mine did not feed well with Wolff extra power recoil springs installed. Sometimes the slide would close without catching a round. It has never done this with any other mag and since I was not going to carry with the 10 rounders anyway, I just sold them (with full disclosure of course).
The only way I was ever to get my 10rd mag to feed 100% reliably was to remove the 10rd spring and stuff 2 7rd springs in the magazine. Fed well. Only problem was, with the two springs in there, I could only load 7 ROUNDS IN THE MAGAZINE!
