I'd like to use my M&P 9c for IDPA, at least sometimes, but I need to remove the mag lock, otherwise it's a PITA when I finish each stage and have to show the SO a clear gun.



I'm not sure what to use as a replacement spring, which I understand is a needed part.



Any suggestions as to what spring to get and where I might find one?

I think some one said that the spring on a bick ink pen works well. You just have to cut it shorter.

Also, if I remember correctly, I believe some used the mag catch spring from a 1911 ... cut down a bit.
