In my quest to find a new mag release (before I cut down the original) I accidentally stumbled on a post in a S&W forum about Shields dropping mags. (for right and left handers) Turns out there are 2 types of followers being used and shipped with Shields Some with and some without a relief cut to clear the mag release window in the mag body. So I loaded 3 rounds (to place the follower in the window) and marked the depth on front and side with a sharpie... I went into the garage and relieved them with a few minutes of file work.
Walla! My new gun is once again operating like a new gun! Shot 200 rds of mixed power and profile ammo yesterday without a stoppage. Everything from light target loads to +P JHP's and factory ball ammo in between.
Now, I'm off to see if I can get a couple properly made mag followers from S&W as the folks in that thread were sent.
Found this pic online showing the difference- if you have a Shield,45 you might want to verify which mags you have.
