Guess it was hit and miss then. I bought my USPf .40 in 1994. Bought all my 15 magazines for it between 1994-1999. They are all plastic. Tight as a drum, and have never failed, despite heavy use. I used them in USPSA production for 3 years, dropping magazines and reloading thru the stages. No problems with mine, or the 2 other folks I shot with that used HK USPs in USPSA production class. I still have them and use them. Keep about 5 of them loaded up in my range bag and the springs work just fine when used on the range despite how long it may be between loading them and getting time to go shoot.
