How do I solve primer wiping . . ..

I have some what appears to be primer wiping with my semi-auto pistol. Will a slightly heavier recoil spring solve the problem?

He is talking about when the firing pin leves a gash instead of a clear dimple. Generally because the firing pin is not retracted by the time the shell hits the ejector.

I get this sometimes too, I'm curious what people think?

I thought it was the barrel dropping before the fireing pin is pushed back by its spring. Then there are fireing pins without springs.

For what ever reason, some guns do slide the barrel down while the fireing pin is extended.

OH, probably happens on glocks because the fireing pin is held down by the striker spring. In that case it may be common to any pistol with a dropping barrel and a striker instead of a hammer.

Best thing is to order a wolfe firing pin spring of a heavier tension than you already have. The firing pin is not retracting fast enough, before the action is beginning its cycle.
A heavier main spring would help some, and when you read the Wolfe literature, you should be changing the main spring more often, but I also like to include the firing pin spring as well.

Hey happy, I agree with Shondor about the Firing Pin Spring.

But, the first thing I'd suspect is the Firing Pin, it's Spring and that portion of the receiver may just need a good cleaning. It is not uncommon for crud to build up in and around these parts which slows the retraction down slightly.

I've no idea how you go about your cleaning routine, but a "spray and wipe" often isn't good enough to keep the Firing Pin working correctly.

You have to achieve a "lightly lubed" condition to slick it up, but not so much as to draw excess powder residue. After a good tear-down cleaning, I lightly oil the Firing Pin, Spring and their recess and then wipe off any excess with a cloth.
