Deeton 451 , I was wrong I just checked my Detonics and it doesnt have any numbers on it except for the serial number C21001 nothing else. Just Detonics .45 on the side. The gun is stainless and has pachmier grips. I have had it in my safe for over 10years and I remember it shoots fine but I was issued a Sig. and just retired so I am pulling it out as my carry weapon. Is this a newer issue or one of the first. I bought the gun used and dont have any paperwork for it. It never been worker on and it looks mint. Do you or anyone elseknow anything about the gun?
