My wife has a new LC9. We went to the range today and it performed fine with the (extended pinky) made in Italy magazine the pistol came with. But, the Ruger branded flush fit (USA made) we bought as an extra had issues. After firing a round and the slide racks itself it would release the magazine. And we were careful to make sure we weren't inadvertently hitting the mag release button while shooting. Anyone know anything about this type of issue?
