Here is an odd one. A buddy bought it for his K-22 and told me it wouldn't fit. It is marked on the back JERRY BERMAN AND SONS SPORTING GOODS SAN BERNARDINO, CALIF. and K 22.
I took one look at it and knew it wasn't for a revolver. Berman and Sons were/are rack jobbers and distributors, not sure who actually made the holster for them. I bought it from my friend as it looked like it just may fit my AMT AutoMag II. Yep, fits perfectly. I'm sure it pre-dates the AutoMag by a couple of decades but I can't complain.
