I've had my Shield 40 since the end of January 2013. I'd guess I have somewhere around 500 rounds through it. I had one FTF & one FTE in the very first magazine I shot, since then I've had ZERO malfunctions of any kind. I prefer the extended mag when carrying and the standard (shorter) is my back up carry magazine. For a lightweight, smaller size polymer handgun, the recoil is surprisingly reasonable and the accuracy is better than I expected. I am glad I bought it.
