is a cobra 380 nickel plated or chrome plated hand gun worth
I have no idea. This "cobra" is not a Smith & Wesson handgun, so far as I know.
I'll move your post to our Other Handguns forum. Perhaps there someone can help you.
The Cobra Enterprises is a very inexpensive blow back .380. They have really bad reports on dependability and are prone to misfires and jams.
Several online sites have them for $105-125 depending on finish.
