Hi,47Ds wouldn't lock the slide on my '42 Colt.
Not to get too far afield, but I stored the mag loaded for over fifteen years, taking it out and putting a few rounds through it every five years, and it always worked perfectly, other than not locking that G.I. Colt. It's not that the follower failed to lift the slide stop, the follower slipped past the slide stop; I'd expect a mag to stop feeding reliably long before the spring was too weak to lift the slide stop.Hi,
Probably a weak mag spring which the 47D's were known for, of course CS is excellent with Wilson.
I just buy Wolff's 5% extra power springs and all is good.
I have about 15, 47D's and they have never let me down,and...
I use them for carry.
