Hi guys. I have about 400 rounds through my Shield and have experienced quite a few double feeds. I have used several brands of ammo. The firearms instructor I trained with was pretty suprised. Is this a break in issue or something else?
...It is a single stack magazine...
CS will probably tell you what they told me - the Shield likes 124g.
Also have a look at the mags to see if the feed lips might have been bent. I've done that myself with a mag loader.
Is this a break in issue or something else?
