Maybe i missed something but why would you or anyone opt out for a holster that is for a different pistol altogether when Fobus makes one just for the Shield. Try going to there web-site,>
Fobus Holster: S&W M&P Shield - EVOLUTION PADDLE HOLSTER
S&W M&P Shield - EVOLUTION PADDLE HOLSTER. I found this simply by looking in a Goggle search, > (Fobus paddle holster for the Smith & Wesson Shield.) And the site came right up wth it. What more can i say. If your looking for a reasonably priced holster and one that will not be affected by weather conditions/Humidity/perspiration etc. it's a very logical decision!
