rocky_taco, there are 2 manufacturer's I can think of. If you google up EABCO, you'll get to the E.Arthur Brown web site. I own 3 of his custom single shot's. 2 pistols, and one rifle. The other, is MOA Corp. I typed in MOA pistols, and got his web site. It's operated by Dick Mertz. Makes a fine single shot action. Both were extremely popular in IHMSA compitition years ago. Their both in business, as I just checked. gypsyman
