M&P jamming resolved...

[hd78glide]

It was the weirdest thing, I could go through two mags without any jamming. When my wife was shooting, every second or third shot would jam on her.

After talked to a couple guys at the range, they new exactly what the problem was. My wife was "limp wristing" it. She was holding the gun too low on the grip. Once she went right up to the beavertail it worked much better for her.

It still jammed a couple times per mag, but that is due to her arthritic hands. She couldn't grip it quite firm enough, and she was absorbing much of the recoil with her body. If she can't compensate, I'll be looking to get a weaker recoil spring.

What kind of grip technique does she use?

 

[hd78glide]

She used a two handed grip. As for technique, good question. The only thing I can say, the weak hand is over the strong hand.

If she's limp wristing it she is not "locking" her wrist and it's bending and allowing her hand to move back with the gun under recoil, thus the slide isn't traveling back on the frame as far as it has to.
Holding it down to far on the grip will do the same thing, but that's physics at work and I suck at science.
Actually it's a matter of the gun being able to rotate in her hand because the bore axis is higher then it should be in her hand.
Practice, practice and more practice.

you can speed up the wear in process but cycling the pistol Many times. Make sure it is lubed enough,...but not too much.
