Good luck finding one. They tend to find permanent homes once they are bought up. At least mine has a permanent home. I just took it out last week to remember why I bought it. The 50 rounds I sent through it pushed the total to 1125 and I only shoot it a few times a year. I do hope you find one that someone can part with. They are great guns.
there is a blued 24/7 OSS at my LGS, I think the price is around $400 used. I can call tomorrow to confirm, you would have to have it sent to your FFL, as it is currently sitting in a display case in Yuma, AZ.
