I picked up a very heavily used Standard pistol, and at the range discovered that it would stovepipe very often; maybe once per magazine. I bought the Volquartsen extractor and tune-up kit and broke down the bolt and replaced the firing pin and the extractor.
Back at the range, the gun was 99%, literally. I shot 100 rounds of cheap Centurion ammo through it and it had one malfunction that appeared to maybe be a bad round. It is no exaggeration to say that the improved extractor made this into a new gun. If you have a Mark pistol that is experiencing stovepipes it is cheap, easy, and likely effective to fix the problem by applying this "tune up" kit.
Here is the product I am referring to; I reviewed it on Amazon.com: ("Helpful" clicks appreciated; let Amazon know that we are looking at their gun-related products!)

At one time I was hesitant to mess with the bolt assembly. Turns out that it is actually very easy to replace an extractor and the firing pin. Nice not to be afraid of this part of the gun.
Now the trigger and hammer groups; those I am afraid to mess with.
