Hello, new to the forum. Have always been intrigued by the Combat Master but never thought I would get to own one. Work part time in a gun shop, boss comes out of office last Sat. and says " put this out. Hands me a black gun pouch that says Detonics .45 on it. I said, what can I buy it for? Got m price and bought it. Near mint, serial # 3986. Is this a good find? Anything special about it? Left side says Detonics Assocs, Seattle WA. Right side says Detonics .45. Mag says on bottom Detonics .45 Auto. Does not have MK 1 on it anywhere. Thanks for any info available.....
