Is there any way to fix such a problem, or is it just the way they are? Any help with this matter would be greatly appreciated. 
ETA: I was told to tell everyone that this did not happen with Pennsy's P220, so I'm sure he must have gotten a "Better" one.  |
When a particular specimen exhibits odd behavior it's typically the "tolerance stack" of that specific pistol. In this case I would say it's tolerance stack and a weak magazine spring.
The way the pistol was designed to work was insert a fully loaded magazine and then manually cycle the slide to chamber the first round. At that point there is a relationship between magazine spring tension at -1 capacity and slide velocity.
It would seem to me that with full slide velocity from a cartridge discharging and the magazine at full spring tension with 7 rounds instead of 6 (or 8 instead of 7 if it's an 8 rd mag), the magazine spring is probably wearing out and not pushing the bullet "up" in time for the slide to strip it out of the magazine. IOW the spring isn't strong enough to push 7 (or 8) rounds "up" fast enough.
IOW, the inertial dynamics of your pistol are screwed up because of a weak mag spring or it simply can't accommodate a full mag + 1 because of it's tolerance stack.
Stop shooting it +1 for awhile and see if the problem abates. Or, change the magazine spring.
Magazines: Don't fall in love with them. They are disposable. Springs can be replaced but mag bodies swell as do feed lips. There's a very delicate balance between the geometry of the magazine, mag capacity, spring tension and the slide velocity of a given pistol.
