Was searching the internet for information about these and found this site. I found one for sale. Mine differs from the one pictures here in that the one that I have has an 1 3/8" barrel out the front of the brass chamber insert. Don't think these are very common. This one was sitting in a box of loose ammo on a gun shops counter for about 10 years. Owner want $50.00 for it. Yesterday I looked at it and offered $20.00 for it, he countered at $25.00 and I said "no it has been here for 10 years", he relented and I got it for my price.
