I cannot speak to the diameter, length, nose profile, etc. of the bullets you mention but I can say that 124 grains would be about the optimum weight for casual shooting loads in a 9 mm Luger. 138 grains is on the heavy side but within the acceptable range. In fact, if you are handloading they might promote a longer OAL which is what the Luger wants for proper functioning.

As for a load, look for one that produces a velocity times bullet weight that is near equal to velocity times bullet weight for the 124 grain bullet. (In other words, drive the 138 grain bullet at about 90% of the velocity you would drive the 124 grain bullet at.) This will put you at a good impulse level for operating the action. In general, having the correct impulse level tends to be more of a problem than pressure when loading for the Luger. (But, as with any gun always keep the pressure within sane levels.)
