I have a Detonics Combat Master I bought at the gun show in Denver around 15 years ago. It's stainless with Pachmayr grips, milled front sight, rear sight is adjustable only horizontally. The left side says DETONICS .45 - Combat Master. The right side says DETONICS .45 - SEATTLE, WA. - T40xxx or T4Cxxx. I've only shot 100 rounds out of it since I bought it and the only marks are a couple small scratchs where it fell on the floor once.
