extension with an old cleaning rod, piece of walnut and a bolt.
Here are some pictures. Comments welcome.
