I just purchased a new Colt Cobra and noticed the barrel is black. Is it an inserted barrel? It feels heavier than my DS also.
Have you checked the timing? I discovered that mine is way off. The bolt drops well before it's anywhere near the approach cut-out to the bolt notch. Colt is supposed to be sending me a shipping label to return the gun for repair.I took the new Colt Cobra out to the range after work. I was pleasantly surprised how good the trigger was. The front sight helps to get on target fast. The double action is very smooth. My Colt Detective Special was also taken out to the range also and I shot more accurate with the Cobra. The rubber grip, standard with the Cobra was more comfortable to fire also. Shot a 50 round box and I plan to shoot more often with it.
The gun will shoot out of time, but the bolt will eventually create a drag line across the cylinder.I fired a box of shells through it and no problem. As I stated I shot it more accurately than my Detective Special. The trigger is smoother and maybe since it is a little bit heavier, I am better with it.
