I tend to judge my guns' performance based on my performance in pistol matches, like USPSA, IDPA, and steel.
The King Cobra is faster than the Python for me. I'll get better hits with the Python, because I will shoot it more accurately, but for pure speed, the better grip angle, shorter reach to the trigger, and shorter trigger travel of the KC makes a notable difference. The recovery for the following shot may even be a trifle quicker than the Python, owing both to the superior grip shape, and the excellent balance of the KC.
Just as an anecdotal note, last Sunday at the club, I was killing time (and cardboard) in a bay when a couple of friends stopped by. One, who had sixgun experience in the past but is a Glock shooter now, was so intrigued by the King Cobra he asked to try it. I gave him a few Comp IIIs with .38+Ps (my IDPA standard load, but doesn't make USPSA major).
He loved the thing, even the trigger. He's still talking about it.
That may have something to do with the beautiful finish. The blue King Cobra is simply gorgeous to look at, whether it's a downmarket gun or not.
BUT! King Cobras are awful guns and none of you should buy any.
Thanks.
