This is my first post on the site. I've been wandering around the boards for a while now, and I must say I'm very impressed. I wanted to make my first post actually have some point, so forgive me if this topic has been hit on before.

I carry a USP40 as my duty pistol. I have one magazine that does not lock the slide back once it's empty. Can anyone tell me what might be wrong with the mag and how to fix it?

Spring is worn.  HK uses really weak factory springs.

Same thing happened to my USP 45.  Both mags.  Sucks.

Wolf makes 10%+ mag springs, which are about $7 each.  Good investment.

Excellent. Thanks much!
