Browning Buck mark Feed issues

rc said:
Is the chamber clean? Sounds like your gun isn't seating the rounds all the way and the hammer strike moves the slide and doesn't have the force to set off the primer in that case. I had to chamfer my chamber to not shave lead and to make it smoother feeding and more reliable.

I carefully looked at the live rounds left in the chamber the next 6 or 7 times this malfunction happened since my last post. The live round appeared well seated. There were no marks in the head of the case. Not even a scratch. I bought & replaced a replacement OEM extractor and cleaned every moving part to the gun. I will go to the range and try it with the OEM extractor and see how it works by eliminating this one variable. Thank You for your reply.

I fired 40 rounds through the Buck Mark after installing the new OEM extractor & giving the gun a thorough cleaning. Other than 1 CCI Standard dud, all rounds fired flawlessly.
At this point I can only conclude it was a combination of the extractor and a much needed complete take down & cleaning.
 
Have you dry-fired the pistol much?
It sounds like chamber peening may be causing cases to hang up.
A less likely possibility is the rim relief in the slide face being too small - either because it is just too small, or because the ammo is out of spec and the rims are too large.

I have two Buckmarks with an estimated 210,000+ rounds through them.
The problems you're describing would usually be a filthy gun that needs a proper cleaning.
If there's an additional mechanical problem, it would typically come back to extractor, tight chamber, and/or ejector.


Edit:
That's strange. The last three (new) posts were not visible until I posted my reply. Gonna leave my post anyway.
 
Your problem is different from the one I encountered.. Magazine drops after a shot and the magazine drops ever so slightly. Thus no second shot after that (mag too low). Have to replace the magazine catch with a new one.
