Not a Triple K fan! I have bought a few for vintage pistols that did not have original magazines as part of the sale. A few worked and a few were horrible. I guess their QC is not good. They are cheaply made, thin and not finished very well. I got rid of almost all of them except one that does seem to work 100%. I would not suggest buying triple K unless you are bored and need something to complain about and have to return.
