What is the COL of the case , I have had this happen with my Trojan and I had to do a COAL specific for that pistol. It jammed up so hard I thought I would never get it to rack but finally didI wish I had taken a picture of the casing that was jammed......I left it at the shop.......the primer strike was normal as could be
Start by stripping the pistol and using the barrel to gauge your rounds. They should all drop in freely, such that the head of the case is flush with the barrel hood. That said, this problem usually causes a failure to go into battery, rather than locking up the gun after firing.
I am inclined to think that the problem with the gun locking up might be with the barrel link.
The stovepipes are probably a result of poor extractor tension. Take the slide off and slide a round under the extractor. It should be held in place securely, so that the round does not fall out from light shaking in any direction. If you have poor extractor tension, I would order a new one and bend the old one to tide you over until it arrives. The live fire test is to load a single round, remove the magazine, and fire it. The spent cases should consistently clear the ejection port with no magazine installed. Too much tension will prevent the case rim from sliding up under the extractor as it is fed from the magazine.

100% barrel link issue.
check the barrel link for a hairline crack, if not cracked, wrong link was put on it
They were reloads by custom reloading service 124 grain
I had other firearms not like these reloads, but never a jam this bad
I bet I know what it is.
I bought a Norinco NP-29 9mm 1911.
(I know it's a piece of crap, but it was on sale for $249 so who cares.)
I was having horrific jam-ups. Jamming so badly that I had to hammer a squib-rod down the barrel to get it un-jammed.
The problem was the barrel link. The distance between the two holes was too long.
It throws off the gun's timing. So the slide is trying to cycle, while the barrel is still locked to the slide.
I replaced the barrel link with a shorter one. And now the gun cycles just fine.
This is a known problem. You can actually buy kits with different link sizes to try.
Buy some new ammo. this is a ammo problem.
one fellow I know has a Springfield 9mm with a match ramped barrel, It will Not shoot your average reload, unless it is reloaded with a quality full length sizer die.
a lot of reloads you get a bit of a bulge and causes jams in tight chambers
Might try a 3rd type of ammo tomorrow, it just sucks when it jams up this hard, it's sickening to have to completely take gun apart every time, I have to beat on the barrel bushing so hard with it in a vice and hammer, it's outrageous and shouldn't be like this
