robhof,
I plan to make another one from a quality socket. The one shown here is from a foreign country that owns most of the U.S. national debt. I used it as a practice run; because it was in my tool box. It worked fine on the Colt because the nipples weren't tight/frozen. I suspect it would not hold up to rough usage.
As my Momma always said, "You get what you pay for."
