We bought a M&P 380 Shield EZ for my wife for Christmas. We have an LCP that she could carry, but like many people, she really did not like to shoot it. She finally decided that we could get a new gun that maybe she would actually like to shoot, and we settled on the Shield EZ. Unfortunately, I think she has a problem limp wristing the gun (even when consciously trying not to do so), but I cannot replicate the problem when I shoot it. At any one range session, she will have mixture of failure to eject, stovepipes, and failure to feed. Most recently, a problem of some kind happened approximately every 4-5 rounds. Whenever I fired it (using the same ammo and magazine), it had no problems. We were using Winchester Train rounds and reloads at the time. Today, I shot it by myself trying to cause it to jam. If I held it loosely one handed, I could get it to repeatedly failure to fire on the second round, but it was due to not holding the grip safety tight enough because it would fire on the second trigger pull with a tighter grip. I was shooting Aguila and Monarch ammo (trying to use the cheapest ammo to see if quality made a difference) and some reloads. On the last reload round, I had a failure to lock back on empty. Previously, I had managed to cause some jams using light reloads, but the new batch have a higher powder charge with no problems except today. The odd thing is, she has never had a jam with the LCP or LC9 (just problems actually pulling the trigger) or a Rock Island 1911 full size 9mm. I am speculating that part of what makes the Shield EZ "easy" is really weak springs to make it easier to rack but prone to other issues. It really is the easiest gun I have ever racked, but I wonder if even a slight limp wrist is enough to cause a problem. She also tends to hit low, which makes me wonder if she is flinching in anticipation of the recoil and loosening her grip at the last moment before squeezing the trigger. My wife is very small, so nearly every gun she has tried has some problems for her. From my research, the solution is just shooting it more and getting used to the recoil. However, if I could consistently replicate the problem, I could be more sure that it is a shooter problem and not a gun problem. Anyone have any experience with a similar problem using a Shield EZ and a petite shooter.
