Failure to extract all of the way. No stovepipe. Haven’t tried different ammo, but will do that next. Gun is nearly new, even though vintage model.
Have you lubricated the interior really well? New condition pistols really need to be lubricated well until they are fully broken in. I use Lubriplate grease (as my Gunnery Sergeant taught me) on all barrel locking surfaces and slide rails and the recoil spring and guide until they are fully worn in. In the old days, my troops would get a lot of stoppages with the Browning M2 machineguns until I made them lubricate the heck out of them. They are machines, after all..
I would think that the chamber is nice and smooth inside but I might even wax or grease the cartridge cases at first until everything is worn in at about 100 rounds or so.
Another possibility is the magazine - the magazine lips might be bearing against the slide and impeding things.
