I am very happy for all the folks out there that got a good one (Shield). Could be I am wrong but the Shield should be able to shoot any of the three reliably. I figure someone will say it needs another 500 rounds to break it in? Shooting $200 dollars’ worth of ammo through a gun to see if is reliable is silly. At this point I am getting a little frustrated to say the least with S&W. I called my gun dealer, he said two other guys brought there Shields back with the same issues this week. He is sending a letter to S&W. I am beginning to think S&W has a real problem on their hands? I am going to be persistent and call them and keep sending it back till they get it right.
