For a while these were highly sought after and nearly impossible to find. They are much easier to locate now.
The Shield uses single stack magazines to help create a much slim and easy to conceal frame. The magazines are not compatible with the other M&P pistols that use double stack magazines.’
The pistol is available in 9mm or .40 S&W.
The trigger has a very distinct reset (like a Glock) that is missing on the factory triggers of the full-size and compact size M&P pistols.
Smith & Wesson recommends that you limit your use of +P ammunition as it will wear out the pistol much faster (unlike a Glock in which you can use +P ammunition all of the time). S&W says not to use +P+ ammunition at all.
I recently bought a Smith & Wesson Shield in 9mm. I don’t normally get giddy about guns, but I can’t believe how great it shoots, and how easily is conceals in a Kydex in-the-waistband holster. It won’t replace the Smith & Wesson 642 J-frame revolver that’s been in my pocket for 20 years, or the Glock 26 that also rides in a Kydex IWB holster, but it will definitely be a frequent part of my everyday carry. Just like when you have another baby, you don’t love your other children any less. Your heart creates more love for the new child. My heart has created new love for the Shield.
The following YouTube videos provide some good reviews of the new S&W Shield pistol.
