I've been shooting the crap out of my Shield. I had a couple FTF initially but after another stripping and cleaning I believe it was a small piece of debris in the firing pin area restricting the movement of the firing pin. Since then about 200 rounds with no failures. Nice pistol and more than accurate enough for what it is for - personal defense. Firing quickly I can empty the mag and keep all rounds in a 5" area center mass at 12 yards. Taking my time I can easily cut that group in half.
