Magazine springs and slides locking back

[GSMD Fan]

I have noticed a disturbing trend. My slide on my 92FS will not lock back with some of my magazines. Yes I know I shouldn't shoot them dry.
Anyway I am having problems with some magazines. Is it the gun? I don't think so. Ammo? Not really , all factory loads usually Winchester. I am guessing it is the mag springs. Yes they are old and have seen a lot of shooting. Much of it was work related.
Any suggestions? Any clue were I could get new mag springs for 15 rd 92FS magazines? Buying all new ones would get pricey.
Thanks.

there may be other places, but off of the top of my head you can try

www.brownells.com
www.berettapistols.com

if you look around on the net, you might get better prices, depends on how many mags you need to restore

I have also seen slides fail to lock back because the follower had been damaged, and there was not enough material left to activate the slide lock
