Cartridge O.A.L. is a critical measurement with Lugers to assure flawless function. This must also apply to your .45s, as it is designed into the system. Too short of an O.A.L. will, typically, lead to jamming with the higher rounds in a Luger's magazine.

Do you guys handload?

Feel free to shoot any ammo you choose, but firing cheap ammo through your two Cadillacs would seem to me to defeat the purpose of having made a costly investment in the first place.

No, the .45 does not have a stepped chamber.

Not holding open likely means a need for hotter ammo, or more lube or just more break in time.
The mainspring on the .45 is also quite strong. I changed the spring on mine to a weaker one and was able to get mid range match ammo to function the mechanism, but not feed due to the unique shape of the 185 gr match bullet. That was an interesting exercise, but I changed the mainspring back to the original.

The magazine spring is also quite strong, and likely contributing to the feed issue. Try loading 5 rounds. It is really tough to get 7 into some of the magazines

Eugene has recommended the Wolf ammo.
An expensive pistol does not require expensive or hand loaded ammo.
S&B .45 ball ammo worked quite well in my lugerman .45.
So well I bought 500 rounds, and it was the "cheapest" available at the time.
