What you need to find are mags that fit the "military" frame High Standards,
"The Victor's" came only in this configuration.
Models 106 and 107 come to mind.
Don't buy the aftermarket mags they are too soft in the feed lips and will give you nothing but grief.
Spend your money on a original with the Red plastic floorplate and you will have no feeding issues.
Only small tuning of the feed lips may be required, once set, you are good to go.
Good luck finding one...
