I had this problem as well and it is from the extractor. The extractor is supposedly one of the most finicky and one of the most common causes of malfunction. yes yes, I know that most malfunction are human error, ammo, and/or magazine however the extractor is a common problem. I would try different ammo and see if it happens with two different magazines. I believe limb wristing usually gets stove pipping not this type of malfunction.
Now if you still have a problem, I would have a gunsmith tune the extractor. Which basically means removing the sharp areas where the extractor grabs the cartridge and tunes the pressure it applies.
