The quickest and easiest possible fix.
Install a fresh recoil spring. <~~~
I think your factory standard spring weight is 16# - so buy a 16# & also a 17#
Call Wolff Gunsprings - They will have the factory standard recoil spring and a slightly higher power.
Also try a fresh magazine in case your mag feed lips are out of whack.
Factory magazines for that pistol are all over Gunbroker.com
You should install a fresh recoil spring no matter what. Another magazine you can always use anyway.
And if none of the above work then have a local gunsmith check your extractor.
That gun should crank them out all day long without a hitch.
