Those are all good molds, and I prefer steel, but if you want to save yourself a lot of future headaches, have on hand Lee double-cavity aluminum mold #90309, for a 125 gr. RN bullet. It is far cheaper than the others, casts bullets faster, and is the only one I know which makes a bullet (356-125-2R) with a shape and weight very close to what the German military used for many years, and through WW-II. I spent years trying to find a mold for this exact shape.
This is the standard shape that most 9mm pistols are designed to digest flawlessly, and most do so with this one.
Some of the other bullets have a little forward shoulder, which seems to have no other function than to cause jams. This particular Lee bullet does not have that.
Without the shoulder, and with this shape, the 125 gr. Lee bullet can be seated out far enough to achieve maximum specified overall length. This is important in avoiding feed jams in pistols including the Lugers. This bullet also keeps the single lubrication groove inside the case.
I use and recommend the other molds also, and they are fine with most guns, but if you want to be 100% sure, as with carry ammo, use this Lee bullet. Then shoot it in anything.
Only downside: I've found that with the Lee molds, I have to be rather careful when closing the mold blocks, as it's easy to get them out of line, making reject bullets. But no molds give you more for the money. You get the handles and everything, not just mold blocks.
