Picked up a Shield in 9mm for the wife. Have about 600rds through it to date. Have mainly put WWB through it and have at least 1 stovepipe per 100rds. Initially thought the wife was limp-wristing, but starting experiencing stovepipes myself when I fired it. Not giving up hope just yet, I really like the little pistol.

Any ideas about the stovepipes? Weak WWB ammo? Strong recoil spring, or both?
